Correct answer: A). Control

A control variable is something that is kept unchanged in the experiment. It is used as a standard of comparison that is used for checking the results of an experiment.

The control variable is not of primary concern in the experimental outcome. It increases the reliability of the results through a comparison between the control measurements and the other measurements.

Hence, the correct answer would be option A.

Key features that distinguish eukaryotic genomes from prokaryotic genomes include (select all that apply): Group of answer choic
posledela

Answer:

1. Eukaryotic genomes contain large fractions of non-protein coding DNA sequence.

2. Eukaryotic genomes contain "satellite" DNA composed of various types of repetitive elements.

Explanation:

The genome of the eukaryotes and prokaryotes are very different. The eukaryotic genome is much larger as compared to the prokaryotic genome.

The eukaryotic genome is largely due to the presence of some sequence which does not code for any protein called introns and a large amount of sequence which continuously repeats itself in the genome called satellite DNA.

The eukaryotic genome when condenses, it forms an X-shaped called chromosomes whereas the prokaryotic genome is circular and thus is called circular chromosomes.

Thus, the selected option is correct.
