I believe the correct answer would be <span>variation. The definition of variation in biology means,</span><span> any difference
between cells, individual organisms, or groups of organisms of any
species caused either by genetic differences or by the effect of environmental factors on the expression of the genetic potentials. So i think that organisms can also be classified as variation. Hope this helped. ♥ ☺

The correct answer is (d.) proteins. Higher organisms use nitrogen to make their protein. Food that is containing protein also involves nitrogen in it. Protein also has amino acids that contain nitrogen in it which is a necessary essential nutrient for the body.
The retinas of night hunting animals have more rod cells which enable them to see better with minimum light.
Answer:
each new cell needs a DNA copy, which serves as instructions on how to function as a cell. DNA replicates before a cell divides. The replication process is semi-conservative, which means that when DNA creates a copy, half of the old strand is retained in the new strand to reduce the number of copy errors.
Explanation:
The answer to this question is A. Eukaryotic
Eukaryotic cells are distinguished by membrane-bounded organelles that contain genetic information and protected by nuclear protein.
In this place, DNA is combined together by proteins and placed accrodingly into the chromosomes.
