The correct answer is C) 70/x.
To calculate doubling time, rule of 70 formula is used. For this the annual growth rate of the population is required. In this question growth rate is given x. Thus, doubling time = 70/ growth rate.
Therefore, doubling time = 70/x.
I choose the option (4) chemical bond.
Glucose is decomposed to 2 pyruvate, acetyl-CoA, and then entering the TCA cycle. All the energy such as ATP, NADH, and FADH2 is generated from braking the chemical bond.
Blood is isotonic to cells in order to conserve the shape and structure of the surrounding cells.
- Isotonic solutions are solutions that have the same concentration of water on both sides of a cell membrane.
- In this case, the blood is an aqueous fluid that exhibits isotonic properties compared to its surrounding cells.
- Isotonicity enables the blood to transport oxygen and nutrients to the cells but simultaneously conserves the structure and form of these cells.
In conclusion, blood is isotonic to cells in order to conserve the shape and structure of the surrounding cells.

Answer:
Polygenic inheritance
Explanation:
Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.
