Mandarinka [93]3 years ago
6 0

Answer:

The correct answer is B)10%. See the explanation below, please.

Explanation:

We use the following equivalence, remembering that Adenina pairs with Timina and Guanina with Cytosine:

A=T   ; C=G   A+G=T+C

If A= 40% ----> T=40%

A+G=T+C

40%+G= 40% +C   ---->  40+10=50

G=C=10%

Scientists use a standardized taxonomic system to separate organisms into hierarchical groups based on
den301095 [7]

It allows different kinds of organisms to be easily identified based on their characteristics

Explanation:

Classification is defined as the grouping of organisms based on their similarities and dissimilarities. The main aim of classification is to simplify the study of vast range of animals that exist in nature.

The scientists use a standardized method in which they follow a set of rules while studying and assigning a taxonomic rank to a newly studied organism.

The taxonomic hierarchy includes the following taxon-Kingdom, phylum,class, order, family, genus, species.

Beginning from Kingdom the percentage of similarities among the members keep on increasing while we move towards  species.

A taxonomical rank is assigned to an organism by studying the similarities of that organism with already existing members of that taxonomic group.

Since, few characters are already studied well while classifying the earlier members the study and classification of new organism becomes much simplified and easier.
