What is another natural process that could contribute to the evolution of a species genomes?

Biology
2 answers:
Stells [14]2 years ago
6 0

Answer: A natural disaster, such as an earthquake or a volcanic eruption, could affect the evolution of a species’ genome. These disasters could kill a large number of organisms at once, decreasing the genetic variation in the gene pool. In some cases, large populations may become separated, which can lead to several smaller populations evolving in different ways.

Explanation:

Each base is paired as follows in DNA:

A paired with T

T paired with A

C paired with G

G paired with C

The letters refer to the primary nucleic acid bases: adenine, cytosine, guanine, and thymine.

Complete the following sentence: "When ionic compounds dissociate in water, each ion is surrounded by a sphere of hydration: ___
Archy [21]

Answer:

Cations, Oxygen, Anions, Hydrogen

Explanation:

Water molecule is polar (meaning it has dipoles). The oxygen having a higher atomic mass attracts most of the electron cloud of the molecule becoming partially negatively charged and leaving the hydrogen end to be partially positive.

An Ionic compound is one between two atoms where one donates its electrons to the other for both to achieve stable configuration. The two atoms, therefore, become charged and are bought together by electrostatic forces.

When an ionic compound is put in water, it dissociates into its ions (anions and cations) They attract and repel with the polar water molecules depending on their charges. The anions (negatively charged ion) are surrounded by water molecules with the hydrogen ends and the cations are surrounded by water molecules with the oxygen ends.

The plasma membrane represents an energetic barrier to the free diffusion of ions from the extracellular space into the cytoplas
Marysya12 [62]

Answer:

Why are molecules such as valinomycin effective at transporting ions across the membrane?

Valinomycin is effective as transporting ions across the membrane because it is no charged, so it can carry ions.

Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?

Valinomycin is limited by temperature because its activity is highly sensitive and it depends on a stable and an average temperature.

Explanation:

Valinomycin is effective at transporting ion across the membrane because is an antibiotic that alternates hydroxy and amino acid, ans it helps membranes to be permeable. Valinomycin is a cyclic molecule that helps in ions transportation through membranes. Also, antibiotics have a temperature range of activity, that's why it is sensitive to changes.
