Answer/Exlanation:
1) ATP (adenosine triphosphate) can be hydrolyzed such that it loses a phosphate group to form ADP (adenosine diphodphate). This is called ATP hydrolysis. This property allows ATP to act as energy currency because ATP hydrolysis releases the energy stored in the high energy phosphate bond.
2) Transporting molecules against their concentration gradient requires energy. When ATP loses its phosphate group, it can phosphorylate another molecule. This converts the molecule into its active state, giving that molecule the energy to pass through against the concentration gradient.
1) The ability of the ATP compound structure to act as an energy currency has been explained in the answers.
2) The method used by ATP to allow protein transport molecules against their concentration gradient has been explained below.
1) ATP is an acronym that stands for Adenosine triphosphate. This compound called ATP is divided into three phosphate groups with phosphate bonds that possess very high energy. Now, when water is added to ATP, the phosphate bonds that possess high energy will be broken down thereby releasing energy and producing adenosine diphosphate (ADP).
2) We saw above that when ATP undergoes hydrolysis, the phosphate bonds are broken down to form ADP and releases energy. However, it can undergo further phosphorylation to form another molecule which becomes energized when it goes to a higher energy state.
Now, In this higher energy state it gets to, it will be observed that the protein will possess enough energy to transfer molecules against a concentration gradient that requires energy.

how might toxicology be important to other biomedical professions outside of forensics?
Answer: See explanation
Explanation:
Toxicology is a field in science that has to do with the effects of poisons, toxics and how they can be treated. Through toxicology, one can understand how harms are caused by chemicals and the health of the public can be protected.
Toxicologists study chemicals, drugs and other substances, and looks at how safe they're and their impact on living organisms. Toxicologists help in the development of methods that'll be used to know the harmful effects and the the dosages which causes it.
Furthermore, toxicology gives vital information and knowledge which the decision makers or regulatory agencies
in other biomedical fields can use in order to put programs in place that can be used to limit the exposures of humans to the substances.
In conclusion, less exposure to these substances is vital so that diseases can be prevented.
Toxicology is also used in the field of environmental health.

Are fully functional structures in a species.
Are usually present, but are no longer functional.
Have been completely eliminated from the species.
Answer:
Are usually present, but are no longer functional.
Explanation:
Vestigial structures are "evolutionary remnants". They are anatomical features that were once important throughout the organism's evolution, but now have no function. However, they aren't harmful either, so there has been no selective pressure for them to be removed via evolution.
Good examples in humans are the tail bone, wisdom teeth, and the appendix.

You are cleaning your room, when all of a sudden the smoke alarm goes off. You go into the kitchen and it is very smoky, so you inhale smoke. Your body has to immediately get rid of the carbon molecules you just inhaled. Explain all the parts of the cell involved in getting the smoke out of your cells.
Answer: The smoke goes to the cells of the mouth or buccal cavity, nasal cavity, trachea, larynx, and then finally distributed into the bronchi (small tubes) in the lungs.
Explanation:
Respiratory system can be defined as the complex system of organs that allow us to obtain oxygen for biochemical oxidation of food and releasing energy in the form of ATP. The breathing is a process in which the air is inhaled inside the respiratory system and oxygen is absorbed by the cells and carbon dioxide is expelled out of the body. The pathway of oxygen is cells of the mouth or buccal cavity, nasal cavity, trachea, larynx, and then finally, distributed into the bronchi (small tubes) in the lungs and it is reverse for carbon dioxide or carbon monoxide gas components present in the smoke. The red blood cells are the cells that are involved in getting rid of smoke out of the body, as they have hemoglobin which has binding efficiency with both oxygen and carbon dioxide. The exchange of deoxygenated blood (carbon dioxide containing blood) takes place in the blood capillaries. From the blood capillaries the carbon dioxide is expelled out from the bronchi following the entire route of expiration.

Answer:
They need food in order to gain the initial energy they need.
Explanation:
Plants unlike humans don't get food by primary sources (aka, hunting). instead they retrieve their food from the suns rays. Without the suns rays they are able to convert this energy into glucose for themselves, and will essentially die because they do not have that source of food to give them the energy they need to survive.

The phenotype of an organism ?
- represents its genetic composition.
- occurs only in dominant pure organisms.
- cannot be seen.
- reflects all the traits that are actually expressed
HELP PLEASE
Answer:
The phenotype of an organism reflects all the traits that are actually expressed.
Explanation:
Phenotype refers to the visible or evidentiable characteristics that depend on the genotype, which is stored in the DNA. Phenotypic expression, mainly determined by genes, also depends on the influence of the environment on the individual.
Although the phenotype expresses characteristics such as skin, eye and hair color, height or shape of the nose, some characteristics are not entirely visible, such as specific functions or synthesized proteins.
The other options are not correct because:
