Water molecules diffuse through the cell membrane through aquaporins. How are these proteins helpful in osmosis?
romanna [79]

Answer:

Aquaporins acts as water channels that conduct water to and fro cell membrane during osmosis

Explanation:

Osmosis is a type of cellular transport in which water moves from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane. The osmotic process occurs with the aid of selective protein channels called AQUAPORINS. They allow only the passage of water and prevent that of ions and solutes.

Aquaporins help in the osmotic process by creating a channel for the passage of water molecules across the membrane. In other words, aquaporins facilitate the speedy movement of water molecules across membranes via osmosis, which is normally slow due to the POLARITY OF WATER MOLECULES.

finlep [7]

Answer:

The correct answer is - loss of soil moisture east of mountain ranges.

1. Discuss at least two attributes of a study that you would look for to determine whether or not it is rigorous.
noname [10]

Some of the aspects that help you determine whether a study is rigorous are questions and hypotheses that can be answered, adequated method use, and bibliography.

Rigorous is a term that refers to a quality that focuses on accuracy and precision to comply with norms, precepts, and pre-established rules. This term is widely used in science to refer to the precision of a study or investigation.

Therefore, when it is established that a study is rigorous, its attributes must be taken into account, such as:

- Questions and hypotheses that can be answered: This aspect refers to the investigator having the ability to limit his study so that it is appropriate to do so and does not include too much information that makes his study "impossible".

- Adequated methods use: This refers to using the appropriate methods to reach feasible conclusions, for example, methods of observation, deduction, induction, among others.

- Bibliography: This refers to the research or study being supported by reliable sources so that it is as accurate as the information it provides.
