Answer:

p53 gene is an important gene that regulates the proper functioning of the cell. This gene plays an important role in the cell cycle progression and acts as genome guardian.

Any mutation in p53 leads to the formation of the different types of cancer cells. The p53 gene is activated by teh phosphorylation at the particular sites.  High levels of phosphorylated p53 in the cell indicates that the cells DNA is highly damaged and mutated.

Answer:

Her minimum height must be 5'5" and her minimum weight must be 150 lb

Explanation:

The double red program is a program where red blood cells are donated by people . This red blood cells are used for treatment of patients that require red blood cells such as transplant of organs, transplant of tissues, treatment of cancer e.t.c.

Apheresis is a process whereby blood is collected or removed from the body and it undergoes the process of filtration into various components of the blood.

The machine that is used during apheresis collects the human blood and separates it into white blood cells, red blood cells and platelets.

lora16 [44]

Answer:

The claim by the researcher is supported because of the known functions of insulin and growth factors. Both hormones have a tendency to respond to the presence of glucose. The growth hormone initiates STAT5 signaling for producing the Igf-1 factor that is important for utilizing glucose. The insulin hormone is well known for utilizing glucose.

The rate of O2 production by the light reactions varies with the intensity of light because light is required as the energy sour
kupik [55]

Answer:

The correct answer is option a.

Explanation:

Yes, the light reactions also depend upon the Calvin cycle. Calvin cycle refers to a phenomenon that is used by the plants and algae to convert carbon dioxide from the atmosphere into sugar, the food needed by the autotrophs in order to grow. The plants rely upon the Calvin cycle for food and energy.  

In the given case, the rate of oxygen production would get diminish as the rate of ATP and NADP+ generated by the Calvin cycle diminishes. Of all the outcomes of the Calvin cycle, ADP and NADP+ are the only ones that get utilized by light reactions.  

The ADP and NADP+ are used up by the light reactions to fuel their reactions. This illustrates that if the rate of ADP and NADP+ generated by the Calvin cycle diminishes the production of oxygen by the light reactions also diminishes.
