Phosphorus in rivers can lakes sinks to the bottom and over thousands of years becomes ______ again.

1 answer:

5 0

Your question isn't the most clear, but I think your answer is rocks, or more specifically phosphorous rich rocks because the phosphorous will mix with the sediments on the river's/lake's ground forming phosphorous rich rocks.

That means that It'll become a phosphate mineral and later become phosphorous again when the minerals weather.

Hope it helped,

Indicate which of the following are criteria for maintaining a Hardy-Weinberg equilibrium. If the criteria is required select 't

Paladinen [302]

Answer:

- Populations must be very large -True

- The frequency of all genotypes must be equal. False

- Gene flow from other populations must be zero. True

- Matings must be random. True

- There should be no natural selection. True

Explanation:

The criteria for maintaining a Hardy-Weinberg equilibrium are:

Random matings: mating probabilities between individuals with determined genotypes depends on the products of frequencies of those genotypes.

No superposed generations: each individual can leave their gametes in the pool only once.

No mutations: There is no incorporation into the genetic pool of new gametes originated by mutation of preexistent alleles.

No migration: There is no incorporation of gametes originated in another population.

Infinite population size: the probabilities of randomly taking an A gamete from the pool are p and the probabilities of taking a B gamete from the pool are q.

No natural selection: Each individual has the same surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.
