Independent Variables can be manipulated, and a Dependent Variable are observed and measured. Another way to say it is that the Independent variables change to get different results while the Dependent variables never change because you are trying to see what causes it to change
Answer:
1. A-C-G-G-T is <u>duplication</u>.
2. C-G-T is <u>deletion</u>.
3. A-G-C-T is <u>reordering</u>.
Explanation:
Your original sequence is ACGT. You compare the original sequence to the 3 mutations.
1. There 2 G's now, which means that the G has been duplicated.
2. The A is now gone in the front of the sequence.
3. The C and G were switched.
Answer:
b. It is evolution above the species level.
Explanation:
Macroevolution is the evolution that generates new taxa, for examples two or more species from a common ancestor. Macroevolution is the product of microevolutionary processes, it is, of <u>microevolution</u>: the change in allele frequencies in a population over time. Macroevolutive changes are commonly evident while not all microevlutive changes are not.

Experimentation is a scientific process wherein you test and verify a hypothesis based on its assumption is going to be supported or negated (null hypothesis). Hence experimentation involves the independent and dependent variable, also control variable as a level in the IV. </span>
Answer;
-The most appropriate answer is Lipids
Explanation;
-Lipids is among the four biological biomolecules, the others being proteins, carbohydrates and nucleic acids.
-Lipids are made up of fatty acids and glycerol and are composed of elements carbon, hydrogen, oxygen and they may also contain phosphorus, like in the case of phospholipids which are mainly components of the cell membranes.
-They take two forms, namely; fats and oils. Therefore, the oil form of lipid may be used as lamp oil.
