Answer:
Low - The generation of nitrates (NO 3-) requires oxygen, so the oxygen levels will be low
Explanation:
Nitrates are formed when the ammonia react with oxygen present in water. The oxygen which react with ammonia is not the oxygen of water molecule, it is the dissolved oxygen. This oxygen is used by aquatic animals for breathing. If nitrates are formed so the concentration of dissolved oxygen will be lowered which causes suffocation and bad impact on marine organisms and the whole ecosystem will be disturbed.
Drosophilia, is the genus name.
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.
Question: Many molecules are moved through the body by?
Answer:<u> The molecules are moved through the body by uses special transport proteins to move molecules across the membrane that cannot pass thorough on their own. Usually large molecules. Carrier proteins blind and carry the molecules across the cell membrane. They provide an open channel of passageway through the cell membrane for molecules to move across.</u>
