Microvilli are the structures of fingerlike projections that greatly increase the absorbing surface of the cells.

<h3>What is Microvilli? </h3>

Microvilli are membrane protrusions that resemble fingers and are sustained by the actin cytoskeleton. They are present in practically all cell types. An increasing amount of research indicates that the highly curved membranes of the dynamic lymphocyte microvilli play a critical role in signal transduction that triggers immunological responses.

The examination of the process that generates curvature and its functional implications in signaling, however, was impeded by difficulties in altering local membrane curvature and tracking the high dynamicity of microvilli. Recent developments in adaptive super-resolution microscopy have helped to partially overcome these technological obstacles.

Therefore the structure that increases the absorbing surface area is called microvilli.

Can you identify the process by which natural selection acts on an insect population exposed to pesticides?

NeTakaya

Identify the process by which natural selection acts on Change in Population the surviving insects reproduce. The frequency of resistant insects in the population increases.

Pesticides are any poisonous substances that are employed to kill animals, fungi, or plants and cause financial loss to crops or ornamental plants or pose a risk to domestic animals' or humans' health.
A pesticide is used on an insect population. Some insects possess a trait that renders them pesticide resistant. These flies remain. Without the gene, insects perish.

Insects that are still alive reproduce. Insects that are resistant are becoming more prevalent. Ecological Change Insecticide is used on a population of them.
Choosing Pressure Some insects have a trait that renders them pesticide resistant. These bugs are persistent. Without the gene, insects perish.

This is referred to as: spontaneous recovery

Spontaneous recovery is a theory of learning and memory which involves unexpected and recurrence of a conditioned response after a period of reduced response or delay. Spontaneous recovery is associated with classical conditioning and operant conditioning. Extinction will happen quickly after a spontaneous recovery, if the conditioned and unconditioned stimulus is not connected.

Which statements describe telomeres and the actions of telomerase?

docker41 [41]

Answer:

Option (d).

Explanation:

Telomere may be defined as the repetitive DNA sequence present at the ends of the chromosomes. Telomeres consists of the nucleotide sequence rich in G and consists of vertebrate sequence AGGGTT.

The mutation in telomerase enzyme can cause the excessive replication of the telomeres. These leads to the excessive cellular proliferation and makes the cell immortal. This extensive growth of telomere is one of the maine reason of the cancer development.

Thus, the correct answer is option (d).
