Answer:

Some plants absorb all the nutrients in the soil, like the cotton plant, and some return them to the soil, like peanuts. The latter plants are called nitrogen-fixing plants. Rotating these and the former plants (like cotton), replenishes the nutrients in the soil and creates a healthy agricultural cycle.

serg [7]

When Charles Darwin considered wings of birds, apart from his famous proposal he also predicted that fossils will be found with structures that are intermediate between early and modern form.

Answer: Option C

<u>Explanation:</u>

Charles Darwin was basically referring to transitional Fossil while considering Wings of bird. So what are transitional fossil? They are the fossil remains of both the ancestral group and the descendant group.

Since we don’t have enough record of the fossils, it is very difficult to know the accuracy of transitional fossil. However, we do have some record of fossils from which we can gather enough evidence of how the fossils where earlier and how it evolved over a period of time.

The solutions in the two arms of this U-tube are separated by a membrane that is permeable to water and glucose but not to sucro

DaniilM [7]

Answer:

The correct answer to the question is: the level of liquid in Side A will rise.

Explanation:

Sucrose is formed of two molecules of glucose but the membrane is impermeable to it.
The given membrane is said to be permeable to water and glucose.
Through a semi-permeable membrane, molecules tend to move from a region where its concentration is high to another region where its concentration is low by the process of diffusion until its concentration in the two regions becomes equal. This phenomenon is known as Osmosis.
Concentration gradient of a molecule can be defined as the difference in the concentration of the molecule in two different regions separated by a semi-permeable membrane.
Considering glucose, the concentration of glucose is low in side A (1M) and high in side B (2M), so it will tend to move from side B to side A down its concentration gradient.
Considering sucrose, although its concentration is high in side A (2M) but low in side B (1M), it is unable to move as the membrane is impermeable to it.
Water tend to move from a region where the concentration of solute is low (or water concentration is high) to a region where the concentration of solute is high (or water concentration is low).
Due to the movement of glucose from side B to side A, the concentration of total solute concentration becomes high in side A as compared to side B. Therefore, water would move from side B to side A.
Hence the level of liquid in Side A will rise after sometime.
