Answer:
The correct answer is A. transplanted organs contain antigens that can trigger white blood cell activity
Explanation:
The body's immune system is designed to seek out and destroy any foreign object it finds in the body, such as a cold or flu virus - or a transplanted organ. The process of destruction of the transplanted organ is called rejection.Immunosuppressive drugs will be provided to prevent your immune system from damaging the transplanted organ. Organ transplants require the use of immunosuppressive drugs capable of controlling the immune response triggered by the presence of antigens foreign to the body itself. The group of immunosuppressants is made up of drugs indicated both in the prevention of rejection of the transplanted organ and in its reversal.
Answer:
The correct answers are A and B.
Explanation:
Pleiotropy is defined as "when a single gene affects two or more phenotypic characteristic of an organism.". Phenotypic refers to the traits that can be physically observed or measured in an organism, for example height, hair color etc. So the examples of pleiotropy in the given options are in A and B which describe situations where one gene affects two or more phenotypic traits.

Telomerase is found in fetal tissues, adult germ cells, and also tumor cells. Telomerase activity is regulated during development and has a very low, almost undetectable activity in somatic (body) cells. Because these somatic cells do not regularly use telomerase, they age.
If starch is not digested in the small intestine (as happens when a significant amount of starch is ingested at once), it travels through the digestive system and is fermented in the large intestine.
what are the function of starch ?
Starch is a complex carbohydrate that is kept as a reserve food supply in plants and is generated from glucose during photosynthesis in the green leaves.
It is present in root vegetables, beans, and whole grains. Starch breakdown produces glucose units, which supply more energy to complete metabolic activities than simple carbohydrates.
When the body requires it, it transforms it into glucose, and this glucose circulates throughout the body via the circulation, where it is taken up by cells and utilized as a source of fuel.

At the top of the body of a water, there is a lot of light from the sun, which also means a lot of solar energy. This allows for a fruitful photosynthesis.
In contrast, at the bottom of the water, there isn't as much, or sometimes any, sun light. Because of this the organisms at the bottom of the body of water
<span>D. must rely on other means than photosynthesis
