Answer: Upwelling

Explanation:

Upwelling is a process of movement of dense, cold and nutrient rich water from the bottom of the ocean to the surface layers due to wind currents. This process replaces the warm and nutrient deficient water from the surface.

This process is useful for the growth of phytoplanktons and other sea plants growing in the surface layer of oceanic water.

For each population description, identify which Hardy-Weinberg assumption is violated?
zavuch27 [327]

Answer:

4. A large and isolated population of squirrels in a relatively stable environment in which no genetic mutations are occurring and mating between males and females is random.

Explanation:

1. A small and isolated population of seals living in a stable environment with no genetic mutations.❌

1. false

Hardy-Weinberg assumption is not violated for a small population as seen in this case.

2. A large population of fish where females mate with males based on size.❌

false

Hardy-Weinberg assumption is not violated for an instance where mating is not random as seen in this scenario.

3. A population of birds with no genetic mutations that often mate with members of neighboring bird populations.❌

False

Hardy-Weinberg assumption is not violated for where gene flow is seen among population in this scenario.

4. A large and isolated population of squirrels in a relatively stable environment in which no genetic mutations are occurring and mating between males and females is random.✔

True

Hardy-Weinberg assumption is violated for in this situation due to large population size.

5. A small population of spiders living in an environment that strongly favors larger individuals.❌

false

Hardy-Weinberg assumption is violated for a small population and natural selection occurring as its obvious in this case.

There are five primary Hardy-Weinberg assumptions:

A. no mutation,

B. random mating,

C. No gene flow,

D. infinite population size,

E. No selection.

If the assumptions are exempted in a gene, the population of that gene might undergo evolution causing a resultant change in the gene's allele frequencies.
