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 <u>spinal cord dorsal horn on the left side</u> and the second being in the <u>thalamus on the right side.</u>
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.

One valid inference that can be made regarding the evolution of modern horses is that : Pliohippus had teeth adapted for grazing
<h3>Description of Pliohippus </h3>
From the information provided in the question The modern day horse resembling the pliohippus can be inferred to have teeth which is adapted for grazing just like the pliohippus.
The pliohippus evolved from the merychippus which is classified as a grazer. because of its longer/taller teeth the pliohippus was more adapted to grazing than been a browser.
Hence we can conclude that One valid inference that can be made regarding the evolution of modern horses is that : Pliohippus had teeth adapted for grazing

It is called ecological succession, which can take up to a decade. It is a process of change in the species structure that occurs after a vast loss or extinction. Ecologists study how complexity is evident when a community is formed or occurrence takes place from an empty land or bare soil.
Most animals are well adapted to their biotic and abiotic conditions due to behavioural, physiological or structural adaptations that increase their chances of survival and reproduction. I looked it up for you
