The neural pathway bringing temperature information from your left hand to the somatosensory cortex would have two synapses, wit

Westkost [7]

Answer:

The neural pathway bringing temperature information from your left hand to the somatosensory cortex would have two synapses, with the first being in the spinal cord dorsal horn on the left side and the second being in the thalamus on the right side.

Explanation:

The stimuli received by the external receptors must travel from the place where they are produced to the association centers located in the central nervous system, where the information is processed.

In the case of the sensory nerves, which conduct the temperature-related information from the left hand, it happens that:

They make their first synapse in the posterior horn of the spinal cord, responsible for receiving nerve impulses of sensitivity, on the same side as the stimulus (left).
The second synapse occurs in the thalamus, an organ of the central nervous system that is responsible for receiving information related to temperature. As the sensory and motor pathways are crossed, the portion of the thalamus that receives the information is the right one.

One of the consequences of the crossing of the sensory pathways is that everything related to one side of the body is processed on the opposite side of the somatosensory cortex.

If the ancestral form for a particular lineage was aquatic and used gills for respiration, what changes would you expect to see

Marat540 [252]

<h2>The Respiration of Gills</h2>

Explanation:

A dominant part of aquatic animals like fish and prawns inhale through uncommon organs called gills.
The skin that help in utilizing oxygen broke up in water. which help in return of gases and Gills contain veins.
Amphibian life forms have a unique organ called gills, which permits them to inhale oxygen in the water.
The two sides of the pharynx (throat) by the Gills when the gases exchange in fish .
Gills are tissues that resemble short strings, protein structures called fibers.
These fibers have numerous capacities including the exchange of particles and water, just as the trading of oxygen, carbon dioxide, acids and alkali.

Hemoglobin is a protein in the blood that is made of 4 polypeptide chains. Two alpha chains are composed of 141 amino acids each

Ghella [55]

Amino acid differs at the glutamine, which is converted to valine in hemoglobin S. the body produced hemoglobin S due to a point mutation in the DNA sequence which results in different amino acid to be formed during translation of DNA sequence codons.
