utrients.B. dissolving cell membranes temporarily, permitting cells that were on the verge of dividing divide more rapidly.C. changing the pH within the cell, permitting the electron transport chain to operate more efficiently.D. increasing the activity of proton pumps that lower the pH of cell walls, allowing cells to elongate.

Answer:

The correct answer is D increasing the activity of protons pumps that lowers the pH  of the cell walls allowing cells to elongate.

Explanation:

The plant growth hormone auxin work by increasing the H+ ion concentration thus decreasing the pH of the apoplast.

    The decrease in the pH of the apoplast helps in the cell wall extension that ultimately result in cell growth.

   Auxin hormone exert this effect by increasing the activity of increasing the activity of proton pumps in the apoplastic membrane.

What information can not be obtained from the sequence of a gene?
slavikrds [6]

The question is incomplete as it does not have the options. The options of the given question are:

1. whether the gene is methylated.

2. relationship between two species.

3. effects of mutation on gene function

4. amino acid sequence of the protein

Answer:

The correct answer will be option-1

Explanation:

A gene is the physical segment of the DNA which determines the trait of the organism.

Since gene represents the sequence of DNA which acts as the genetic material of the organism, therefore, studying the DNA  can help determine the effect of the mutation. DNA is a universal molecule therefore studies can help find the relationship between two species. The DNA codes for protein therefore amino acid sequence can be traced.

The methylation of the gene is a post-translational event and controls the expression of gene therefore option-1 is the correct answer.

2. How is the law of conservation of mass observed in a chemical equation?​
Bess [88]

Answer:

This law states that, despite chemical reactions or physical transformations, mass is conserved — that is, it cannot be created or destroyed — within an isolated system. In other words, in a chemical reaction, the mass of the products will always be equal to the mass of the reactants.

hope this helps :)
