Answer:
d. with just a few nights of sleep deprivation, but recovery will take more than a month of normal sleep
Explanation:
During sleep, the body heals itself, wear and tear of cells occur, and the chemical balance of hormones and neurotransmitters is restored. During sleep, the body prepares cytokines, that are protection and infection-fighting substances. Sleep deprivation prevents the production of cytokines and the ability to fight and prevent infections decreases. Sleep also enhances the T-cell responses which are associated with lymphocyte production pathway. Hence, people who remain awake have a lesser T-cell count due to decrease activation of T-cells. Hence, a few nights of sleep deprivation makes the immune system lack behind in the T-cell response generation. This low T-cell activity does not only impede the production of immune system cells but also reduces the functioning of existing cells such as decrease in cytokine functioning. Hence, the entire immune system cells needs a double amount of sleep functioning to keep track of immune system responses and rebuild the cells.
Well where is the work setting at? and does it affect the work you have to get done yes or no if yes then it creates a problem what did you have to do to figure out the edvidence that was hard and why did it make it hard sorry i couldn’t answer hope it helps

Answer:
I agree, They have been doing it..Im so lucky I never dowloaded the file and just reported them.
Explanation:
Mitosis is the nuclear division followed by cytokinesis, which leads to the production of two daughter cells.
<u>It includes the following phases -
</u>
1. Interphase - In this process the Cell actively metabolizes and prepare itself for the process of mitosis and the Chromosomes are not clearly discerned .
2. Prophase - In this phase , the Chromatin gets to condense and can be visualized under a light microscope and Nucleolus gets disappeared , Centrioles begins to move to opposite ends of the cell .
3. Metaphase - In this phase the Spindle fibers gets align the chromosome along the middle of the nucleus of the cell thereby creating a metaphase plate .
4. Anaphase - In this phase , the chromosomes which got paired up gets separate at the kinetochores and move to the opposite directions of the cell , the Spindle microtubules and physical interaction among polar microtubules is responsible for kinetochore movement.
5. Telophase - In this phase , the Chromatids completely move to the opposite poles of the cell , and new membranes start forming around the daughter nuclei and the Chromosomes disperse and become invisible. Cytokinesis starts.
6. Cytokinesis - In this final process the Actin fiber ring around the center of the cell contracts and create the cell into two daughter cells.
