Facts on sexual reproduction

Biology
1 answer:
snow_lady [41]3 years ago
8 0
During sexual reproduction, the genetic material of two individuals is combined to produce genetically-diverse offspring that differ from their parents. The fact that most eukaryotes reproduce sexually is evidence of its evolutionary success. In many animals, it is actually the only mode of reproduction.

EXTRA POINTS!!!! Cystic fibrosis is regulated by a recessive allele, c. Explain (do not just fill in the Punnet square below) ho
Debora [2.8K]
Here, Assume, the parents are normal means, they aren't diagnosed with that disease. Let the Genotype of Female parent is XcX, it means, she is carrier of that disease. and Let male parent has genotype XY, it means, he is normal.

Cross: Xc X     ×     X Y

F1 Offspring: Xc X, Xc Y, XX, XY

Here, Xc Y would be the child with that disease. As "Cystic Fibrosis" is a recessive disease, it will show in a male when there is 1 copy on either gene, but in female, she must have both genes.

Genotype of Child with Cystic Fibrosis:  Xc Y

Hope this helps!

Calculate the energy yield of glycolysis and cellular respiration per glucose molecule. Distinguish between substrate-level phos
Nesterboy [21]

<u>Answer</u>:

A total of 32 ATP molecules per glucose molecule is generated in cellular respiration and glycolysis. In substrate-level phosphorylation, ATP is generated from the coupled reactions whereas in oxidative phosphorylation ATP is formed by using the oxidized NADH and FADH cofactors. The energy for oxidative phosphorylation comes from the movement of proton to the matrix of mitochondria through ATP synthase.

<u>Explanation</u>:

Each molecule of glucose utilizes 2 ATP molecules and breaks down into 2 pyruvate molecules and generates 4 ATP from substrate-level phosphorylation and 2 molecules of NADH.

Pyruvate converts into acetyl Co-A and produces 2 molecules of NADH. In citric acid cycle, the 2 molecules of acetyl Co-A produces 2 molecules of GTP/ATP, 6 molecules of NADH, 2 molecules of FADH2.

In oxidative phosphorylation 1 molecule of NADH contributes to the production of 2.5ATP, FADH2 gives 1.5ATP. Hence the total production of ATP is 4 + 2 + 25 + 3 = 34 – 2 ATP (used early in glycolysis) = 32 ATP (net ATP production).

What is the difference between a subscript and a coefficient?<br><br> Science
Sindrei [870]

Answer:

Explanation:

Subscripts are numbers that come after a symbol and below. Subscripts tell you the number of atoms of that element. If an element does not have a subscript, then it is understood that the subscript is 1.
