Hey there! :D
Organization in organisms is like this:
cells => tissues => organs => organ systems => organisms
Since we are talking about a group of cells, this would be a tissue. Don't let the word 'function' confuse you. Tissues do functions as well as an entire organ or organ system.
It is helpful to use the flow chart when asked questions like these, so make sure to memorize it! It will be helpful in any level of science.
I hope this helps!

Cancer cells are the best target to amplify the most within first 2 hours. Highly oncogenic retroviruses are recombinants of viral and host genes.
Retroviruses are viruses with RNA rather than DNA in their genomes that infect cancer cells. Reverse transcriptase is an enzyme that is used to integrate into the DNA of the host cells. It is enhanced to a greater extent the more cell replication takes place. More retroviruses are then produced by the cell, infecting further cells. Many diseases, including AIDS and various types of cancer, are linked to retroviruses.
Low-incidence cancer-causing retroviruses lack inserted host information. Instead, it seems that they alter the expression of potentially carcinogenic host genes, which in turn results in cancer. Retroviruses incorporate proviral DNA into the chromosomal DNA of their host during the course of their regular life cycle. Integrations take place across numerous locations. Although most integrations are benign, some can cause cancer. Many of these seem to encode tyrosine phosphorylating protein kinases.

Answer:
B)the energy required
Explanation:
The difference between active and passive transport is in the amount of energy they both require.
- Active transport requires energy to move molecules such as ATP and ions against a concentration gradient.
- Passive transport moves molecules from higher concentration region to one with lower concentration without requiring energy.
Energy is the ability to do work. In passive transport, energy is not used. But in active transport, energy is required.
Answer:
To prevent or limit bacterial contamination of the collected blood
Explanation:
The first few milliliters of blood have been reported to have a high probability of bacterial contaminant from the skin. Several studies have shown that diverting the first 10 to 30 milliliters of blood from a donor into a special pouch is effective in limiting the chances of collected blood being contaminated with bacteria.
<em>Hence, the purpose of the procedure is to limit the bacterial contaminant that will enter the blood collection bag.</em>
C organs because molecules combine to form cells and organs combine to make organ systems
