When natural waters become overloaded with plant nutrients, such as nitrates and phosphates, they become _______________.

Answers

Answer 1

Answer:

Eutrophic.

Explanation:

Eutrophication is defined as the when natural water becomes overly enriched with nitrates and phosphates containing fertilizers, and detergents which induced excessive amount of algae in water. The process of eutrophication may result in water body oxygen depletion.

Example of eutrophication are algal bloom, and great increase of phytoplankton population which increased levels of nutrients in water body.

A population is made up of individuals where 149 have the A1A1 genotype, 18 have the A1A2 genotype, and 154 have the A2A2 genotype. What is the allele frequency of A1? Answer to 2 decimal places.

Answers

In population individuals where 149 have the A1A1 genotype, 18 have the A1A2 genotype, and 154 have the A2A2 genotype, so the allele frequency of A1 is 0.49.

What is the allele frequency?

The incidence of a gene variant within a population is represented by the allele frequency. Alleles are different versions of a gene that share the same genetic locus on a chromosome.

To determine the allele frequency of A1

There is the formula:

frequency of A1 = (2 x number of A1A1) + Number of A1A2/ 2 x population

so, A1A1 = 149

A1A2 = 18

Population = 149 + 18 + 154 = 321

The frequency of A1 = (2 x 149) + 18/ 2 x 321

hence the frequency of A1 = 0.49

Therefore, the allele frequency of A1 is 0.49.
