We see rainbows when the son is behind us and some type of water or rain is in front of us. When the sun light hits a raindrop it's refracted and is changed in direction.
(and we see them with our eyes mannnn or womannnn)
First of all, let's think about the scientific method, and its processes of how it works.
It all starts with observation, so we need to check all the data we have and all the information that can be collected to have a good thought on what's going on.
After gathering enough information, let's think about a hypothesis that could help solving this problem. Well, reading the question, we can check that that region passed through the wettest summer in 100 years, and that's the main problem here, because before this weather, was this disease a problem? I guess not, so this can be a reason, the change in the percentage of water in the air.
With that said, we need to test if this is true or not, and for that, we'll need mosquitoes with the West Nile virus, and we'll put them in different environments, one that it's wet, and another one that it's not that wet, just like the West Nile problem. This way we can check if this is the problem or not, if it's affecting their reproduction and etc.
Water cycle because water or a chemical element is continuously recycled in an ecosystem which is biogeochemical
The rocks would be younger the closer you get to the ridge
The Mid-Atlantic ridge is a divergent tectonic boundary in the middle of Atlantic Ocean spanning north to south.
Explanation:
At a divergent boundary, a phenomenon called seafloor spreading occurs as new crust is formed along the ridge. New crust seems to 'spread' from the ridge. Therefore, the farther away from the ridge you get, the older the crust gets. This occurs because magma from the mantle rises to replace the void created by the tectonic plates moving away. The magma rises and cools creating a mountainous ridge long the boundary. Seafloor spreading, however, happens really slowly and the changes are only perceptible over 1000s and millions of years.

Answer:
The correct answer is paired sample t-test.
Explanation:
Based on the given information, the mothers living in poverty in the United States give birth to underweight babies. The average weight of the babies given birth by women living in poverty is 2.8 kg. To examine the efficacy of a novel prenatal care program, a test was conducted by the CDC in which 30 mothers living in poverty and the weights of their babies were recorded.
As the test is conducted in pairs, thus, paired sample t-test would be the appropriate hypothesis test. The paired t-test is performed when the dependent variable is measure spontaneously. In the given case, the women participating in the program and the number of babies with less birth weight are examined in pairs. Thus, as the sample are paired together, the correct answer would be paired sample t-test.
