Suppose that you were discussing cell theory with someone who has little understanding of biology. Which object could you best use as an analogy to explain the evolutionary history of modern cells?
Answer:
evolution of human works
Explanation:
The cell theory states that all living forms are composed of cells. These cells are the basic structural units of all organisms and they evolved from pre-existing cells present in primitive living forms. From a biological point of view, the evolution of cells is similar to the evolution of human works, which were during the beginning of human civilization less specialized than in modern times. Likewise, somatic cells present in evolutionary recent multicellular organisms are capable of carrying out more complex functions than primitive cells present in unicellular organisms.
Which of the following best describes how does latitude affect biomes?
Higher latitudes receive less sunlight producing cold biomes.
Latitudes affect how much rainfall a biome will receive.
Lower latitude biomes will always have high temperature.
Higher latitudes produce warm biomes.
Answer:
A) higher latitudes receive less sunlight producing cold biomes
Explanation:
Biomes are determined primarily by temperature and precipitation. Generally speaking, biomes at higher latitudes (further away from the equator) are cooler and drier. Closer to the equator, biomes are generally warmer and wetter, as warmer air holds more moisture than colder air.

A grassy meadow high in the Sierra Nevada Mountains of eastern California is known to support a variety of organisms. During the summers when grass is thick and lush, and wildflowers abound, butterflies take advantage of this abundant nectar source. Bears graze on the berries in shrubs at the edge of the meadow. Deer also forage at the edge of the meadow. In the early mornings, coyotes are known to prey on the squirrel and mouse populations that burrow into the meadow soil. A variety of birds prey on the butterflies and other flying insects, such as bees and wasps.
If the biomass of flowers that support the butterflies was known to contain 100,000 units of energy, and certain bird species were eating the butterflies that foraged on the flowers, what amount of energy, on average, could be expected to be transferred to the birds?
Group of answer choices
a)100
b1,000
c10
d10,000
e50,000
Answer:
b) 1,000
Explanation:
In a typical food chain as described in this question, flow of energy occurs from one organism to another when they feed/fed upon. As one organism feeds, energy gets transferred to it. However, only about 10% of the available energy in the lower trophic level gets transferred because majority of the energy (about 90%) is lost as heat during metabolic processes of the organism.
Hence, if a flower contains approximately 100,000 units of energy and is fed on by butterflies. 10% of 100, 000 = 10,000 units gets transferred to the butterflies.
Likewise, the butterflies gets fed on by certain bird species. 10% of the available 10,000 units of energy in the butterfly gets transferred to the birds.
= 10/100 × 10,000 = 1000 units of energy.

Staphylococcus aureus (remember that an organism’s scientific name can also be written with the genus name abbreviated—in this case, S. aureus) is a bacterium, one of the groups of microorganisms. Although the different groups of microorganisms share some similarities, there are several important differences that distinguish each group. Drag each of the following statements to the appropriate bin to indicate whether it is a characteristic of bacteria archa fungi, or viruses.1. Derive nutrition from organic or inorganic sources or conduct photosynthesis2. Have cell walls that contain peptidoglycan3. Not typically associated with human disease4. Found in extreme environments5. Eukaryotic6. Can be unicellular or multicellular7. Cannot survive outside a host cell8. Can be seen only with an electron microscopeA. BacteriaB. ArchaeaC. FungiD. Viruses
Answer:
Viruses: Found in extreme environments. Cannot survive outside of a host cell, can only be seen with an electron microscope
Fungi: Obtain nutrition from organic or inorganic sources or carry out photosynthesis. It is not usually associated with human diseases. Eukaryote: It can be unicellular or multicellular.
Bacteria: They have cell walls that contain peptidoglycan. Found in extreme environments (via spores)
Explanation:
In the part of the answer, the answer was given by grouping the different characteristics of the microorganisms, classifying them into three groups.
Viruses are considered microorganisms that need the replicative machine to reproduce their RNA or DNA, this is how it is doubted whether they are living organisms or not.
Fungi belong to a very broad group of subtypes, but they all refer to the fungi kingdom, they are in the form of spores in the soil or in the air, those fungi that are considered pathogens for humans, such as the generators of histoplasmosis, or blastomycosis. Most fungi are not pathogenic to our body, so some are edible, such as yeast.
On the other hand, and finally we have bacteria, which are a family that is classified into many groups according to their genus and species, their shape is what determines their nomenclature, such as those coconuts, which are grouped together in a of bunch of grapes and are called thus streptococcus in synonymous to this method of colonization and form. Many bacteria are typical of our commensal flora or microbiota, others are not, thus generating opportunistic infections or severe infections.

Explain the purpose of the pH scale and what does it measure?
Answer:
pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water. Water that has more free hydrogen ions is acidic, whereas water that has more free hydroxyl ions is basic. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically.

