Answer:
Both natural selection and genetic drift are mechanisms for evolution (they both change allele frequencies over time). The key distinction is that in genetic drift allele frequencies change by chance, whereas in natural selection allele frequencies change by differential reproductive success.
Answer: A line graph would be the best graph to show trends in data
Explanation:
Usually, only mammals undergo Carnegie stages.
Therefore, 'B. Sheep' would be the correct answer.
Answer: Energy is stored in the body primarily as GLYCOGEN in the muscles and liver and as TRIGLYCERIDE in subcutaneous body fat.
Explanation:
We take in food for the purpose of ENERGY, building of worn out tissues of the body and to boost the body immunity. After the intake of food, amino acids from dietary protein are used to synthesize body proteins and other molecules, carbohydrate is used to maintain blood glucose and to build glycogen stores, fat is used for energy or stored in the body.
The body must have a steady supply of energy with some of it coming from the metabolism of glucose.
GLYCOGEN formation occurs when there is excess blood glucose level in the process called glycogenesis. It is the suitable way glucose can be stored as it is insoluble and can not disturb the osmotic pressure of the cells. When food is restricted over time, glycogen stores are expended, and the body must rely on the breakdown of stored GLYCOGEN to be converted to glucose for energy production.
Also, energy for tissues that don't require glucose can come from the breakdown of triglycerides in the adipose tissue. TRIGLYCERIDES are formed by the liver when excess calories are taken, and are stored in the adipose tissues.
<u>Answer</u>:
Neutral molecules are the products of the hydrolysis reaction.
<u>Explanation</u>:
Hydrolysis reactions are double decomposition reactions. In these reactions water reacts to the ester linkage in a molecule resulting into the breaking of bond between the elements of the molecules.
The products those result include the one which receives the hydroxyl (OH) group from the reacting water molecule and another one receives the remaining proton (H+). For example, if AB is a compound in which A and B are atoms or groups after the hydrolysis reaction with a water molecule (HOH) the products of this reaction may be the neutral molecules represented by the given reversible chemical equation i.e. AB + HOH ⇌ AH + BOH.
