Answer:

The correct answer will be option-B

Explanation:

Meissner corpuscles are one of four types of mechanoreceptors which response to mechanical pressure.

The corpuscles are very adaptive and sensitive receptors which convert the stimuli to action potential and send them to the Central nervous system.

The corpuscles are found in the areas which are exposed to touch or are sensitive to touch like in the fingers of the hand and the lips.

Since the deaf and blind lady distinguishes people with a light touch, therefore, these Meissner corpuscles are involved in helping identify the individuals.

Thus, Option-B is the correct answer.

How does the number of hydrogen atoms compare to the number of oxygen atoms in ribose
zalisa [80]

Answer: Ribose C5H10O5

Explanation:

Ribose is a carbohydrates with the formula C5H10O5. This molecule is pentose monosaccharide which has linear form of  H−(C=O)−(CHOH)4−H. The hyoxyl groups lie in the same side in the form of Fischer Projections.

The number of hydrogen atoms are double in number of the oxygen atoms. The ribose sugar is found in the RNA.

It is the genetic material which is found in some of the organism that carries information from one generation to another.

A mutation is found in a tRNA-encoding gene. The wild type allele produces a tRNA that recognizes the codon GAA, and is charged
Kobotan [32]

Answer:

It will bring about a stop to the translation process

Explanation:

The mutant tRNA despite still being charged with Glu, since it's anticodon is mutated and then recognizes and reads the codon UAA which is one of the  stop codons (UAA, UAG and UGA) on the mRNA strand causes the translation process of that particular mRNA strand to stop. And the growing polypeptide chain to be released if any from the ribosomes.

Skin nerve impulses initiated in mechanoreceptors are transmitted along which type of fiber?
Anettt [7]

Skin nerve impulses initiated in mechanoreceptors are transmitted along type B fiber

<h3>What are mechanoreceptors ?</h3>

These detect mechanical deformation e.g. touch or pressure within the skin; stretch receptors in muscles. * mechanoreceptor cells answer a change in the external stimulus (pressure, temperature, etc) by producing voltage pulses across neurons (i.e. generator potentials)

<h3>Where are mechanoreceptors found?</h3>

Mechanoreceptors are sensory neurons or peripheral afferents located within joint capsular tissues, ligaments, tendons, muscle, and skin. Four primary sorts of afferent mechanoreceptors are commonly present in noncontractile capsular and ligamentous structures in human joints: types I, II, III, and IV

<h2>What sends impulses from the skin?</h2>

First-order neurons receive impulses from skin and proprioceptors and send them to the medulla spinalis . They then synapse with second-order neurons. Second-order neurons sleep in the dorsal horn and send impulses to the thalamus and cerebellum
