Answer:

50% (Answer Choice 3)

Explanation:

One important thing to keep in mind when solving sex-linked Punnett Squares is that males can never be carriers, since they have one X and one Y chromsome. Thus, it is only possible for females to be carriers, because they have two X chromsomes. Because of this, before solving the problem, you already know that 50% or less of the offspring can be carriers, thus eliminating two answer choices right off the bat. Now, the only way to find out whether 25% or 50% of the offspring are carriers is to solve the Punnett Square. The two female genotypes resulting from the cross is X^{C}X^{c} and X^{C}X^{c}. Since both offspring have only one allele for color-blindness, both are carriers, which means that the answer is 50%.

Similarities:

Both involve ion movement. Both use ion channels to move ions across the cell membrane, in or out of the cell.

Differences:

Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.  Active Transport uses an ion pump (or Sodium/Potassium pump) to move 3 sodium ions out of the cell and 2 potassium ions in to the cell through the energy of 1 ATP molecule.  

In active transport particles move against a concentration gradient and therefore require energy which must be supplied by the cell. Carrier proteins that are found in the cell membrane of cells use energy to transport molecules or ions across the membrane, against the concentration gradient.

Passive transport is a naturally-occurring phenomenon and does not require the cell to exert any of its energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration.

Patel and her siblings try to stick to a low salt diet since they have inherited high blood pressure from their mother. This is
garri49 [273]

The low salt diet is a great solution to overcome heath determinant of Biology and genetics.

  • According to this question, Patel and her siblings have inherited high blood pressure from their parents. This tells us that the health condition is a genetic disorder, which is branch of Biology.

  • Patel and her siblings are however, on a low salt diet as a solution to overcome the health challenge (high blood pressure).

This solution is, hence, a great solution to overcome the heath determinant of Biology and genetics.

Describe why biodiversity increased with the introduction of sea otters in California over the last fifty years
Leya [2.2K]

Sea otters affected biodiversity because they control the populations of sea urchins, which endanger kelp forests. Kelp forests are important because they convert sunlight to living material, and they also provide food and habitat to sea creatures. Kelp is important in sustaining the diversity of ecosystems. Additionally, sea otters may also be accountable for the large size of abalones in California.
