The Hardy-Weinberg principle is used to characterize the distribution of the different genotype frequencies in a population which are not evolving. In the Hardy-Weinberg equation,
the frequency of the homozygous dominant genotype is denoted by 
;
the frequency of the homozygous recessive genotype is denoted by 
;
the frequency of the heterozygous genotype is denoted by 2pq;
the frequency of the recessive allele is denoted by q;
the frequency of the dominant allele is denoted by p.
Answer:
a. derivatives of triacylglycerols that contain a polar phosphate head and an amino alcohol at one of the positions of the glycerol group.
Explanation:
Glycerophospholipids consist of glycerophosphate which is an ester of glycerol and phosphoric acid, long-chain fatty acids, and certain alcohols. The glycerophospholipids is responsible for the formation of cellular membranes of organelles within cells of all organisms. The name of Glycerophospholipids indicates the presence of glycerol, phosphorus and lipids so that's why we can say that it is derivatives of triacylglycerol that contain phosphate and an amino alcohol at one of the positions of the glycerol group.
For the first question, i think the correct answer is A. Normal cells undergo apoptosis while cancer cells don't. For the second question, The answer is option B.<span> </span><span>Cell division has two checkpoints namely, G1
checkpoint and spindle assembly checkpoint. The checkpoint which determines if
division has properly occurred is the G1 checkpoint. At this point, is a damage
in the DNA is detected or the has not reach the optimum size, the cell is
stopped in G1 and is not allowed to proceed to further process.</span>
