Brain cells that are neither neurons nor glia, but which are capable of dividing and then differentiating into neurons or glia,
solong [7]

ANSWER:

Brain cells that are neither neurons nor glia, but which are capable of dividing and then differentiating into neurons or glia, are called NEURAL STEM CELLS.

EXPLANATION:

Neural stem cells are undifferentiated cells originating in the central nervous system.

Neural stem cells (NSCs) have the potential to give rise to the radial glial progenitor cells that grow and differentiate into neurons and glial cells.

NSCs have an important role during development producing the enormous diversity of neurons, astrocytes and oligodendrocytes in the developing CNS.

A NEURON (nerve cell) is a specialized cell that conveys electrochemical impulses throughout the body.

provide support for and insulation between them.

GLIAL CELLS are the most abundant cell types in the central nervous system. Types of glial cells include oligodendrocytes, astrocytes, ependymal cells, Schwann cells, microglia, and satellite cells.

What role does H20 have in cellular respiration
Marizza181 [45]

Answer:

H_{2}O or Water is a very important component of the cellular respiration. However, it does not act in the process of cellular respiration directly, but is produced at the end of the cellular respiration during Oxidative Phosphorylation or Electron Transport System.

Basically, what happens is during the stages ETS, the NADH and FADH_{2} gets converted into NAD and FAD whereas the H^{+} ion accumulates into the inter-membrane space, which then passes through the ATP synthase molecule from the inter-membrane space to the matrix thus, stimulating the ATP synthase molecule to produce ATP the most important product of cellular respiration. This H^{+} ion when enters the matrix gets utilized to form H_{2}O by getting bound to O_{2}. But if no H_{2}O is produced in the final stage and the H^{+} ion gets accumulated in the matrix then the cellular machinery will malfunction and the production of ATP will stop. Thus, by this fact, we know that H_{2}O has a very important role in cellular respiration.

How long does it take a newborn calf to start running and why?
Tanya [424]
<span>A newborn calf can (typically) walk and run on its own within a time period ranging to 10 minutes, to a couple hours after birth, and at most, 24 hours afterwards. Reason for this being that a healthy calf will have gotten enough colostrum from their mother to be able to fair well on their own. </span>
