Answer:
When water is added to a graduated cylinder, having a surface where the sides of the water look higher than the center means that the curved surface is a concave meniscus which has formed because of surface tension (Choice C).
Explanation:
A meniscus is simply the curvature that the surface of a liquid acquires when it is in a container, such as a graduated cylinder. It is concave when there is attraction between molecules -water and glass- or it can be convex when both surfaces are repelled.
<u>Water is a polar molecule</u>, with the capacity to adhere to the surfaces it comes into contact with. This characteristic causes it to form a concave meniscus, as the outermost molecules adhere to the glass surface, while the surface tension of the water attracts the molecules from the centre downwards, causing the concavity.

The plant cells communicate across cell walls through Plasmodesmata.
how do plant cells communicate across cell walls?
- Between tiny channels woven through the walls of neighboring plant cells, plant cells can communicate with one another through channels referred to as plasmodesmata.
- These channels enable chemicals to move freely between cells, allowing plants to grow regularly and form tissues and organs.
- However, plasmodesmata also act as entryways that viruses can employ to infect an increasing number of cells.
- Given these advantages and disadvantages, plants must balance the permeability of their plasmodesmata in order to move materials from one cell to another while preventing the spread of infection.

Answer: C. Dead snake fossilizing underground.
A fossil fuel is the fuel that is formed by natural processes, such as anaerobic decomposition of dead plants and animals underground. These organisms and their remains remain deep inside the depth of numerous layers of soil resulting in fuel produced after millions of years. A carbon sink refers to a natural or artificial reservoir that stores and absorbs atmospheric carbon by physical and biological process. The formation of fossil fuel inside the earth is carbon sink.
Dead snake will be added as a matter on which biological activity called as decomposition will take place. The organic matter of dead snake will be decomposed by microbes in the soil. The organic matter being the source of carbon, after decomposition will become the reservoir of carbon in the form of fossil fuel.
Therefore, dead snake fossilizing underground is the example of carbon source becoming a carbon sink.
