Answer:
Hazel - 1/4 or 25%
Green - 1/2 or 50%
Blue - 1/4 or 25%
Explanation:
First, let us carry out the cross between AaBB and Aabb using a Punnet's square. The result is as below:
AABb - 4/16
AaBb - 8/16
aaBb - 4/16
(See the Punnet's square analysis in the attached image).
<em>AABb genotype has 3 pigments, hence, would be hazel.</em>
<em>AaBb genotype has 2 pigments, hence, would be green.</em>
<em>aaBb has one pigment, hence, would be blue.</em>
Expected progeny:
<em>Hazel - 1/4 or 25%</em>
<em>Green - 1/2 or 50%</em>
<em>Blue - 1/4 or 25%</em>
According to Jesse Kroll, an MIT professor of chemical engineering and civil engineering who specializes in atmospheric composition, the primary method used by scientists to quantify greenhouse gases in the atmosphere is spectroscopy. Thus, option A is correct.
<h3>What is the amount of carbon dioxide in the atmosphere?</h3>
Only 0.04% of the atmosphere is made up of carbon dioxide, and water vapor levels can range from 0% to 4%. However, while being the main greenhouse gas in our atmosphere, water vapor possesses “windows” that let some infrared light pass through without being absorbed.
Therefore, find a location outside with pure, unpolluted air, then use a special kind of flask to collect an air sample.

Answer:
four trophic levels
Explanation:
All food chains and webs have at least two or three tropic levels. Generally, there are a maximum of four tropic levels. Many consumers feed at more than one tropic level.
