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!

A unicellular organism that produces glucose through photosynthesis would most likely contain which structure
kap26 [50]
<span>Bacteria are tiny. A typical bacterial cell is just a few micrometres across (a few thousandths of a millimetre). The structure of a bacterial cell is different to an animal or plant cell. For example, they do not have a nucleus but they may have a flagellum. This is a tail-like part of the cell that can spin, moving the cell along.A unicellular organism is a living thing that is just one cell. There are different types of unicellular organism, including: bacteria protozoa unicellular fungi You might be tempted to think that these organisms are very simple, but in fact they can be very complex. They have adaptations that make them very well suited for life in their environment.Protozoa are unicellular organisms that live in water or in damp places. The amoeba is an example of one. Although it is just one cell, it has adaptations that let it behave a bit like an animal: it produces pseudopodia (false feet) that let it move about its pseudopodia can surround food and take it inside the cell contractile vacuoles appear inside the cell, then merge with the surface to remove waste

You may be familiar with fungi from seeing mushrooms and toadstools. Yeast are unicellular fungi. They are used by brewers and wine-makers because they convert sugar into alcohol, and by bakers because they can produce carbon dioxide to make bread to rise. Yeast have a cell wall, like plant cells, but no chloroplasts. This means they have to absorb sugars for their nutrition, rather than being able to make their own food by photosynthesis Yeast can reproduce by producing a bud. The bud grows until it is large enough to split from the parent cell as a new yeast cell.</span>

What might happen if you make a hole using a pointed object to any of the two small<br> balloons?
luda_lava [24]

Answer:If the balloons are filled with air all of the air will try and escape from the balloon out of the hole but if the balloon is filled very tightly with air it will burst because there is too much pressure trying to escape such a small hole so it goes PoP!

Explanation:

Not researched this answer was from common knowledge so if you have a correction or better answer please inform me I will be happy to learn more.

Which factor is least likely to affect the results and interpretation of a functional MRI?
sergij07 [2.7K]
Prescription medication is the least likely to affect the results and interpretation of a functional MRI.

Here are some of the factors that is most likely to affect the results of MRI :

- Caffeinated soda. Caffeinated soda tend to constrict the blood vessels in the brain, which will affect MRI results.
- cancerous growth, will create a huge shadow on MRI results
- sprained ankle, especially if it was fixed with metal bandage, will cause harm during MRI
