Answer:A, B, C
Explanation:
A. The phospholipids are arranged in bilayers withe the Polar head groups oriented towards the extracellular side and the cytoplasmic side with a hydrophobic core.
The plasma membrane also contain membrane protein
B. Some Integral protein are Transmembrane protein the span the membrane and provide a hydrophilic channel and are selective for particular solute such as enzymes, antigens, hormones
The peripheral protein exit on the surface of the bilayer the serve as signal protein
C. The membrane lipid bilayers are not static or rigid. They show free lateral movement of its components hence the membrane is fluid in nature. Fluidity enables the membrane to perform endocytosis and exocytosis
Global and local climate change also makes marine ecosystems more vulnerable to lower oxygen levels (hypoxia). Aquatic organisms cannot survive without the presence of dissolved oxygen in the water.
When the climate is warmer, the surface water warms up more quickly and its density becomes lower than that of the underlying waters. However, it is the mixture of waters of different depths that helps to oxygenate the deeper waters. If the surface water is warmer and less dense, it mixes less well with the more dense bottom waters. As a result, the oxygen content will be lower in some places (deeper places for example).
At oxygen levels below 30%, species that do not tolerate hypoxic conditions must migrate to other geographic areas. If they can not migrate, their survival may be threatened.
Some of those lysosomes contain secretions that will help the immune cells destroy foreign pathogens.
Hope that helped you.
The protein would have the wrong shape.

D) areas at high latitudes
