Answer:
Reduced penetrance or incomplete penetrance
Explanation:
Penetrance refers to the extend which a certain gene or set of genes is expressed in a population.
It can be complete where there is expression of the gene in a population having it.
Whereas, in reduced penetrance is where the mutation is not expressed in every individual in the population having it.
For instance polydactyly exhibits reduced penetrance since the parents had the mutation it was not expressed it came to be expressed on their pedigree.
Answer:
I believe the correct answer is both involve proteins in the cell membrane.
Explanation:
This is because Facilitated diffusion does not require any energy to transport molecules, while Active transport requires ATP. Facilitated diffusion transports molecules from an area of higher concentration to an area of lower concentration (or down a concentration gradient). Active transport moves molecules from an area of lower concentration to an area of higher concentration (or up a concentration gradient). Answer choice A is the only choice that makes sense.

Cells divide for many reasons. For example, when you skin your knee, cells divide to replace old, dead, or damaged cells. Cells also divide so living things can grow. When organisms grow, it isn't because cells are getting larger.
Grey seals breed in habitats where disturbance is kept to a minimal, like rocky shores, ice flows and islands. They feed on cold open waters. When pups are given birth in early winter or late autumn, their skins are white with yellowish tint. They are relatively helpless and rely on their mother's milk for the first few weeks after birth. They deposit a thick layer of blubber that will protect and allow them to adapt to the cold to sustain them when they will hunt for themselves. Hope this helps...
