Answer:

4.769 L

Explanation:

initial volume v_1=4.2\ ltr

We have to find the final volume v_2

initial temperature T_1=0°C=273+0=273 K

final temperature T_2=37°C=273+37=310 k

At constant pressure according to Charles law

\frac{V_2}{V_1}=\frac{T_2}{T_1}

V_2=\frac{T_2}{T_1}\times V_1

V_2=\frac{310}{273}\times 4.2=4.769 L

So the final volume will be 4.769 L

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.
