The major difference between bacterial and eukaryotic cytoplasmic membranes is the presence of <u>nucleus</u><u>.</u>
Nucleus are molecules that are typically found in eukaryotic cytoplasmic membranes but lacking in bacterial cytoplasmic membranes.

Answer:
Evolution takes place every generation of a species. The more rapid a species procreates the quicker it can respond to percieved threats & challenges in its environment. This is why insects, rodents, bacteria, and viruses can more readily adapt to chemical sprays or agents that are used to kill it. Mosquitos and DDT are such prime example of adaptation; mosquitos that survived DDT became more immune to its effects through genetic changes for each generation exposed.
Explanation:
When the upper water layers warm in the summer months, they become separated from deep water by a transition zone known as a thermocline. In a thermocline, the temperature decreases rapidly with small increases in depth. This phenomenon linking temperature change with depth is called temperature stratification.
Answer: 1. Phosphatidyl serine: the phosphoserine group
2.Sphingomyelin: the phosphocholine group
3.Cholesterol: the hydroxyl group
4. Triacylglycerol: the ester bond between glycerol and fatty acids.
Explanation:
Amphipathic molecules have parts that are hydrophobic and hydrophilic. The cell membrane is made up of amphipathic molecules.
Phosphatidyl serine has a polar (hydrophilic) head named the phosphoserine group, the fatty acid group forms the chain.
Sphingomyelin consist of phosphicholine and ceramide. The phosphocholine group is the hydrophilic part while the ceramide is the hydrophobic part.
Cholesterol contains a hydroxyl group (-OH) that is polar while the rest part of the cholesterol is non polar.
Triacylglycerol is made up of glycerol and 3 fatty acid chains. The ester bonds between glycerol and the fatty acids is the Polar part of triacylglycerol.
