Give a scenario where a cell may need to perform a form of endocytosis
Elanso [62]
Endocytosis is the process where a cell imports large things into the cell. All forms of endocytosis are active, meaning the cell expends ATP while performing this process. Specifically, a style of endocytosis called phagocytosis involves a cell surrounding the target material with its cell membrane and encloses it while bringing it into the cell.  This enclosed membrane bound material then pinches off into a spherical 'vesicle'.  An example of this can be a cell importing a protein into its cellular space.

Doctors do not administer vaccinations to people who are too sick. Which best explains why?
4vir4ik [10]

Answer:

D, The white blood cells of sick people may not be able to efficiently handle the weakened or dead form of the pathogen.

Explanation:

Vaccinations are essentially just weak diseases we use to create antibodies so the body can protect itself from the full disease. If it sees it once, it can defend itself, is the theory. This is choice D.

  • Why not A: The weakened form will be attacked by the immune system, but maybe not enough, because the person is so sick that the immune system is busy elsewhere.
  • Why not B: The medication is not what combines with the vaccine to cause problems. It is the body being overworked.
  • Why not C: The digestive system isn't the issue. You don't eat diseases.
