Answer:

C. Active transport

Explanation:

When a molecule moves across a semipermeable membrane into a region of higher concentration it is known as active transport. When there no semipermeable membrane then the movement of molecules from higher concentration to lower concentration is known as diffusion. But when there is a semipermeable membrane in between that time its solvent which moves from higher concentration to the lower concentration not solute and the phenomenon is known as osmosis. This is passive transport and occurs naturally so no energy input is required to be provided for this movement to occur. But, active transport is reverse of passive transport. In active transport, the movement of solvent occurs from lower concentration to higher concentration across a semipermeable membrane. Active transport is not a spontaneous process so in order for active transport to occur we are required to provide an energy input from an outside source.

To efficiently provide the ideal amount of nitrogen fertilizer, some farmers make use of a "chlorophyll meter" that measures the

NikAS [45]

Answer:

Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.

In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.

How would the fossil record look different after the Cambrian Explosion vs. after a mass extinction?

Aliun [14]

The beginning of the Cambrian Period is marked by the evolution of hard body parts such as calcium carbonate shells. ... These body parts fossilize more easily than soft tissues, and thus the fossil record becomes much more complete after their appearance.
