If a population of 1,000 individuals has 160 rr genotypes, assuming simple dominance by the A allele, what is the frequency of t
Ratling [72]

Answer:

<h2><em>To find the answer, I must 160/1,000 = .16, so .16 = q2 and q = .4. Since p + .4 (q) = 1, p (The dominant allele) = .6, which is the correct answer. A strategy I could use in the future to make the question less challenging is double checking the problem and how it is worded so I don’t make that mistake again.</em></h2>

How can scientists use the two types of waves (P waves and S waves) that earthquakes generate to develop an
azamat

Answer:

The correct answer is as showed in the Explanation

Explanation:

Seismic waves are waves of energy that are produced due to Earth's layers movement, such as the ones occurring during earthquakes. Scientists developed an early warning system to determine when an earthquake is going to take place by analyzing the behavior of two types of waves: P waves and S waves. P waves are the ones that travel faster and are produced first, they travel in an exact opposite direct of where the earthquake is produced. On the other hand, s waves or secondary waves are slower and travel in a perpendicular way. Scientist detect when these waves are generated in specialized centers.

I really need help w this question. There is more than one right answer.

Let's refer to the statements as A through F.

A. The diagram shows the ocean absorbing "90" and releasing "88". That means the ocean absorbs more than it releases (90 > 88), so acts as a "sink", a place where carbon is stored. (TRUE)

B. The dashed red arrow on the right labeled Fossil Fuel Combustion shows a transfer of carbon into the Atmosphere. (TRUE)

C. The diagram shows "Primary Production and Respiration" as coming from "Vegetation and Soils", so animals are not the sole contributors of CO₂ from respiration. (FALSE)

D. The blue arrows show exchange of atomospheric CO₂ with oceans and land. (TRUE)

E. While "Changing Land Use" contributes a net decrease of atmospheric CO₂, that is more than balanced by "Combustion and Industrial Processes." The net "Anthropogenic flux" appears to be positive into the Atmosphere. (FALSE)

F. The blue arrow into Vegetation and Soils is 120, the blue arrow out is 119, so soils take in more CO₂ by natural processes than they release. Likewise, "Changing Land Use" contributes a net increase in CO₂ in the soils and vegetation. Hence, soils do take in more than they release. (TRUE)
