Answer:

Explanation:

When a flask is dipped in very hot water in a large beaker , the flask expands due to heat gain . As a result , level of water in tube fitted in flask goes down .

After some time , the water inside tube also become hot so it expands  . coefficient of volume expansion of water is more than coefficient of volume expansion of glass . Hence greater expansion takes place in the volume of water . It is due to this fact that water level in tube starts rising after some time of fall .

Explain what is cellular growth and repair? Why is it important?
HACTEHA [7]

Answer:

Cell growth usually refers to cell proliferation, the increase in cell numbers that occurs through repeated cell division. Cell growth can also refer to the enlargement of cell volume, which can take place in the absence of cell division. As living things grow, some cells die or become damaged and need replacements. Some single-celled organisms use a type of mitosis as their only form of reproduction. In multicellular organisms, cell division allows individuals to grow and change by expanding the number of total cells.

Hope this helps!!!

Determine the direction of bond polarity for each compound. Leave it blank for a nonpolar bond. Br−Br H−Cl F−CH3
NeX [460]

Answer:

For H-Cl, the direction is towards the chlorine atom

For F-CH3, the direction is towards the flourine atom.

Explanation:

The dipole moment is a vector quantity. This implies that it has both magnitude and direction.

Thus, the direction of the dipole moment always points from the positive atom towards the negative atom.

This explains the fact that it points to chlorine in HCl and points to flourine in F-CH3
