Hemlock woolly adelgid is an insect pest to hemlock trees. It was introduced in the United States during the 1920's. It is not n

ative to the United States and has few natural predators. To control this insect pest, scientists identified a species of predatory beetle, (Pseudoscymnus tsugae). They hope to introduce this beetle to areas where the woolly adelgid is destructive, reduce the woolly adelgid population, and minimize the damage caused to hemlock trees.
Which of these questions BEST summarizes the research described?

A) Are hemlock trees important to the ecosystem?

B) How does the woolly adelgid kill hemlock trees?

C) Can insect pests be used to control damaging predators in sensitive environments?

D) Can predatory beetles help reduce environmental damage caused by the woolly adelgid?

Answer:

Option D, Can predatory beetles help reduce environmental damage caused by the woolly adelgid?

Explanation:

In this paragraph it is described as how a Hemlock woolly adelgid insect/pest is harming the hemlock tree. In order to control this destruction, it was identified by some scientist that Pseudoscymnus tsugae  is a beetle that feeds on this woolly adelgid insect.

Hence, the most appropriate scientific question to ask is "what is the role of predatory beetle  in saving the Hemlock trees?"

Hence, option D is correct.

From the following list, correctly identify the reason(s) that might explain a decrease in Vmax due to a suboptimal pH during an
Zanzabum

Answer:

The correct answer is -

a. Protonation of the substrate.

b. Deprotonation of the amino acids in the enzyme active site.

c. Change in tertiary structure in extreme conditions.

Explanation:

During an enzyme assay, suboptimal pH is changed and affect the Vmax to decrease and this could take place due to various reasons such as-

A) protonation of the substrate - Upon protonating or adding a proton or hydrogen cation to a substrate atom, the mass and the charge of the species each increase by one unit which make a conjugate acid.

B) Deprotonation of the amino acids in the enzyme’s active site -Changing the pH will affect the charges on the amino acid molecules.

C) Denaturation of the protein’s tertiary structure- Tertiary structure of the protein is basically a backbone of peptide chain with one or more secondary domains of proteins that increasing the pH or decreasing the pH get denature.

Thus, the correct answer is : option A, B, C.
