Why is it important for the cell membrane to allow materials to enter and leave the cell
umka21 [38]
<span>Cell membrane needs to allow and exit the materials that enter the cell because the cell needs nutrients and these nutrients are converted into molecules that aid in many cellular activities like repair, divide and form structures and biomolecules.
Also to excrete wastes and other harmful materials for the cell.
This continues because the cell wants to attain homeostasis.

Homeostasis is the state where the internal and external part of the body maintains and establishes balance and equilibrium. This is achieved through cellular processes in the body, the integumentary system regulates the body temperature, the hypothalamus –hunger and thirst of the individual and other interrelated organ systems that make the body healthy and in the state of equilibrium. Now, when diseases or disorders appear they disrupt the organ systems in the body thus, causing imbalance state –high fever, inability to focus and etc.<span>

A mutation that causes production of a defective pilus in a bacterium will prevent __________.
daser333 [38]

Answer:

The correct answer is: Attachment.

Explanation:

  • Pilus are thread like structures which are present on the surface of the bacterial cell.
  • They are mainly responsible for attaching the bacterial cells to a substrate, for obtaining food or to an eukaryotic cell for the purpose of infection.
  • Pilus also mediate the process of conjugation in some bacterial cells.
  • Conjugation is a process by which genetic material or plasmids are transferred from one bacteria to another through a channel formed in between the two bacteria by the help of the pilus.
  • Pilus also helps the bacteria by preventing them from getting recognised by the immune cells in the host.
  • A defective pilus will affect all the above processes, resulting in death of the bacteria.
