Answer:
Yes you are correct.
Explanation:
Number one is the rough ER not the nucleus. Number 3 is the mitochondria not the Ribosomes. This is an animal cell so there can not be a cell wall. There are exactly 3 small vacuoles in an animal cell so yes, you are correct.
Because warm air rises up so it's warmer on the top floor.
Answer:
Cancer cells achieve proliferative immortality by activating or upregulating the normally silent human TERT gene (hTERT) that encodes telomerase, a protein with reverse transcriptase activity that complexes with other proteins and a functional RNA (encoded by hTR, also called hTERC) to make a ribonucleoprotein enzyme.
Explanation:
A rare cell that escapes crisis almost universally does so by reactivating telomerase and this cell can now become a cancer cell with limitless potential to divide. Almost all cancer cells have short telomeres and thus inhibitors of telomerase should drive such cancer cells into apoptotic cell death. Yet, each time a cell divides, the telomeres get shorter. When they get too short, the cell no longer can divide and becomes inactive or "senescent" or dies. This process is associated with aging, cancer, and a higher risk of death.

Neuroimaging or brain imaging is the use of various techniques to either directly or indirectly image the structure, function/pharmacology of the nervous system. It is a relatively new discipline within medicine, neuroscience, and psychology.
Answer:
For the first question I think it's C - The mRNA was not bound by a ribosome. I'm not 100% sure sorry if I'm wrong. I tried my best to figure it out.
Explanation:
For question two I think it's C- Replication replacing an amino group. I'm not 100% sure sorry if I'm wrong. I tired my best to figure it out.
