Consequently, the interactions between water and the other constituents of cells are of central importance in biological chemistry.
It would be the nuclear membrane

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.
