Hope this helps
The body part picked is ; The Heart
An injury or disease to the heart will stop the whole body functioning and the process modeled will be distorted
The heart in the body is equivalent to the engine of a car, The heart pumps oxygen carrying blood cells into all the organs and without this oxygen carrying blood cells the whole body will stop functioning ( i.e. The organs will be dead ).
An injury or disease to the Heart will negatively affect the distribution rate of blood to all parts of the body and this will negatively affect the overall wellbeing of the body and this will also negatively affect the process been modeled as well.
Hence we can conclude that The body part picked is ; The Heart , and An injury or disease to the heart will stop the whole body functioning and the process modeled will be distorted

Which letter marks the zone of inhibition?
Answers
Answer:
A. B
Explanation:
"B" as labelled in the above is the zone of inhibition.
The Zone of Inhibition is actually a test which is used to assess antimicrobial activities of a material or solution in relation to an micro-organism as a target. It is also known as Kirby-Bauer Test. It measures the antibiotic resistance and also used to inhibit microbial growth.
At the Point B, microbes can not grow in there; they are inhibited.
In the test, if bacterial strain or any other strain is susceptible to the antimicrobial agent, a zone of inhibition appears. If it shows resistance to that agent, then no zone is evidential.

How would you improve food safety from a food supplier standpoint (farmer, factory, production, distribution, food scientists) be very specific with your answer and make sure to use facts to justify why you believe the way you do. The explanation must be at least three paragraphs (5-8 sentences)
Answers
Answer:
Foods are the basic building blocks of living things, yet they may pose a threat and become harmful to human health in some situations [13]. Many people throughout the world become ill because of the food they eat. These diseases associated with food consumption are referred to as foodborne diseases, and they may result from dangerous microorganisms [14]. Foods can become harmful to human health or even fatal when combined with bacteria, mold, viruses, parasites and chemical toxins [13]. Therefore, it is absolutely necessary that consumers be provided with a safe food supply. The factors involved in the potential threat caused by foods are inappropriate agricultural practices, poor hygiene at any stage of the food chain, lack of preventive controls during processing and preparation of the food, incorrect use of the chemical materials, contaminated raw materials, food and water and inappropriate storage [15].

when muscles contract, the ____ energy of ATP is used to drive the ____ energy of contraction
Answers
Answer:
1. Chemical energy
2. Mechanical (kinetic) energy
Explanation:
The contraction of our muscles is accompanied by movement. Contraction of muscles involves the proteins myosin and actin, which forms a cross-bridge. Calcium ions bind to troponin protein allowing the myosin to bind to the binding sites on the actin protein.
However, for this cross-bridge cycle between myosin and actin to occur repeatedly, ATP is needed to induce the release of the myosin from the actin active site. Therefore, When muscles contract, the CHEMICAL energy of ATP is used to drive the MECHANICAL energy (kinetic energy) of contraction.
NOTE: ATP supplies chemical energy to induce movement of muscles during contraction. Energy due to motion is called KINETIC ENERGY.
When muscles contract, the Chemical energy of ATP is used to drive the Kinetic energy of contraction ; The missing answers are ; Chemical and Kinetic
When we contrast our muscles ATP induces the release of myosin from its actin active site ( i.e. the use of the chemical energy contained in ATP ). the release of myosin leads to the contraction of the muscles, which is a form of mechanical/kinetic energy. The proteins involved in the contraction ( kinetic energy ) of muscles are myosin and actin while the calcium ion involved is troponin.
Hence we can conclude that When muscles contract, the Chemical energy of ATP is used to drive the Kinetic energy of contraction.

Water is essential for life. Its special properties make water the single most important molecule in plant life. Which of the following properties of water enables it to move from the roots to the leaves of plants?
Answers
Answer:
Because water exhibits cohesive behavior.
Explanation:
Cohesive behavior can be explained as a behavior where molecules are attracted to each other.
And this means that, water molecules are attracted to each other because of their cohesive behavior. This makes them to be attracted to other substances, such as the walls of the xylem of plants.
In this case, it is believed that the water molecules behave this way because they are polar, that is, there is an electronegativity difference between the bonded atoms. And this enables it to move from the roots to the leaves of the plants.

