Answer:

It is also referred to as the phospholipid bilayer or the plasma membrane, It helps cells maintain homeostasis, It is selectively permeable; that is allows some substances through but not others

Explanation:

a. I don't know how to explain other names for the cell membrane but they are it, as the cell membrane is a bilayer composed of phopholipids and it is also called a plasma membrane

b. The cell membrane has many structures on it that facilitate nutrient transport in and out of the cell (ex: protein pump). nutrients of higher concentrations would like to move through lower concentrations, and it achieves this by moving across the cell membrane in or out of the cell, maintaining homeostasis

c. Some substances such as NaOH use pumps on the cell to move in or out of it, it can't get in or out without using pumps since they are so big, so the cell can choose when the cell wants it's nutrients or if it dosen't

Martha has a widow's peak (dominant trait) and attached earlobes (recessive trait).

Martha's dad had a straight hairline (ww) and unattached earlobes (Ee, because she has the recessive alleles ee and both parents give us one allele).

This tells you that martha has a mother with at least one of both alleles dominant for widow peak and at least one recesive allele of attached earlobes

So, martha's alleles are: Ww and ee.

If she marries a man that is heterozygous for both traits (Ww and Ee) the probabilitys are

Ww Ee x Ww ee: WWEe, WwEe, wWee, and wwee
