Answer:
chemical nature of the membrane
Explanation:
The cell membrane is bilayer of amphipathic phospholipids and proteins The hydrophobic tails of phospholipids make the inner core of the membrane while hydrophilic heads are oriented towards the surface of the membrane.
The membrane is selectively permeable as it allows only nonpolar, small and uncharged substances to pass through its hydrophobic inner core. Hence, the chemical nature of the membrane makes it choose the allowed substances to be transported.

Answer and explanation;
The steps followed in an experiment include;
-Observation; this involves
taking note of something such as a curious phenomenon worth further thought and investigation
-Research; it involves forming a question so as to find out more about the natural phenomenon observed.
-Hypothesis, this is an informed guess as to the possible answer of the question.Its purpose is not to arrive at the perfect answer to the question but to provide a direction to further scientific investigation.
-Experiment, the hypothesis formed must be tested by conducting a well designed and controlled experiment. Its is an important step as it proves whether the hypothesis is correct or wrong.
-Analysis; it entails taking down the results and analyzing it together with the data and suing it to draw conclusion regarding the strength of the hypothesis.
-Conclusion; From the analysis a conclusion about the hypothesis can be drawn, explaining why the phenomenon occurs.
-Publish; the results may then be published as a reference and for future use and comparison.
The steps followed in an experiment are as follows: Observation, Research, Hypothesis, Experiment, Analysis, Conclusion, and Publication.
1. Observation: This involves noticing and identifying a curious phenomenon or event that requires further investigation.
2. Research: Conduct background research to gather existing knowledge and information related to the observed phenomenon. Formulate a question or hypothesis based on this research.
3. Hypothesis: Develop an informed guess or prediction about the possible answer to the research question. The hypothesis provides a direction for the experiment and serves as a tentative explanation for the observed phenomenon.
4. Experiment: Design and conduct a well-controlled experiment to test the hypothesis. Plan the procedures, identify variables, establish control groups, and collect data through systematic observations and measurements.
5. Analysis: Analyze the collected data using statistical or analytical methods. Look for patterns, trends, and relationships in the data to determine whether the hypothesis is supported or refuted.
6. Conclusion: Based on the analysis of the data, draw conclusions about the hypothesis. Explain the findings and discuss their implications in relation to the original research question. Assess the strength of the hypothesis and its alignment with the observed data.
7. Publication: Share the results of the experiment by publishing them in a scientific journal or presenting them at conferences. This allows other researchers to review, replicate, and build upon the findings, contributing to the scientific knowledge and understanding of the phenomenon.

Answer:
A geneticist is a science who studies genes, including how they are inherited, mutated, activated, or inactivated. They often study the role that genes play in disease and health.
Explanation:
Geneticists must be able to conduct scientific experiments and analyses with accuracy and precision.
