Most bacteria live in a solution that is hypotonic relative to the cytoplasm of the bacteria. This means that the bacterial cell is constantly taking in water. The cell wall of a bacterium is a peptidoglycan polymer that is tightly cross-linked. This would therefore function to:_________-.
A. regulate the flow of most molecules into and out of the bacterial cell.
B. provide a rigid wall that prevents the cell from swelling.
C. provide a rigid wall that prevents the cell from shrinking.
D. confirm a close relationship to plant cells that have a similar structure and live in hypotonic solutions.
E. make all bacteria fairly uniform in metabolic chemistry.
Answer:
B. provide a rigid wall that prevents the cell from swelling.
Explanation:
When organisms are present in hypotonic surroundings, their cells that are in contact with the surroundings tend to gain water. Bacteria present in hypotonic solution would gain water as their cells are hypertonic than the surroundings. The entry of water would increase the volume of cytoplasm and could lead to the bursting of the cell. However, the presence of a cell wall made up of cross-linked peptidoglycan prevents the swelling of the bacterial cell and allow them to survive in hypotonic surroundings.

<em>Answer: Mitochondria are found in all body cells, with the exception of a few. There are usually multiple mitochondria found in one cell, depending upon the function of that type of cell. Mitochondria are located in the cytoplasm of cells along with other organelles of the cell.</em>
Answer:
yes
Explanation:
1. shows the type of person they are more than the interview can, if they're the type to post party pics or family pics says a lot.
2. it's public so they have the right.
3. a good employee shouldn't have anything to hide.
idk another 2 reasons why lol but theres 3
