Answer:
Body fat can be divided into two components:
Essential body fat: It is the minimum percentage of fat required by the body in order to function efficiently and to maintain a good health. It is usually stored in small amounts in muscles, internal organs, bone marrow as well as the central nervous system.
Storage body fat: It is also called non-essential body fat as it is not required for the basic functioning of the body. Excess of food or energy is stored in the form of fat around the organs (visceral fat) and beneath the skin (subcutaneous fat) in the body. It serves as the energy reserve and is used when the body's glycogen reserves are depleted.
Hence, the given statement is true.
Answer: Option B
Explanation: First we should understand the role of enzyme and acid here. Pepsin is an enzyme which will break down proteins into simple monomers (like amino acids). And, acid causes digestion which means it will break down the protein into its respective elements and compounds. Water will act as a control in this experiment.
Option B is correct because it has all three criteria- 1. Control [water + protein] 2. With enzyme [egg white + pepsin] 3. With acid and enzyme
So this will give us an idea whether pepsin alone is breaking down the protein or digesting it. And there would be difference in test tube B and C. So this will clear the difference.
Option A is incorrect because it has not mentioned any different test tube for checking what happened with the protein. And, Option C is incorrect because mass of egg white will remain same after digestion also.
When studying biology and involves more memorizing facts about organisms and how they live because
The answer is Dilutions
Bacterial culture is one of the laboratory examination that could be used to determine if a specimen contain bacteria. But it will hard to count the colony if the bacteria count is too high.
That is why the specimen of the culture need to be diluted to reduce the bacteria count of the specimen, so the result will be easier to count. The unit used would be colony forming unit(CFU) per milliliter.
