During a
head injury or a trauma, the brain can limit the spread of the damage by
forming a glial scar which seals off the damaged region from the rest of the
important parts. During this process, the glial cells are particularly
important. In specific, the glial cells Astrocytes will be the most abundant in
this process since they produce glucose and other essential nutrients which help
support the viability of the surviving cells. In addition, the astrocytes is responsible in maintaining the
brain environment stability (homeostasis), supplying nutrition for neurons, and
recycling neurotransmitters.
Therefore the answer to
this question would be:
<span>“Astrocytes”</span>
I'd say that the answer is b.
All batteries are rechargeable, and all glucose. <span />
The answer to 15 is 4 because cellular respiration in the process that produces ATP. Protein synthesis, photosynthesis, and digestion don't directly produce ATP. Carbon dioxide is a by-product of cellular respiration.
Looking at your answer to number 16, I think you might have confused cellular respiration with "regular respiration" or breathing. We breathe in oxygen and breathe out carbon dioxide because the mitochondria in our cells require oxygen to produce ATP, and release carbon dioxide as a byproduct.
Therefore, number 16 isn't cellular respiration. It's not happening within a cell, it's not producing ATP, and mitochondria aren't involved. Instead, it takes place in the lungs (because the alveolus is part of the lungs). You can see that carbon dioxide is being removed from the blood and oxygen is being added. This is the process of gas exchange.

Hope that helps! Feel free to ask if you need clarification or anything :)
D i think again im not sure but thats what i think
