Answer:

False

Explanation:

Genetic variation is the difference in the sequence of DNA in the individuals of a population and a heterozygote has more genetic variation that homozygote person because heterozygote has two different alleles of a gene while homozygous individual have two same alleles.

Heterozygotes have advantage over homozygotes because it protects the individual from many genetical diseases and increase the genetic variation by increasing the gene pool in the population. So higher fitness results in more genetic variation in the population therefore the statement is false.

What term is used to refer to the many feeding relationships that are possible in an ecosystem
bekas [8.4K]

Answer:

Food web

Explanation:

In an ecosystem, the series of organisms that are connected to each other by energy and nutrient flow is called the food chain. One organism in a food chain derives the nutrition and energy from the preceding organism of the chain. However, most of the linear food chains are interconnected to form food webs.

Food webs are interconnected food chains that occur in nature since organisms derive their nutrition from multiple sources. For example, a grasshopper can feed on grasses and grain both. A bird can derive its nutrition from a grasshopper or grain. Likewise, an owl can feed on mice or grasshoppers. These multiple feeding relationships lead to the existence of food webs.

Greeley [361]

Answer:

8

Explanation:

The fly has only 3 pairs of somatic chromosomes, that means that only can combine 3 chromosomes. To calculate the combinations the exponential 2n it is used. In this case is 2 to the third power that is equal = 2 x 2 x 2 = 8

This fly also has a fourth pair, but this one is the sexual one, so the main function of this gene is to give the sex to the offspring.
