Answer:
Some questions that can be asked:
1) How does the vaccine work and prevent diseases?
2) Can some people become allergic or have a negative response to vaccines, and How does this work?
3) What causes some vaccines to not work 100% effectively?
4) How do people create vaccines?
I'm not sure if this is what you were asking for, hopefully, this helps.
Answer & explanation:
Adenosine triphosphate (ATP) is a molecule made up of <u>one adenosine molecule</u> and <u>three phosphate radicals</u> (P) capable of storing small amounts of energy (from the breakdown of food) in their chemical bonds, acting as a temporary energy container.
ATP is directly linked to cell metabolic processes such as cellular respiration and photosynthesis. When cells need energy, for the sodium-potassium pump, for example, the ATP molecule breaks down.
This breakdown is made by hydrolysis (ATP breaks using water), so the bond between the phosphate group 2 and the phosphate group 3 breaks down, leaving one Adenosine diphosphate (ADP) molecule, which has two phosphate radicals.
At the end of the process the energy that kept the phosphate groups bound is released and used in processes such as <u>stretching and shortening of muscle fibers</u>, nerve impulses and hormonal regulation. These processes utilize the active energy released by ATP hydrolysis.
ATP - ADP conversion is the fundamental way to get energy because the cell cannot use the glucose molecule directly.
Answer:
Organisms use various strategies and adaptations to regulate body temperature and metabolism. The organisms control the exchange of heat by various ways which include physiological, behavioural means and by insulation.
The factors which play most important role in the heat exchange regulation between environment and organism are as follows:
- effective temperature difference between organism and environment
- Exposed surface area
- Evaporatory and circulatory changes
<u>Insulation</u> :Another most common method used for heat exchange.Animals who have furs,feathers and fat layers which play significant role in insulation. They are very much important because they reduce heat exchange amount between environment and organism. The most common example is of Cats. They used to curl up their bodies when they want to sleep in cold environment, they tuck their bodies in their paws and legs, and they wasp their tails around their bodies. When organism uses the food and oxygen the body temperature begins to increase, this method is known as metabolic heat production.
In prophase, DNA begins to cluster. In metaphase, two identical, condensed DNA strands line themselves up in the middle of the cell. After metaphase, there are: Anaphase, Telophase, and Cytokinesis. This process excluding or including Cytokinesis is called mitosis.
In the DNA replication for a cell baby, meiosis occurs.
