Answer:
When a red blood cell is placed in a hypertonic solution, it contracts as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.
The reason that blood cells change in size when placed in a solution with different salt concentration is due to the osmosis process. Osmosis causes solutions with high concentrations of salt to draw water from areas with low concentrations of salt.
There are some exceptions to this phenomenon. Blood cells can draw water and explode when placed in hypertonic solution on some special occasions. Some diseases affect the structural integrity of blood cells. Also, when human blood cells are exposed to temperatures close to freezing, they can draw water and explode.
Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, the kidneys function through the use of osmotic principles. The kidneys filter an animal's blood to remove excess salt and balance the amount of water
D is probably right cos you are comparing data
Cell membrane, Organells, flagella
Mitosis refers to the procedure of cell division, in which a cell goes through a carefully mediated nuclear division, which results in the production of two genetically similar daughter cells. The mitosis comprises five active stages, that is, prophase, premetaphase, metaphase, anaphase, and telophase.
In a single-celled species like an amoeba, it is the process of mitosis by which the cells reproduce. After undergoing through the five stages of mitosis, it is via the procedure called cytokinesis, the single cell dissociates into two similar cells, thus, completing the reproduction.
During injury, the process of mitosis takes place to substitute the damaged cells. This repair is mainly essential for the blood vessels and skin that safeguards the organs and muscles in the body. Mitosis also assists to substitute the lost blood via a wound.
Thus, if the process of mitosis would not take place, then the organism would remain a single-cell, asexual reproduction would not take place, and the tissues of the body would not be able to repair themselves.
