The correct answers are A. The cell membrane is very selective, D. The cell membrane is a protective layer surrounding a cell, and E. The cell membrane allows waste to leave the cell.

Explanation:

The cell membrane is a membrane composed of lipids and proteins that surround and define every cell. This membrane had an important role because it regulates the substances and particles that enter and exit from the cell. The cell membrane is very selective as just certain substance can go out an in; for example, the cell membrane allows oxygen to enter into the cell and waste to leave the cell as this preserves the balance in the cell and it is necessary. Moreover, the cell membrane protects the cell from outside isolating it and avoiding nocive particles enter. According to this, it is true this structure is very selective, it acts as a protective layer and also it allows waste to leave the cell.

10. Write the 2 Hardy-Weinberg equations. Use the equation to calculate the percentage of carriers of cystic fibrosis (a recessi
Firlakuza [10]

Using the Hardy-Weinberg equations, the percentage of carriers of cystic fibrosis is 8.19%.

<h3>What are the Hardy-Weinberg equations?</h3>

The Hardy-Weinberg equations describe the relationship between alleles in a population that is fairly constant.

The Hardy-Weinberg equations are given below as;

p^{2} + 2pq + q^{2} = 1 \\p + q = 1

q^{2} = 0.009\\q = 0.09\\p = 1 - 0.09\\p = 0.91 Hardy-Weinberg equations

Percentage of carriers = 2pq

Percentage of carriers = 2 * 0.09 * 0.91 * 100 = 8.19%

Therefore, the percentage of carriers of cystic fibrosis is 8.19%.
