Answer:
The dentritic cells can sense all of the foreign patogens that can invade the body.
Explanation:
Once a patogen comes into the body, the dendritic cells will recognize this patogen and send the information needed to create the right antibodies to protect your body of this invader. Once this happens, the body can start working in an adaptive way, because, if you don't have the right antibodies for the invader, the DCs will need to warn the body to produce lots of different kinds of antibodies, and with that, try to adapt itself to the virus or bacteria.
Answer:
A hypertonic environment will result in cell shrinkage due to osmosis. However, this question is unclear because it's not the lack of water that causes shrinkage, it's the loss of cell water due to there being more concentrated aqueous particles outside of the cell vs. inside of the cell. I would still go with hypertonic though.
I believe the correct answer from the choices listed above is the third option. It is oxygen that is a necessary reactant for cellular respiration to occur. Cellular respiration, in a sense, is breaking down sugar in the presence of oxygen. Hope this answers the question.
The function of the nucleus is to control the other organelles. It also functions to contain the DNA of the cell causing the cell's behavior and actions. It's basically the "big boss" of the cell.
