brilliants [131]

Answer:

The correct answer is - option C.

Explanation:

The case in this the biological exterminators asks to use the biological concept which includes spraying the solution of the juvenile hormone to get rid of nymphs of specific insect and according to the assumption, this solution causes some alteration on the ability to reproduce of such nymphs and leads to only nonreproductive ones.

On the given condition the increasing of nymphs, the number of adult nymphs or decreasing of nymphs can not be condition and as the reproductive ability is affected the number of nymphs would be the same.

Thus, the correct answer would be - option C.

Part 1: Why is Fresh Water in Short Supply?
shepuryov [24]

Part 1;

Because there is only limited amounts of fresh water on the Earth the rest is salt water; which humans can not survive on as the salt dehydrates our bodies instead of hydrates.

1) The more we try to get the the fresh water the more we will likely make more pollution.

2) The more we use the less there is.

3) Everything needs water.

Part 2; no idea I believe it is the ice caps, as it is fresh water in the ice caps and not a lot of humans up there to pollute the runoff.

What would be the expected result if a competitive, nonhydrolyzable analog of ATP were applied to the cytoplasmic side of a plas
Yakvenalex [24]

Answer:

The cell interior would experience higher than normal Na+ concentrations and lower than normal K+ concentrations.

Explanation:

The Na/⁺K⁺ pump is an ATPase pump which is responsible for maintaining low Na⁺ and high K⁺ concentrations within the cytoplasm while maintaining high Na⁺ and low K⁺ concentrations in the extracellular fluid.

Since these two ions are moved against their concentration gradient, ATP hydrolysis is required to provide the energy for this process. This is done by moving in two K⁺ ions  inside while moving three Na⁺ ions outside the cell for every molecule of ATP hydrolysed to ADP and Pi.

If a competitive non-hydrolyzable analog of ATP is applied on the cytoplasmic side of a plasma membrane that contained a large concentration of the Na/⁺K⁺ pump, it will act by inhibiting the action of the Na/⁺K⁺ pump. This will result in an accumulation of Na⁺ ions inside the cell and lower than normal K⁺ ions concentration.

Genetically identical armadillos were kept in the same controlled environment from birth and provided the same diet. Even though
Vlada [557]

Phenotypic variations in genetically identical organisms that grow in the same controlled environment may be due to mutation.

<h3>Mutation</h3>

This refers to a sudden change to the DNA sequence of living organisms.

When the DNA base sequence of organisms changes, the effect is shown in the morphology of organisms.

For organisms that are genetically identical but grow in different environments, phenotypic variations might exist as a result of environmentally acquired traits during the struggle to adapt to their environments.

In the same environment, however, genetically identical organisms are not expected to be phenotypically different, unless a mutation to the DNA of one has occurred.
