The cell membrane (plasma membrane) is describe as a highly selective barrier composed of a lipid bi-layer. This structure plays an important role in moving molecules across the cell membrane in order for the cell to maintain homeostasis. If the cell is unable to take in the materials it needs or remove what it does not need, the cell may die. This inability of cells to maintain homeostasis may cause sickness or even death of an organism. Why is it important that the cell membrane is highly selective?

Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. ... Movement across a selectively permeable membrane can occur actively or passively

Explanation:

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
