Question 2

you can increase the surface area of a block of ice by

a)melting it

b)putting it in the freezer

c)crushing it

d)adding salt to it

You can increase the surface area of a block of ice by melting it. Therefore, the correct answer to the above question is option A.  

Explanation:

A block of ice is made from the water which is freeze at zero degree centigrade. The ice has more yeah that's why its volume is more than water. The presence of air is the only reason that the ice floats on the water.

The melting procedure can increase the surface area by decreasing the volume. The melting can be done by various procedure by applying heat air keeping the block of ice in the room temperature. Hence, we can see that melting can increase the surface area of the block of ice.

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.
