Answer:
The gray matter in the spinal cord is located in the <u><em>grey column</em></u> , and its shape resembles a letter H, or a butterfly. The cell bodies of somatic motor neurons are primarily housed in the <u><em>ventral or anterior</em></u> horns, which innervate skeletal muscle.
Explanation:
The grey matter is a component of the central nervous system that contains neuronal and glial cells and it can be found in the brain, brainstem and <em>spinal cord, in this last one, is found in the grey column, a mass of grey matter shaped in H form.</em>
In this column the grey matter is divided into four columns (as you can see in the image I added):
- The dorsal or posterior horn: contains somatosensorial neurons
- <em> The ventral or anterior horn: contains somatic efferent motor neurons (they exit the spinal cord to innervate skeletal muscle) </em>
- The intermediate column: contains neurons to innervate visceral organs
- The lateral horn: same as the intermediate column
I hope you find this information useful and interesting! Good luck!

Answer: Brainstem
Explanation:
The brain stem controls the flow of messages between the brain and rest of the body. There is no requirement of conscious mind for the basic functions of the body.
These functions are breathing, swallowing, heat rate, blood pressure. It takes place even when the person is sleepy, there is need to be awake.
These are the basic functions of the body which is required for the survival of organism.
Answer: option D) Cells can function equally as well at all pH's because enzymes are effective at all pH's.
Explanation:
Studies in biology have demonstrated that:
- All living tissues have different pH (stomach is acidic, it has a pH below 7; saliva is alkaline, it has pH above 7 etc)
- All living tissues has a stable physiological temperature of 37°c
- All living tissues contain enzymes such as Catalase
Thus, based on the information given, we can infer that all cells can function equally as well at all pH's (whether acidic, neutral or alkaline) because enzymes are also effective at all pH's.
The answer is D. Meadow animals that eat plants and plant products.
This is because the rabbits are primary consumers, which means they eat autotrophs. Other animals that eat plants like rabbits do would be on the same trophic level as them.
