The answer is b
<span>1.Upper Epidermis – The upper surface of a leaf that protects the inner cells of the leaf. 2.Palisade Layer – Long, thin, tightly-packed cells where most photosynthesis takes place. 3. Spongy Layer – Loosely packed cells with many air spaces between them in order to allow carbon dioxide to pass among the cells and get to the chloroplasts. 4. Lower Epidermis – The bottom layer that protects the underside of the leaf and has many openings (stomata)</span>
Answer:
15.21 %
Explanation:
If we recall the basic formula of Hardy-Weinberg's equilibrium ; we have the following below:
p + q = 1
p² + 2pq + q² = 1
where;
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
Given that p= 0.68 and q = 0.39
the percentage of the homozygous recessive genotype (q² ) will be
(0.39)² = 0.1521
= 0.1521 × 100
= 15.21 %
∴ the percentage of the population that has a homozygous recessive genotype = 15.21 %

The skin is an example of a non-specific defense.
For example, bacteria or diseases have trouble entering a healthy person's skin because it is formed by closely packed cells with multiple layers and a substance called keratin that protects is.
On the other hand, the immune system is a specific defense mechanism.
When bacteria is able to enter the body in cases of fever for example, the immune system is activate and sends out protector cells such as the white blood cells to combat infection.
