According to classification, if two organisms are in the same class, then they must be in the same kingdom and A) family B) orde
mario62 [17]

The correct option is C.

if two organisms are in the same class then they will be in the same phylum. The biological classification hierarchy is arranged in such a way that, two organisms who belong to a lower division on the hierarchy will automatically be in the same group in the higher division.

The arrangement from the smallest to largest hierarchy is this: specie, genus, family, order, class, phylum and kingdom.

I need someone to help me plz
Law Incorporation [45]
I'll do my best to help, but do keep in mind that this is just an educated guess on my part. 

Characteristics of Living Viruses:
 - Uses energy (nonliving things can't use energy, for obvious reasons)
 - Exhibits growth and development (for the same reasons as above, nonliving things can't grow)
 - Made up of one or more cells (cells are alive, so nonliving viruses can't be made up of living things)
 - Possesses internal organization (viruses can be complex, as most living things are)
 - Eliminates waste

Characteristics of Nonliving Viruses:
 - Defined boundary (this is a bit vague because a defined boundary isn't suggestive of life or not, so it could really be either or)

Because most of the answers fit with the living characteristics, it makes me think there is something wrong with my answer, but I did some research and that seems pretty accurate. However, I'm not a professional, so I could be wrong. I'm sorry I couldn't help more

Explain the difference between accuracy and
rewona [7]

Accuracy is the closeness of a measurement to the true value whereas precision is the closeness of measurement of similar items.

<h3>Explain the difference between accuracy and precision?</h3>

Accuracy is defined as to how close a measurement or calculation is to the true value while on the other hand, Precision is defined as to how close measurements of the same thing are to each other. Precision is not depend on the accuracy. There is high significance of having data that has both accuracy and precision because these two things provides us information about the rightness of the data.

So we can conclude that accuracy is the closeness of a measurement to the true value whereas precision is the closeness of measurement of similar items.
