A student wants to compare the amounts of CO2 given off by yeast provided
with different amounts of sugar. The student places a balloon over each
container to catch the released CO2. How can the student make quantitative
observations of the CO2 collected in the balloons?
A. Describe the shape of each balloon.
B. Approximate the relative size of each balloon.
C. Measure the circumference of each balloon.
D. Count the individual CO2 molecules in each balloon.
Answer:
So others don't get confused, the answer would be Measure the circumference of each balloon
Explanation:
The student will utilize the following factors to make quantitative observations of the carbon dioxide collected in the balloons which are describing the shape of each balloon, the relative size of each balloon and measuring the circumference of each balloon.
What is Yeast?
Yeast is a type of fungus that undergo fermentation, where it converts sugar into energy and carbon dioxide is produced during the process as a byproduct.
When sugar in different amounts is provided to the yeast, the carbon dioxide concentration will also differ accordingly. More fermentation leads to more sugar production which leads to increase in level of carbon dioxide.
The shape of the balloon determines the volume of carbon dioxide produced. The amount of carbon dioxide produced in each container is compared by the relative size of each balloon and measuring the balloon circumference will help to calculate the volume of gas.
Therefore, describing the shape of each balloon, the relative size of each balloon, measuring the circumference of each balloon are very important factors to determine the carbon dioxide collected in balloons.

Algal blooms, and the rapid proliferation of photosynthetic plankton can ultimately end up depleting all the oxygen from a body of water
Answer:
True
Explanation:
The proliferation of phytoplankton (microalgae) may decrease the visibility which causes oxygen (O2) depletion because they consume important amounts of O2 during the night and cloudy days. An algal bloom refers to the sudden increase in the population of algae in water bodies. These algae consume O2 and block the sunlight from underwater plants. As the algae die and decompose, O2 concentration in the water decreases, and, in consequence, most aquatic life that depends on oxygen dies.

This animal has a protostome developmental pattern and a trochophore larva. Identify the major clades that this animal belongs to
Answer:
Lophotrochozoans (it is a protostome)
Explanation:
Lophotrochozoa is a group (clade) of protostome animals, i.e. animals that undergo a developmental pattern in which the blastopore develops into the mouth. Lophotrochozoa clade includes bryozoans, annelids, molluscs, brachiopods, and platyhelminthes. Most lophotrochozoans have either a lophophore or trochophore larvae during the planktonic stage. A trochophore larva is a marine planktotrophic larva with several bands of cilia that form the locomotory organ (i.e., the prototroch), which is only found within the Lophotrochozoans.
When the larva and the adult form of an organism are different from each other this type of development is called indirect development. For example Porifers and platyhelminthis.

Why are economic impacts important to consider when planning to address climate change? Wealthy people and businesses won't support changes if the changes are not beneficial to them in the short term Climate change is the most significant danger humans face in the next 100 years We only have limited resources and so should use them where they will do the most good Without substantial economic sacrifice the world will suffer significant, inextricable (cannot be undone) damage due to climate change
Answer:
The projections, if they play out, illustrate the potential magnitude of decisions such as the recent one by President Trump to walk away from the international Paris climate accord, in which more than 170 countries agreed to slash their carbon emissions in coming years. Meanwhile, hundreds of governors, mayors and other elected officials have vowed to continue the shift toward cleaner sources of energy.
Hsiang acknowledged that despite the researchers’ efforts to use sound statistical approaches and a wealth of databases, calculating the future costs of climate change is inherently uncertain. Communities are likely to adapt and become more resilient. Industries evolve and relocate.
Delavane Diaz, a senior technical leader at the Electric Power Research Institute, agreed that the study has limitations. For one, it fails to account for how humans will probably plan for and respond to the changing climate. Still, she said, the conclusions provide an important glimpse of the economic risks the United States could face as global warming worsens.

