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:
heterozygous purple pea plant and heterozygous purple pea plant
Explanation:
Suppose the gene controlling flower colour in pea is P. Allele P is dominant over allele p. So, PP and Pp produce purple flowers and pp produces white flowers. If two heterozygous purple pea plants (Pp) are crossed :
Pp X Pp :
P p
P PP Pp
p Pp pp
As evident, the progeny will have genotypic ratio of 1 : 2 : 1 ( PP : Pp : pp ) and phenotypic ratio of 3 : 1 ( Purple : white )
Hence two heterozygous purple pea plants will produce 3:1 ratio of purple to white pea plants.
