Answer:
Increasing the surface area of a solid has no effect on the speed of dissolving. Hence, the correct answer is option B.
Explanation:
The increasing of surface area has no effect on the speed of dissolving at as it is irrelevant with the dissolving speed with the solvent. The dissolving effect air speed can be altered with the temperature and with the volume but is increasing of surface area has no relevance on the dissolving speed.
If the temperature is raised above the room temperature it helps in dissolving speed and dissolving quantity. The increase of surface area can we done by various ways such as expanding through mechanical method, etc.
The cell wall is a rigid organelle composed of cellulose and lying just outside the cell membrane. The cell wall gives the plant cell it's box-like shape. it also protects the cell. The cell wall contains pores which allow materials to pass to and from the cell membrane.

Answer:
<h3><em><u>
It is not made by a geologic process</u></em></h3>
Explanation:
A geologic process is a process which occurs dynamically at earth's surface or land forms. For example, volcanic eruption, weathering, erosion etc.
Whereas minerals are the inorganic substances which are homogeneous and occur naturally with a definite shape.
Sugar comes from plants and therefore it an organic compound. Hence it is not a mineral.
A table sugar undergoes a number of refining processes. It is in crystal form and it is made of more than one element which doesn't relate sugar with minerals.
Thus, we can conclude that <u>table sugar is not a mineral because it is not made by a geologic process.</u>

Hope this help
Have a nice day!!!
