<h2>Answer</h2><h3>A) Active Site.</h3><h2>Explanation:</h2>

An active site is a region that is present on an enzyme where the reactants or the substrate molecules we can say bind and experience a chemical reaction. The substrate is basically a reactant whose concentration is changing and that is converting into a product after binding at the active site of an enzyme. The active site usually has the residues that form bonds which are for the time being with the substrate are known as the binding site and the residues that catalyze a reaction of that substrate are known as the catalytic site.

A woman who is a carrier for colour blindness (X-linked recessive) has children with a man who has normal colour vision. A. What

viva [34]

Answer:

Explanation:

The Genotype of the woman is XCbXN

The man XNY

Since the allele for the color blindness is carried on one of the X -chromosomes of the carrier mother, then the male children will be color blind or carrier deopending on the defective gene they inherited. Since they will receive the defective or normal allele from the mothers,but the female will carriers or normal because they will inherit either defective allele or normal allele from the mother,but normal X allele from the father.

Assuming the colorbind gene was inherited by One of the boys, and the girls take the defective genes

1. XNY vs XCbXN.Then the one of the boys will be colorblind and the one of girls will be carriers. XNXCb, XNXN, XCbY,XNY 50 %

2.If the two boys take the effective genes from the mothers. and none of the girls take the defective alelle

Then the two boys will be colorblind and the girls will be carrries XcbY,XcbY and XNXN XNXN.(normal girls).

The proportions that will be the females since the girls can only take the defective allele from one of the normal and defective allele from the mother. Assuming the girls take the defective allele from the mothers and take normal from the father,they will all be carriers,since the X of the father is normal.

They can not have a color blind girl.Since the father is normal It takes two colorblind X-chromosome to give a girl.

Arrow symbol →

Explanation:

The arrow symbol in a chemical equation separates the reactants from products.

A chemical reaction is process in which chemical changes leads to the formation of products from reactants.

The arrow symbol → is used to separate the reactants from products

⇆ shows reversibility of the reaction

↑ indicates that gas is given off as product

10. If there are very few differences in the DNA of two different species, what can we infer about their relationship? For examp

Burka [1]

Answer:

Chimpanzees.

Explanation:

DNA sequence similarity is helpful to determine the evolutionary relationship between the organisms. The evolutionary tree can easily be constructed if the percentage of the DNA sequence similarity is known.

The human shows 98.8% sequence similarity with chimpanzee. The sequence similarity between human and gorilla DNA is 98.4%. This means Chimpanzee are more closely related to humans than gorillas.

Thus, the answer is chimpanzee.

Cellular respiration involves two phases. The anaerobic phase does not involve oxygen, while the aerobic phase does. Where does

Alex

While the majority of anaerobic (without oxygen) and aerobic (with oxygen) respiration occurs in the cytoplasm and mitochondria, respectively, of the cell.

<h3>What is cellular respiration?</h3>

The process through which food, in the form of sugar (glucose), is converted into energy within cells is known as cellular respiration. All kinds of cellular operations are then powered by the energy that is stored in ATP molecules.

There are three types of cellular respiration

1) Anaerobic respiration happens when there is no oxygen present.

2) Aerobic respiration occurs when there is oxygen present.
