Explanation:
Surface area and pores play important roles in the cell.
Pores are the tiny holes on the surfaces of a body. They help to facilitate movement of materials in and out of the cell.
The surface area is the amount of space the surface of a cell occupies.
- Pores in a cell needs to be in proper shape in order to facilitate movement of materials.
- When the pores in a cell are too large, too much materials are bound to leave the cell. Tiny pores makes it difficult for the cells to have enough materials to function properly well.
- The surface area of a cell allows for the diffusion of materials in and out of cell.
- The larger the surface area of a cell, the more and better reactions takes place because they will receive important life sustaining resources.

Sister chromatids have different alleles although carry same genes on same loci. So if it doesn't happen so, like if there are same alleles on sister chromatids then there is a problem in its formation. i.e., male and female alleles haven't contributed equally ( may be an error during their segregation process ). And obviously it doesn't happen in a real cell so we must understand this point. Because normally whenever it happens there's one half from the male and one half from the female. (i.e. maternal and paternal alleles contribute equally).
I hope you get the answer!!!
Answer:
A) Faster blood flow: A faster blood flow means the heart pumps blood with more power. Pumping blood to fast for too long can damage the heart muscle and interfere with its normal electrical signals, which can result in a dangerous heart rhythm disorder.
B) Infection: infection is caused by invasion of the body by external microorganisms. Disease can arise if the host's protective immune mechanisms are compromised and the organism inflicts damage on the host.
C) vomiting: This is an involuntary, forced expulsion of stomach contents usually through the mouth or nose. Body's reaction can be aspiration, electrolyte and water loss, damage to the enamel of the teeth, tear of the esophageal mucosa etc.
D) High blood pressure: This is due to the heart pumping blood at high pressure putting a strain on the walls of the blood vessels. In some cases, people with high blood pressure may have a pounding feeling in their head or chest, a feeling of lightheadedness or dizziness, or other signs.
All of the above is the answer
