The correct answers are A. The cell membrane is very selective, D. The cell membrane is a protective layer surrounding a cell, and E. The cell membrane allows waste to leave the cell.

Explanation:

The cell membrane is a membrane composed of lipids and proteins that surround and define every cell. This membrane had an important role because it regulates the substances and particles that enter and exit from the cell. The cell membrane is very selective as just certain substance can go out an in; for example, the cell membrane allows oxygen to enter into the cell and waste to leave the cell as this preserves the balance in the cell and it is necessary. Moreover, the cell membrane protects the cell from outside isolating it and avoiding nocive particles enter. According to this, it is true this structure is very selective, it acts as a protective layer and also it allows waste to leave the cell.

Why do you think the snapper population changed the way it did?
maksim [4K]

sammy [17]

Answer:

The correct answer is D. is a facultative anaerobe

Explanation:

A facultative anaerobe is the organisms that can live in the absence of oxygen but prefer to utilize the oxygen when oxygen is present in the environment.  

An anaerobic organism requires more amount of energy sources like carbohydrates because they use the fermentation process to make energy and this process results in the formation of less energy than aerobic respiration.  

All the bacteria of family Enterobacteriaceae that live in the intestine are facultative anaerobes. Therefore facultative anaerobe can thrive in both the presence and absence of oxygen so the correct answer is D. is a facultative anaerobe.

Sloan [31]

CAM plants keep stomata closed in the daytime, thus reducing loss of water. They can do this because they - fix CO{2} into organic acids during the night.

The correct option is a.

As an adaptation to dry environments, certain plants developed a carbon fixation mechanism known as crassulacean acid metabolism, or CAM photosynthesis, which enables a plant to photosynthesize during the day but only exchange gases at night.

During the day, the malate is transferred to chloroplasts where it is transformed back to CO2, which is then utilised during photosynthesis. At night, the CO2 is stored as the four-carbon acid malic acid in vacuoles. The enzyme RuBisCO is surrounded by a concentration of pre-collected CO2, which improves photosynthetic efficiency. Plants in the Crassulaceae family were the ones that initially revealed this process of acid metabolism.
