Which of the organelles in the animal cell is involved in exocytosis?

Answers

Answer 1
Answer:   Golgi Body. 
It's essentially the processing center of the cell. Products enter through the Cis end and exit through the Trans end in vesicles. The inside of the vesicles have the same glycoproteins, carbohydrates, etc as the outside of the cell, so when the vesicle reaches the membrane it can open up, release its product, and become part of the membrane.

Unlike red blood cells, white blood cells A. can live for many years.
B. carry oxygen through the body.
C. are the most numerous cells in the blood.
D. are made in the bone marrow.

Answers

Answer;

A. can live for many years.

Unlike red blood cells, white blood cells can live for many years.

Explanation;

-Blood has four main components: plasma, red blood cells, white blood cells, and platelets.

-Red blood cells live for only about 120 days. As they wear out and age, they are captured and disposed of by cells in the spleen and other organs.

-White blood cells are different from red blood cells in several important ways. Unlike red cells, white cells are complete cells. They are larger than red cells and have a nucleus. White blood cells are not just carried by the blood stream, they can also move about independently. Additionally, Unlike red blood cells, white blood cells can live for many years.
The answer is neither of the above. All the above features except A relate to the red blood cells. (A is not true for both red blood cells and white blood cells.)Red blood cells or RBCs carry oxygen, are the most numerous cells (36 - 50%) in the blood and they are made in the bone marrow. The life span of RBCs is 120 days or 4 months.On the other hand, white blood cells or WBCs produce antibodies to develop immunity against infections and some are phagocytic against pathogens. They make up about 1% of the blood and are produced in the thymus. The lifespan of WBCs is 4 - 30 days.