Examine the mechanism of carbonic anhydrase. If the Zn2 were removed from the active site, and replaced with either Cu , Cd2 , or Fe3 would you expect the enzyme to still be functional
Answer: No
Explanation:
Carbonic anhydrase (CA; carbonate hydro-lyase) is a zinc-containing enzyme that catalyzes the reversible hydration of carbon dioxide: CO2+ H2O<-->HCO3(-)+H+. The enzyme is the target for drugs, such as acetazolamide, methazolamide, and dichlorphenamide, for the treatment of glaucoma.
The zinc ion is located in a cone-shaped cavity and coordinated to three histidyl residues and a solvent molecule. Inhibitors bind at or near the metal center guided by a hydrogen-bonded system comprising Glu-106 and Thr-199. The catalytic mechanism of CA II has been studied in particular detail. It involves an attack of zinc-bound OH- on a CO2 molecule loosely bound in a hydrophobic pocket. The resulting zinc-coordinated HCO3- ion is displaced from the metal ion by H2O. The rate-limiting step is an intramolecular proton transfer from the zinc-bound water molecule to His-64, which serves as a proton shuttle between the metal center and buffer molecules in the reaction medium.
what are the three strategies that the community could place to work with governmental structures to stop illegal dumping
Answer:
Illegal Dumping has gotten out of hand. According to the Los Angeles County Public Works, “People usually dump illegally to avoid collection and disposal fees, or because they believe proper disposal is just ‘too much trouble’.” This is very unfortunate for our communities who receive the negative consequences of higher taxes for cleanup, environmental hazards, and a breeding ground for rats.
The cost of a one-time cleanup and detoxing of an area can cost thousands of dollars. But to leave the mess is just not an option. The best option is to stop the illegal dumping before it happens, preventing the cost of cleanup, preventing the chemicals and toxins from entering the ground water, and preventing the rats and mosquitoes from breeding. The best areas to live are communities that care about their community! So, what can a community do to prevent illegal dumping?
Here are some key points to help deter illegal dumping:
Educate the public through the schools and through community awareness groups about the costs, chemical hazards and dangers incurred by illegal dumping
Create safe, public-friendly waste disposal options and advertise them
Create laws that impose stiff fines for the perpetrators and advertise these stiff fines
Use Illegal Dumping Cameras to catch the perpetrators in the act
Use Social Media to ask the public to identify the perpetrators
Follow through with quick clean up
These steps will invite the citizens to be involved and help deter the criminal activity of illegal dumping within your community.

How does human population growth and resource use impact biodiversity?
As human populations increase, the demand for resources such as food, water, and energy also increases.
What is biodiversity?Biodiversity refers to the variety of life on Earth, including the variety of species, ecosystems, and genetic diversity within species.
Human population growth and resource use have a significant impact on biodiversity. This leads to habitat destruction, pollution, and climate change, all of which have negative impacts on biodiversity.
Habitat destruction: As human populations grow, they need more land for agriculture, settlements, and infrastructure development. Pollution: Human activities such as industrialization and transportation produce pollutants that can harm biodiversity. Climate change: Human activities such as burning fossil fuels for energy production lead to the emission of greenhouse gases, which contribute to climate change.Thus, human population growth and resource use impact biodiversity by causing habitat destruction, pollution, and climate change.

There is a claim that lycopene, the reddish substance in tomatoes and peppers, is of value in protecting people from Alzheimer Disease, a neurological condition. How would you, as a Biomedical Research Scientist, go about to refute or substantiate this suggestion?
Answer:
Conduct a study to determine if lycopene obtained from tomato and pepper consumption is significantly associated with a decreased level of abnormally folded proteins in neurons of the cerebral cortex
Explanation:
Alzheimer's disease is an irreversible, progressive, brain disorder characterized by the loss of neurons (the main brain cells) and synaptic connections in the cerebral cortex and specific subcortical regions. It has been shown that Alzheimer's disease is associated with an abnormal folding of proteins such as amyloid and tau proteins in neurons, thereby leading to the loss of communication between brain cells. In consequence, in this case, it should be interesting to design a study in order to observe if lycopene obtained from tomato and pepper consumption can decrease the levels of abnormally folded proteins in neurons of the cerebral cortex, which is a pathologic hallmark of Alzheimer's disease. For this purpose, it is expected to form two groups of study: 1-one group composed of individuals that regularly consume tomatoes and peppers and 2-one group composed of individuals that do not consume these fruits, as well as a third 'control' group composed of individuals that obtain lycopene by consuming other plants (e.g., watermelon, pink grapefruit and redd carrots which are also high in lycopene). Subsequently, it should be necessary to experimentally determine if lycopene is significatively associated with a decreased level of abnormal amyloid and tau proteins in neurons of the cerebral cortex. Finally, the comparison between individuals that regularly consume tomatoes and peppers with the control group may result useful to determine if different lycopene sources may affect protein folding.

