Answer:

The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).

Explanation:

There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.

The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.

For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.

  • <em>Other options, such as </em><u><em>an increase in food availability</em></u><em>, a</em><u><em> decrease in tuna fishing </em></u><em> or </em><u><em>a decrease in tuna predators</em></u><em>, are environmental factors that contribute to increased genetic variability.</em>

A science class is checking to see how much life exists in local streams. One of the students records that 20 amoeba were found
Naya [18.7K]
What this student is doing is collecting data. So, he wants to check how many life forms there are in the waters nearby. In order to do so, he has to take a sample, and look at it through a microscope so as to determine the number. So, he collected a sample which is his data. He is not drawing conclusions yet, but rather counting these organisms. He is not making a peer review - his peers aren't even mentioned here. He is not forming a hypothesis because he is just counting at this point.

Interstitial cells produce?
Elanso [62]

Answer:

The correct answer is option E (testosterone).

Explanation:

The interstitial cells or Leydig cells are the individual or group of cells present in loose connective tissues surrounding the seminiferous tubules.

They are usually active in the production of dominant sex hormones in males that is testosterone responsible for male secondary sexual characteristics.They produce hormones in the presence of luteinizing hormone (LH) and growth hormone released by the pituitary gland.

The high cholesterol content and crystals of Reinke make the leydig cells appear pale in color.

Thus, option E- testosterone is the correct answer.
