Explanation:
Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein.
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>

Answer:
Like the plasma membrane, organelle membranes function to keep the inside "in" and the outside "out."
Explanation:
Answer:
One offspring would have red leaves.
Explanation:
Given
Yellow leaves are dominant and red leaves are recessive
Let us assume that the trait of Yellow color of a leaf be represented by "Y"
and the trait of red color of a leaf be represented by "y"
When two parent of genotype "Yy" are crossed with each other, the following offsprings are produced as shown in the punnet square below
Y y
Y YY Yy
y Yy yy
Total four offpsrings are produced out of which only one has red leave as red color is a recessive trait and it will appear only when both the allele in a cell are of red color.
Thus, one offspring would have red leaves.