Explanation:
The zika virus was first identified in Uganda in 1947. The virus is transmitted from person to person by a bite from a mosquito. It is commonly carried by the Aedes mosquito which is prevalent throughout Central Africa. The virus has more recently spread to the Americas (South, Central, and now North) and is expected to spread to Europe. There is a concern that the virus may reach epidemic proportions. Zika virus is related to yellow and dengue fever. Common symptoms are low grade fever and a distinctive skin rash and other symptoms include vomiting, headache, and muscle and/or joint pain. Pregnant women should avoid traveling to areas known to have zika virus present because the virus is known to cause microcephaly and developmental difficulties related to the central nervous system. Based on the paragraph above, class discussions, and other VALID (be careful with your selection of e-materials! CDC – Center for Disease Control is a good place to start) sources of information please answer the following questions. State a reason why the virus has spread to the Americas and likely to spread to Europe. Define the term microcephaly. What bones of the fetal skull would be affected by zika? Specifically, what area of the CNS is not fully developed in microcephalic individuals. In 1 -3 sentences describe the developmental difficulties of microcephalic individuals. How does one know if they have contracted zika? Do men need to be concerned about contracting zika? How does one avoid contracting zika? In a short paragraph (2-5 sentences!) provide one example of a scientific measure that could possibly control the spread of zika and explain how the measure works (controls the spread).
Answers
Answer:
1.Most people infected with the Zika virus have no signs and symptoms, while others report mild fever, rash and muscle pain. Other signs and symptoms may include headache, red eyes (conjunctivitis) and a general feeling of discomfort.

Almost all of the children had prominent calcifications in the brain. Unlike in children infected with cytomegalovirus, periventricular calcifications are the exception in children infected with Zika virus. 3.No they should not be worried.

Why must a forensic anthropologist be able to distinguish between antemortem and perimortem pathology
Answers
Answer: Antemortem describes injuries or pathologies inflicted on the victim before the death. Perimortem refers to any injury associated with the manner of death.
Explanation:
A foresen anthropologist is a person who is dedicated to identifying and studying skeletonized human remains and trying to determine markings on the bones that can elucidate the causes of death. In this way, the anthropologist seeks to learn about the events that occurred by studying the injuries and analyzing evidence left at the scene.
The term antemortem is used to describe injuries or pathologies on the victim before his or her death, which, however, have not caused the person's death. On the other hand, the term perimortem refers to injuries or pathologies associated with the manner of death. That is, it is necessary to distinguish between the two to determine the cause of death of the person. Not only has an antemortem injury or pathology not led to death, but it has no relationship to the event. And a perimortem injury or pathology is fatal, it must be focused on in order to clarify the facts and know how the person died.
Confusing an antemortem pathology with a perimortem one or vice versa, can lead to an erroneous diagnosis of the cause of death.

2. Sugar dissolves in water, but is not an ionic compound. What does this tell you about sugar?
3. Water is used in the cells to help transport in the chemicals necessary to survive. Since cell membranes need to be able to hold in and hold out water without dissolving, what do you suspect cell membranes are made from? Why do you think this?
4. Remember "The Wicked Witch of the West" from The Wizard of Oz? She melted when doused with water. What do you think her cell membranes were made of, and why?
5. Find out why hot water freezes more quickly than cold water, and explain it here.
6. Explain why heavy water is heaver than regular water.
Answers
Answer:
Kindly check explanation section.
Explanation:
So, let us dive straight into the solution to this particular Question or problem. We are asked to explain the phenomenon in each case.
(1). Expansion occurs at the surface of a pond water when it freezes at 0°C thus creating higher density for the (liquid) water at below the iced surface.
(2). When sugar is put in water it does not ionized but only dissolved as a molecule, therefore, sugar is a weak electrolyte.
(3). Cell membranes are made of phospholipids and proteins because phospholipids as far will not want to mix with water, also movement of molecules is done by the presence of protein.
(4). The witches cell membranes does not have phospholipids which makes it to have little adhesion force and this was the prime factor in the dissolving of the witch by water. The cell membrane contain nonfatty components.
(5). The statement is true, and this is a phenomenon refer to as the Mpemba effect that is to say when one cools down hot water it looses some of it mass(reduces the quantity of water) and this is due to evaporation. Thus, as the quantity of water reduced, freezing becomes faster.
(6). Heavy water is D2O while normal water is H2O. Where D in D20 means Deuterium which is heavier than Hydrogen atoms in heavy water.
