Most important and abundant one are the phospholipids - amphiphatic molecules with an hydrophilic head and a hydrophobic hydrocarbon tails. They compose the membrane bilayer. Also important are the membrane proteins, which can be periheric and internal and can serve as channels, receptors, pumps etc.
Depending on the cell type the membrane can also contain cholesterol (in animal cells, enhances the membrane stability) or hopanes(in prokaryotes, same function as cholesterol) or ether-phospholipids with branched hydroharbon tails(in archaea, make the membranes more stable and resistant to severe conditions, as archaeas are extremophiles)
Answer:
C. The moon's gravitational pull and Earth's rotation
Explanation:
The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.

Herpe simplex virus
Herpes simplex viruses can
also be refers to as human herpes virus 1 and 2 and these virus commonly spread

is made up of double stranded linear DNA genomic enclosed within an icosahedral
protein called the capsid. Thus, there production is triggered by the development of emotional or phycological stress by the host.
