Answer:
Assuming the dominant allele is represented as A, and the genotype as AA and the recessive as a, and genotype as aa; then the F1 will produce the offispring. Aa, Aa, Aa,Aa in ratio: 1:1:1:1:1
This shows the dominance of allele A.
However if two of the F1 generation are crossed then:
The F2 is AA,Aa,Aa,aa the phenotypic ratio is
3 ; 1
W<u>hile the Genotypic ratio is ratio;</u>
<u> 1AA : 2Aa Aa; 1aa(1 ;2;1)</u>
Explanation:
Cholesterol is one of the molecules composing the cell membrane. b) makes the cell membrane fluid at room temperature.
<h3>What is the role of cholesterol in the cell membrane?</h3>
The cell membrane is composed of two lipidic bilayers, cholesterol, proteins, and glucans incrusted in between.
Cholesterol is one type of lipid.
These molecules are incrusted in the membrane between the hydrophobic tails of lipids.
Their proportion on both sides of the membrane is almost the same.
Cholesterol is a significant molecule that contributes to the membrane fluidity, separates phospholipids, and interact with membrane proteins regulating in their activity.
The correct option is b). makes the cell membrane fluid at room temperature.
