[Answer] The cell membrane around a cell forms a barrier that protects and regulates the cell. Certain chemicals can pass through the plasma membrane because they have similar chemical properties as the membrane. Which best describes those that can pass through?

Membrane potential (also transmembrane potential or membrane voltage) is the difference in electric potential between the interior and the exterior of a biological cell .For the exterior of the cell typical values of membrane potential normally given in units of milli volts and denoted as mV range from –40 mV to –80 mV.. All animal cells are surrounded by a membrane composed of a lipid …

Some cells in some multicellular organisms lack mitochondria (for example mature mammalian red blood cells).A number of unicellular organisms such as microsporidia parabasalids and diplomonads have reduced or transformed their …

Apoptosis (from Ancient Greek ἀπόπτωσις apóptōsis “falling off”) is a form of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes and death.These changes include blebbing cell shrinkage nuclear fragmentation chromatin condensation chromosomal DNA fragmentation and global [vague] mRNA decay.

The cell envelope is composed of the cell membrane and the cell wall.As in other organisms the bacterial cell wall provides structural integrity to the cell . In prokaryotes the primary function of the cell wall is to protect the cell from internal turgor pressure caused by the much higher concentrations of proteins and other molecules inside the cell compared to it…
