Answer: 1. Phosphatidyl serine: the phosphoserine group

2.Sphingomyelin: the phosphocholine group

3.Cholesterol: the hydroxyl group

4. Triacylglycerol: the ester bond between glycerol and fatty acids.

Explanation:

Amphipathic molecules have parts that are hydrophobic and hydrophilic. The cell membrane is made up of amphipathic molecules.

Phosphatidyl serine has a polar (hydrophilic) head named the phosphoserine group, the fatty acid group forms the chain.

Sphingomyelin consist of phosphicholine and ceramide. The phosphocholine group is the hydrophilic part while the ceramide is the hydrophobic part.

Cholesterol contains a hydroxyl group (-OH) that is polar while the rest part of the cholesterol is non polar.

Triacylglycerol is made up of glycerol and 3 fatty acid chains. The ester bonds between glycerol and the fatty acids is the Polar part of triacylglycerol.

Hypothesis: If the porosity of three soils are tested, then red clay soil will have the lowest porosity.
NNADVOKAT [17]

Answer:

This question is incomplete, based on the given hypothesis, the question is asking to identify the variables (independent and dependent) of the experiment.

*Independent variable: DIFFERENT SOILS

*Dependent variable: Porosity

Explanation:

- Independent variable is the variable that is manipulated or changed by an experimenter in order to effect a response in another variable. In this question, three different soils were used, hence, the SOIL is the independent variable.

- Dependent variable is the variable that responds to changes made to the independent variable. It is the variable being measured in an experiment. In this case, the porosity is the variable being measured, hence, it is the dependent variable.
