5. Which describes the variable that is changed to test the prediction?
solong [7]

Answer:

Independent

Explanation:

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

In an experiment , the variable being manipulated by an experimenter is known as an independent variable while the dependent variable is the event expected to change when the independent variable is manipulated.

Hence, independent variable describes the variable that is changed to test the prediction.

How does one species become two different species? 3 sentences.
8090 [49]

Answer:

in explanation

Explanation:

I'd say one species can become two different species by mating. If one species mates with a different species than they carry their genes over to the baby. This would become a repeating cycle making another species.

I don't know if this was the answer you were looking for, but this how animal breeders get a certain type of animal.

The mitochondrial DNA helicase has 612 amino acids. What is the length of the mRNA from this protein is translated ? Show your w
NeTakaya
The answer is 1836 nucleotide bases.

<span>It is known that three nucleotide bases in mRNA are called codon and that each codon codes for the specific amino acid. For 3 nucleotide bases in mRNA, there is 1 amino acid in a protein. So, there are 3 times more nucleotide bases in mRNA than amino acids in the protein. This can be represented mathematically:
3 nucleotide bases : 1 amino acid = x nucleotide bases : 612 amino acids
3 nucleotide bases x 612 amino acids : 1 amino acids = x </span><span>nucleotide bases
x nucleotide bases = 612 x 3 nucleotide bases
x nucleotide bases = 1836 nucleotide bases.
So, mRNA long 1836 nucleotide bases will give a protein with 612 amino acids.</span>
