Hurricanes form when warm, moist air rises over the water. Cooler air replaces the rising air. Mr. Gaines's class identified that the pressure in the center of the hurricane is decreasing which indicates the storm is getting stronger as the wind increases, i.e., option 3.
<h3>What is a Hurricane?</h3>
A hurricane is a powerful cyclone that is tropical and forms in the Atlantic or Northeast Pacific Oceans.
Surface atmospheric pressure is fairly low in the center of a hurricane. An eye forms in the center of the storm system as it rotates faster and faster. With very low air pressure, it is very calm and clear in the eye.
Thus, the correct option is 3.

Answer:
Hello!
The answer is A. Analysis of DNA sequences
Explanation:
Classification:
Classification is the assortment or arrangement of living organisms into groups on the basis of their similarities. These groups into which organisms are classified are called taxonomic groups or taxon.
- Before the 1960s, scientists solely relied on phenotypic or physical characteristics of organisms to classify them into related taxonomic groups.
- Modern DNA sequencing methods are capable of revealing similarities and differences between organisms on the level of genes or DNA sequences. Therefore, DNA sequence analysis is the most accurate method for classification.
- Closely related organisms have specific genes with the same DNA sequence. These sequences, known as conserved sequences, can be found universally in all species of a particular organism. For example, in bacteria, a DNA sequence known as the 16s RNA is conserved in related species. 16s RNA analysis is widely used to identify and classify bacteria.
- Behaviors, body structure, habitat and food choices are all phenotypic characters that do not provide definite evidence of evolutionary relationship.
- Different species can have the same habitat, behavior, anatomy and morphology.
Answer:
True.
Explanation:
Genetic drift occurs when a species migrates into another one, therefore making a new variation of the species.
The binomial nomenclature system was used to classify animals, but not until the 1700s when it was first formally introduced by Carl Linnaeus. In ancient times, plants and animals were instead usually just classified in terms of whether or not they were useful, or divided animals into categories such as 'domestic animals, wild animals, creeping animals, flying animals, sea animals'.