This frog is about to be food for a snake. Which type of nutrition does the snake use, and which type of nutrition does the frog use? Justify your answer.
Answer:
Both snake and frog are vertebrates and non vertebrates animals.
Explanation:
Snake is a reptile and almost used vertebrates and non-vertebrates in their nutrition. There are few species that are specialized in egg feeder, snake is one of that.
Most of the species has to fed 1 2 in a week. Snake used to eat most pups, mice, rabbits and ducks. Both frog and snake are carnivores. They eat prey, insects, mammals. Both snake and frog comes under the food chain. Frog eaten by snake or snake can eat frog.
Answer:
All animals are other-feeders. Their cells cannot make food for themselves like plant cells can. They gain energy and nutrients by eating other living things. The snake will get energy and nutrients by eating the frog. Frogs get energy and nutrients by eating other living things, such as insects and worms.

EXPLAIN The scuba diver is a living system. The scuba gear, or self-contained
underwater breathing apparatus, is a system of air exchange. How are these
the body's response
. ,
Answer:
Breathing in human on land or during swimming or scuba diving, the human inhales oxygen and exhales carbon dioxide, These carbon dioxide molecules creates "air bubbles" that are then ousted into the water body. The diver at that point draws air from the pressurized air tank, and can inhale or breath. This permits the diver to remain submerged for any longer than only one inhale, and can travel deeper underwater.
Inside this framework, the Oxygen is primary input to the oxygen tanks, which are then utilized by the scuba diver. The diver would draw the oxygen from the tank considered as output in this system.

What is the outcome of all chemical changes when two substances are combined?
A- A new substance forms with identical properties
B- The two substances release an odor
C- The two substances change color
D- A new substance forms with different properties
Answer:
D- A new substance forms with different properties
Explanation:
When a chemical change occurs, it causes the matter to form into a completely new substance. Because of this, the new substance will have different properties than the original substance. Options B and C are true for some chemical changes, but not all changes. Option A is incorrect because the substance has different properties than the original substance. Thus, Option D is correct.

How could the tomato plants response to being eaten by a hornworm caterpillar be described as a function of homeostasis
Answer:
First, it's important to get clear on the meaning of Homeostasis.
In simple terms, it refers to the capacity of a living thing (plant or animal) to react or behave in such a way that enables it to continue to survive irrespective of changes in its immediate environment.
Explanation:
In humans, the body has a system which reacts to the external stimuli of temprature. When the weather is hot, the brain through a sequence of electrical and chemical signals tells the skin to open up the pore, then we experience venting of sweating which cools the body and regulates internal heat. This is an instance of homeostasis.
This does not mean that the plant or animal is completely immune to such external changes.
In the case of the tomato plant, the hair on the leaves and stem of the plant is an example of Homeostatic responses which have evolved over the years to discourage predators such as the hornworm caterpillar from defoliating the plant.
Cheers!
Answer:
Please find the detailed explanation to this question below.
Explanation:
Firstly, homeostasis is the ability of an organism to use internally-controlled mechanisms to maintain a stable internal environment despite changes in its external environment. Homeostasis is an important phenomenon necessary for the survival of living organisms.
Hornworms caterpillar are notorious pests of tomato plants. However, tomato plants have been found not to stand still and get devoured. The plant responds to being eaten by these caterpillars by releasing chemicals that distracts their attention from the host plant and instead the caterpillars feed on one another.
Getting fed on by plants can disrupt the internal structure of plants, hence, the release of this defense chemicals by tomato plants is physiologically controlled in response to environmental stress i.e. pests, and it is done in order to maintain a stable internal condition. Therefore, the response of tomato plants to caterpillar pests is a FUNCTION of HOMEOSTASIS.

Which of the following statements is true? Group of answer choices All forms of life employ the same genetic code mRNA is the only type of RNA found in the living system A typical human liver cell has one set of chromosomes Organisms interact but do not affect their environment
Answer:
All forms of life employ the same genetic code
Explanation:
The genetic code refers to the set of rules that facilitates the translation of nucleotide sequences into amino acids sequences (proteins). mRNA is read in a group of three nucleotides called CODON, which specifies a particular amino acid. The totality of all codons makes up the genetic code.
However, one of the characteristics of the genetic cos is its UNIVERSAL nature. The genetic code is said to be nearly universal meaning that the genetic code is the same in almost all living organisms with few exceptions. For example, AUG codon encodes Methionine amino acid in all forms of life.
Hence, All forms of life employ the same genetic code is TRUE. Note that, tRNA and rRNA are other types of RNA found in living systems. Also, liver cells are diploid i.e. has two sets of chromosomes. Lastly, interacting organisms affect their environment
All the forms of life employ the same genetic code.
• It is true that all the forms of life exhibits the same genetic code, however, they do not possess similar genome.
• The set of rules used by the living cells is known as the genetic code.
• It is used to translate information encoded within the genetic substance, that is, mRNA or DNA sequences into the proteins.
• The genetic code is greatly identical among all the organisms and can be articulated in a simple table with 64 entries.
Thus, the correct statement is that all the forms of life employ the same genetic code.
