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.

B. Lowering taxes in order to stimulate spending. When the economy experiences a downturn, the government is more likely to cut taxes to allow price competitiveness of goods, thereby triggering demand, hence consumption among households. A boost in consumption should translate into an increase in supply that wwould in turn bring about job creation. The negative trend would therefore be reversed.
Answer:
A. Plant cells have cell walls and chloroplasts, Animal cells do not.
Explanation:
Answer:
2. A change occurs in the environment.
4. Poorly adapted individuals have decreased survivorship.
1. Well-adapted individuals leave more offspring than do poorly adapted individuals.
3. Genetic frequencies within the population change.
Explanation:
The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.
Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.
Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.
Hence, the sequence of events is 2, 4, 1 and 3.
