Explanation:

What I got to have

Eutrophication (from Greek eutrophos, "well-nourished") is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients. It has also been defined as a "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication in freshwater ecosystems is almost always caused by excess phosphorus.

I hope this helps

A new kind of tulip is produced that develops only purple or pink flowers. Assume that flower color is controlled by a single-ge
g100num [7]

Answer:

Explanation:

the purple allele (C) is dominant to the pink allele (c).

The frequency of C represents p while that of c represent q. Using the formula p+q= 1

The proportion of pink flower is 153/1000 = 0.153. This is also the frequency of the genotype cc (q^2).

Thud to find q which is the frequency of the c allele,

q = √0.153

q = 0.3912

From the formula p +q = 1 we can find p p = 1 - 0.3912

p which is the frequency of the C allele

p = 0.6088.

B. the proportion of all purple flowering plants that are heterozygotes and homozygotes is 847 / 1000 = 0.847
