Answer:
Independent: Purposely altered
Dependent: Changes with respect to the independent being altered
Controlled: Never changes
Explanation:
An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.
A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.
A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.
Answer:
The correct answer is 4. The presence of a polar or charged head group attached to the phosphate.
Explanation:
Lipids have a hydrophilic head and a hydrophobic tail. This allows them to form structures where the tails are hidden on the inside, and the heads interact with the water molecules. This conformation is the best energetically and allows the lipids to interact with aqueous environments.
Protons: positive
neutrons: no charge
electrons: negative
