Answer:
The correct answer is option sebaceous glands.
Explanation:
The dermis layer has two glands sweat and sebaceous glands. Sebaceous glands are associated with skin hair follicles and produce a lipid-rich substance having minerals and proteins.
Sebaceous glands also assist the skin to inhibit or protect from microbial growth due to the presence of some fatty acid and lipids.

Answer:
0.1460
Explanation:
Total population size= 411 + 911 + 800 = 2122
Let's assume that the population is in Hardy Weinberg Equilibrium.
Under these conditions, frequency of recessive allele (a)= 911 x 2 + 800 / 2122 x 2 = 2622/4244= 0.6178
.
This is because each homozygous recessive genotype has two copies of the recessive allele while each heterozygous dominant genotype has one copy of the recessive allele.
For this population to be under Hardy Weinberg Equilibrium, frequency of dominant allele (A) = 1- 0.6178= 0.3822
Frequency of homozygous dominant genotype (AA) = 0.1460
The combination of drought and poor land use practice created the the dust bowl.
