Answer:

Electricity is a secondary energy source that we get from the conversion of other sources of energy such as coal, natural gas, oil, nuclear power, and so on. These sources are known as “primary sources.” Primary sources can be renewable or non-renewable, but the electricity itself is neither.

<h3>What is mutation?</h3>

Mutation is defined as the alteration in the genetic makeup of a living organism which may occur due to the following:

  • When there is spontaneous break down of deoxyribonucleic acid (DNA).
  • Change in a single nucleotide of the DNA.
  • when there is additions or deletions of nucleotide in a DNA strand.

A change can be noticed in an animal such as Chimpanzee when the following occurs:

Mutations in chimpanzee DNA: This can alter both that anatomy and the physiological features of the organism involved.

Crossbreeding between gorillas and chimpanzees: When there is cross breeding between a chimpanzee and a gorilla, it will lead to a genetic diversity which can be observed as a change in the hands of the chimpanzee.

There are no known motor proteins that move on intermediate filaments (IFs).
Harlamova29_29 [7]

Answer: The correct option is E ( Intermediate filaments are unpolarized).

Explanation:

Intermediate Filaments are usually associated with cells that can withstand mechanical stress which includes claws of animals, hair and makes up the dead remnants of the epidermal cell of the skin. Therefore without the supporting network of intermediate filaments, an epithelium remains intact but the cells are prone to damage by abrasive forces.

Intermediate filaments are so named because they are thicker than actin filaments and thinner than microtubules or muscle myosin filaments

The properties or characteristics of an intermediate filaments that explains the lack of motor proteins is as a result of its subunits which are elongated, not globular and are associated in an anti-polar manner. Therefore, the overall filament has no polarity, and therefore no motor proteins move along intermediate filaments

Kryger [21]
I believe the main purpose of wildlife (movement) corridors is to connect two otherwise isolated populations. Wildlife corridors are links of wildlife habitat that joins tow or more larger areas of similar wildlife habitat. They are very critical for the maintenance of ecological processes such as allowing the movement of animals and the continuation of viable populations.
