The crossing over mechanism of genetic variation results from the exchange of gene segments between non sister chromatids. The correct answer is A.
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.

Parenteral route
injecting a drug into the body, includes intradermal, SQ, IM, IV routes. Drugs given IV route produce the most rapid actions because they are given directly into the bloodstream.
Answer with Explanation:
"Biome" refers to the flora (plant life) and fauna (animal life) of a particular place. It also includes the climate and specific conditions that allow the living organisms in the environment to survive.
The biome of North Africa consists of both desert biome and rainforest biome. It can be classified into a "savannah biome." This means that both the grassland and the woodland co-exist with each other. On the contrary, the biome in Iceland consists of a "tundra biome." The appearance of this biome is uniform and it is considered the coldest among all the other biomes.
Both of the biomes in North Africa and Iceland are different owing to their temperature, precipitation, nutrients from the soil and so on. The savannah biome consists of both wet and dry climates. These seasons allow the growth of both trees and grasslands. When it comes to the tundra biome, its temperature is extremely low. Thus, it doesn't allow many plants or trees to grow. However, it allows the growth of some unique types of wildlife such as the "Arctic fox."
