Answer: A. To break down food into nutrients that can be circulated around the body. :)
Evolution :).
Descent with modification helps to explain anatomical similarities among certain species. The bones of the forelimbs of humans, cats, and bats (you can add in penguins, alligators, and more) are used in different ways but have similar structures.
The best explanation is that these animals have a common ancestor. With new generations, new species emerged by natural selection from different populations, and with this, the bones become better for different tasks.
The forelimbs and other such structures with anatomical similarities due to a common ancestor are called homologous structures.
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.

The dose in milligrams for this patient who is receiving preoperative treatment would be 750 mg, since the dose is 6mg/Kg and he weights 275 pounds (124,73Kgs) multiplied by 6mg and the nurse will administer 15 ml for this dose.
Animals are used for food, products, and services.
