They use DNA sequencing to identify species via genetic differences.
<h3>What is the significance of DNA sequencing?</h3>
The four chemical "bases" that make up the DNA molecule must be identified in the correct order in order to sequence DNA. The sequence provides information to scientists about the type of genetic data that is contained in a certain DNA segment.
For instance, scientists can utilize sequence data to identify the DNA segments that contain genes and the segments that carry regulatory instructions that switch genes on and off. Furthermore, and this is crucial, sequencing data might point out variations in a gene that might be harmful.
Large DNA lengths, 1 million bases or more, from various individuals can now be compared swiftly and affordably by researchers. Such comparisons can reveal a wealth of information regarding how inheritance affects illness susceptibility and how the body reacts to environmental factors. The potential for diagnostics and treatments is also greatly increased by the faster and more affordable genome sequencing.
The biology of development and evolution can also be better understood by comparing the genomic sequences of other animals and species, like yeast and chimpanzees.

DDT (Dichloro-diphenyl Trichloroethane) is a biocide. Biocides is the term that is broadly used to refer bactericides, fungicides, nematicides, insecticides, rodenticides and weedicides. A long term use of DDT can have favourable effect by resulting in complete eradication of the potential pests and invaders from an agricultural field. But the use of DDT for a long time has showed dangerous outcomes in the form of Biomagnification that resulted in tremendous decrease in bird population.
Explanation:
Biomagnification is defined as a gradual increase in concentration of a substance in successive trophic levels of a food chain.
Biomagnification of DDT interfered with the egg-shell formation and the thin shelled eggs broke at a premature stage. Thus , the bird population decreased significantly.
I would go with B. Because they are the most used.
Answer:
Linkage
Explanation:
Two genes that occur on the same chromosome are said to be linked, and those that occur very close together are tightly linked.
Answer:
Dogs smell a lot better than humans, because they have more complex nose structures that allow them to follow any scent
