Answer;
Amino acid side chains have many carboxyl and amino groups.
Explanation;
-A buffer solution is a solution that resists changes in pH when small quantities of an acid or an alkali are added to it. It is a chemical substance that helps maintain a relatively constant pH in a solution, even in the face of addition of acids or bases.
-Buffering is important in living systems as a means of maintaining a fairly constant internal environment, also known as homeostasis.Small molecules such as bicarbonate and phosphate provide buffering capacity as do other substances, such as hemoglobin and other proteins.
-
Protein buffer systems depend upon proteins, as opposed to nonprotein molecules, to act as buffers and consume small amounts of acid or base. Since amino acids have the capability of reacting with both acid and base, they naturally act as buffers.
Answer:Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes, function as energy storehouses, and function as important signaling molecules. The three main types of lipids are triacylglycerols (also called triglycerides), phospholipids, and sterols.
triglycerides- fat
phospholipids- plant and animal cell membrane
sterols- plant and animal cell membrane's microorganism.
Explanation:
serving size is a set portion created by the government. it is the optimal amount of food/liquids to be consumed by one person.
The data suggests that there is no change in height of sheep because of
Hardy Weinberg equillibrium.
Explanation:
Data given:
heights of 200 sheeps remains the same for two years.
reason=?
There is no change in the phenotype of the sheep population during two years as there is no effect of environmental factors, no evolution or genetic drift in the population. Such population happens due to Hardy Weinberg equillibrium.
This principle says that there will be no genetic variation in a population when no evolution causing factors are there. These factors are environmental, mutation, genetic drift, natural selection or gene flow. When no new alleles are added in the population it remains same.
Thus in case of the 200 sheeps it is assumed that they were in Hardy Weinberg equillibrium.
