Answer:
Phospholipid bilayer determinates which molecules can enter or exit the cell so its purpose is to be a checker in the middle. Cell membrane determinates the structure of the cell and it is the connection to the rest that happens in a cell.
Explanation:
Molecules can move in 2 ways: passive and active.
The only difference is the energy that is needed to do the movement.
In passive mechanisms, energy is not used, while in active transport, energy is needed. Diffusion or passive transport are moving the concentration from hight to low so the energy is not necessary. Active transport moves from low to a high concentration and it uses metabolic energy.
The white blood cell is called NEUTROPHIL. Neutrophils play important roles in the immune system; they move around the body via the blood stream and when they sense signals that foreign bodies are present, they move to the site of the infection and destroy them. They are among the first set of immune cells that defend the body against infection.

They will visualize how a dog would run around, and play fetch, etc.
Answer:
The red blood cells will shrink in size when water diffuses out of them.
Option A and C are correct.
<h3><u>Explanation:</u></h3>
The DNA is the genetic molecule of a cell in an organism that contains the genetic information stored in forms of genes. The genes are expressed by means of protein synthesis. The genes are formed of particular sequence of nitrogen bases that is called as codon. These codons are transcribed into particular amino acids. This process involves the participation of DNA dependent RNA synthase that produces the mRNA from the portion of DNA by means of transcription. The mRNA that is produced from the DNA is formed of complementary nitrogen bases from the DNA, just exception is that in RNA, thymine is replaced by Uracil. This process is known ad transcription.
