<h2>Answer is option "E"</h2>

Explanation:

  • Enzymes belong to the proteins category because enzymes are long chains of amino acids bound together by peptide bonds
  • Enzymes have a special marker on them called an active site that, like a puzzle piece, fits with only one other type of molecule, generally referred to as a substrate. The substrate is a molecule that will undergo a reaction that results in it splitting into two separate molecules, called products
  • The substrate-specific to a particular enzyme will bind at the active site, forming what is known as an enzyme/substrate complex. In other words, a complex formed by the union of the enzyme and substrate
  • Hence, the right answer is option E "both A and B"

Serena is mixing a material into a beaker filled with a liquid. She notices that the material seems to disappear into the liquid
Lelu [443]

Answer:

The correct answer is - solubility

Explanation:

Solubility is the nature of the material that is a chemical property of that specific solute ability to dissolved in a solvent. The ability of solute or material in a solvent or liquid is measured by the term of the maximum amount of that material dissolved in the liquid at equilibrium.

Sugar and water is a great example of solubility. When sugar is missed in the water it dissolved in water and disappear in the water here sugar is solute and water is solvent.

Thus, the correct answer is - solubility.

In humans, the eye color and hair color genes are located on different chromosomes. Brown eyes (B) are dominant to blue (b), and
Andrej [43]

Answer:

Man's genotype: Bbdd

Woman's genotype: bbDd

First child's genotype: Bbdd

Second child's genotype: bbDd

Explanation:

This is a dihybrid cross involving two genes; one coding for eye color and the other for hair color in humans. The allele for brown eye (B) is dominant over the allele for blue eyes (b) in the first gene while the allele for dark hair (D) is dominant over the allele for red hair (d) in the second gene.

According to the question, A man with brown eyes and red hair will possibly possess genotypes: BBdd or Bbdd while a woman with blue eyes and dark hair will possibly have genotype: bbDD or bbDd. Considering the fact that they produced children with recessive traits for both gene (blue eyes and red hair), it means that they are heterozygous for their dominant trait. This means that the ideal genotype for the man is Bbdd since he will produce gametes containing B and b alleles for the first gene while the ideal genotype for the woman is bbDd since it will produce gametes with D and d allele for the second gene.

Hence, a child with brown eyes and red hair will possess genotype: Bbdd since he/she cannot receive two dominant alleles for the first gene from both parents. A child with blue eyes and dark hair will have genotype: bbDd since he/she cannot receive two dominant alleles of the second gene from both parents.

How might a change in pH levels affect enzyme reaction rate and shape in the cell
babunello [35]
Enzymes are highly specific proteins that function best at certain pHs. A change in pH would affect its structure; too high or too low would cause denaturation. When this happens, the enzyme won’t have the correct structure to function as a catalyst. Therefore, reaction rate will slow.

Hope this helps!!
