goblinko [34]

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

1. Explain why some heterotrophs can be described as both a primary consumer and a secondary consumer. What are these heterotrop
ExtremeBDS [4]

Answer:

Heterotrophic species that eat organisms from different trophic levels

Explanation:

Humans are examples of primary and secondary consumers because we are able to eat different types of living forms, thereby acting in the food chain as primary consumers (eating plants) in certain conditions and as secondary consumers (eating animals) in different conditions. Many heterotrophic organisms act at different levels by feeding primary producers and primary consumers based on specific trophic strategies. In consequence, the classification between primary and secondary consumers is arbitrary since it varies according to the trophic strategy adopted by the organism.
