The correct answer is A.

Animal cells do not have a  cell wall.

A cell wall is the rigid, outermost covering of plant cells and is made up of cellulose.  It is absent in animal cells. The cell wall is visible under a light microscope.

Animal cells are instead covered by a cell membrane. It is made up of lipids, proteins, and small amounts carbohydrates. It is a thin and delicate structure  that can only be seen using an electron microscope.

A client with colitis inquires as to whether surgery eventually will be necessary. when teaching about the disease and its treat
AlladinOne [14]
The correct answer is that "for most clients, surgery is recommended only if non-surgical treatments have been unsuccessful." This is because of the guidelines involving medicine and surgery as well as guidelines involving the treatment of colitis. The question should have specified what type of colitis is the patient having, whether infectious or autoimmune. In infectious colitis, then surgery almost has no role and medical treatment with antibiotics as well as supportive therapy and fluid replacement are the only ones needed. In autoimmune colitis such as Crohn's disease or ulcerative colitis, while immunosuppressor drugs may have a role, surgery may be the mainstay of treatment especially those who are at risk of malignant degeneration.

In the mentioned case, both the cells will start to perform replication of their DNA. In the case of G0, that is, the stationary phase, the mammalian cell can pass the restriction point with the supplementation of extracellular proliferation signal. While in the case of G1, which actually does not require any kind of external proliferation signal, as once the cell is in G1 phase, it is ready to go get the next phase. However, both the mammalian cells will cease or halt at G2 checkpoint.