What is Theory of Evolution?The theory of evolution, also called the "theory of evolution by natural selection", was proposed by Charles Darwin and Alfred Russel Wallace in the nineteenth century.
Darwin further stated that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this theory, each species has its own distinct lineages or genetic differences that come from a common ancestor, gradually accumulating over a very long period of time.
This theory explained that birds had moved from the mainland to the islands, and that species gradually evolved to fit their new environments. Natural selection occurs because organisms in a population usually have randomly occurring gene variations and mutations that affect adaptation.
Thus, they made documented and shared many scientific observations related to biogeography and comparative anatomy . So, the correct option is (C).

Describe the inflammatory process that occurs and include the role that neutrophils and monocytes
Answer:
Inflammatory process: When the body is invaded by germs or a bacterial infection, the body’s immune system will respond to it by creating antibodies and sending white blood cells to fight the germs or infection. As the immune system interacts with the invading pathogen, the infection site will go through the inflammatory process. This process will vary, depending on area that is being affected. It usually will consist of an injury response, an immune response, tissue healing and wound repair. As the body goes through bacterial or physical trauma, it will immediately respond by sending white blood cells to the area. Produced in the lymph nodes and in bone marrow, white blood cells are released into the bloodstream, devouring and cannibalizing the invading pathogens. As part of the inflammatory process, the localized area usually will become tender and particularly sore. If the trauma is on the skin, then the area also will be prone to discoloration. The inflammatory process is closely linked to the immune system. The immune system will dilate the blood vessels, forcing blood that is rich with oxygen and white blood cells to surround the trauma area. Inflammation is the accumulation of white blood cells as they surround and kill the invading pathogen. As the trauma area heals, there will be a certain amount of pus. The pus is a collection of dead cells from the invading pathogen as well as cells produced by the immune system. Some swelling usually will occur during the inflammatory process. Protein and water will surround the area, making the area inflamed and slightly disfigured. The protein will contain antibodies to protect the area from being re-infected and will encourage tissue growth and healing. Pain can be an ongoing component of the inflammatory process. As the physiological aspects of the trauma area change, the area can be continuously painful and tender. The inflammatory process usually ends as soon as the invading pathogen is eradicated or as soon as the trauma area heals. Pus formations will usually stop, the area will become stable, and inflammation will subside.
Role of neutrophils & monocytes:
Tissue Macrophage Is a First Line of Defense Against Infection. Within minutes after inflammation begins, the macrophages already present in the tissues, whether histiocytes in the subcutaneous tissues, alveolar macrophages in the lungs, microglia in the brain, or others, immediately begin their phagocytic actions.
When activated by the products of infection and inflammation, the first effect is rapid enlargement of each of these cells. Next, many of the previously sessile macrophages break loose from their attachments and become mobile, forming the first line of defense against infection during the first hour or so. The numbers of these early mobilized macrophages often are not great, but they are lifesaving.
Neutrophil Invasion of the Inflamed Area Is a Second Line of Defense. Within the first hour or so after inflammation begins, large numbers of neutrophils begin to invade the inflamed area from the blood. This is caused by products from the inflamed tissues that initiate the following reactions: (1) They alter the inside surface of the capillary endothelium, causing neutrophils to stick to the capillary walls in the inflamed area. This effect is called margination. (2) They cause the intercellular attachments between the endothelial cells of the capillaries and small venules to loosen, allowing openings large enough for neutrophils to pass by diapedesis directly from the blood into the tissue spaces. (3) Other products of inflammation then cause chemotaxis of the neutrophils toward the injured tissues, as explained earlier. Thus, within several hours after tissue damage begins, the area becomes well supplied with neutrophils. Because the blood neutrophils are already mature cells, they are ready to immediately begin their scavenger functions for killing bacteria and removing foreign matter.
What colors of light are absorbed? Which color is not absorbed?
Answer:
All colour except which is already present in the body.
Explanation:
The plant leaf has green colour so the plant absorb all the colour except green. The presence of green colour causes reflection of green colour so that's why we can see the green colour of the leaves. Every material or substance have a specific colour which can be seen when they absorb all light except the colour which is already present in it so we can say that that colour is not absorbed by the body which is already present in it.

When blood glucose levels rise, the hormone ___ is released from the ___ to convert excess glucose into glycogen, a short-term energy storage molecule for the body.
Answer:
insulin; pancreas.
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
Generally, when the blood glucose levels of a person rise, through an endocrine system, the hormone known as insulin is released from the pancreas to convert excess glucose into glycogen, which is typically a short-term energy storage molecule for the body.
In conclusion, the endocrine system maintain homeostasis by releasing insulin from the pancreas to decrease blood sugar and releasing glucagon to increase blood sugar.
