What kind of channels are located in the input region?
tamaranim1 [39]

Answer:

The correct answer is option B ( ligand gated channels opened by neurotransmitter molecules).

Explanation:

Input region or postsynaptic region or dendrite is the site of neuron cell which receives the impulse from the pre-synaptic neuron at the synaptic junction.

The cell membrane of the dendrite is embedded with ligand-gated channels which opens up in response to the ligand (neurotransmitters) produced by the neurotransmitter vesicle of axon or output region of neuron.

The neuromuscular junction is such a case where acetylcholine receptors present in the dendrite opens in the presence of acetylcholine.

Thus, option B ( ligand-gated channels opened by neurotransmitter molecules) is the correct option.

Inadequate carbohydrate intake results in the breakdown of body protein for use as fuel. true or false
SOVA2 [1]
The statement is true.
Carbohydrates are broken down in order to obtain glucose for respiration in cells. When there is an inadequate amount of carbohydrates, other macromolecules must be broken down. Excessive breakdown of fats is not possible due to the fact that it causes ketosis; therefore, proteins are broken down and the body starts to lose muscle mass.

In humans, syndactyly (webbed digits) is inherited by possession of a dominant allele (S). If a man who is homozygous and normal
____ [38]

Answer:

The % of children with webbed digits is 50%

Explanation:

Given -

Syndactyly or webbed digits are due to the presence of  a dominant allele (S). Then the allele for normal digits would be represented by allele "s"

A normal man with normal digits and genotype "ss" marries a woman with webbed digits and has a hetrozygous genotype i.e "Ss"

If we cross Ss and ss , then the following offspring are produced -

Ss * ss

Ss, Ss, ss, ss

Out of four 2 offspring with genotype ss have normal digits and remaining two offspring with genotype "Ss" have webbed digits. Thus, the % of children with webbed digits is 50%
