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.

What are the phrase options ??
Divergent evolution is when two different species share the same ancestral origins but have evolved differently whereas convergent evolution is when species with different ancestral origins have developed similar features.
In convergent evolution, two species that are not necessarily closely related develop similar features often as a result of adaptation to similar conditions.
Gary would perform the duty of <u>handwriting analysis</u> in civil justice more often than what he does as a criminal forensic scientist.
Gary is a police officer who is also a forensic scientist, working in the criminal justice system. This means he collects, analyzes fingerprints, examining blood spatter all to have evidence against a criminal. Know, he works in the criminal justice system meaning the government, which could be government law enforcers would need those evidence against an accused individual at a federal or state criminal court. On the other hand, in a civil justice system, citizens can bring lawsuits against one another.
Now he would like to work for the civil justice system, and for his experience as a criminal forensic scientist, he would fit handwriting analysis since handwriting analysis is also a forensic practice done for the purpose of providing evidence in court. But this time he would be assessing the identity of a person from their written documents where there are differences between writing samples instead of processing fingerprints.
In summary, Gary would perform the duty of handwriting analysis in civil justice systems assessing the identity of a person from their written documents.

Organisms that originated in a certain geographic region and can only be found in that region are said to be endemic.
Explanation:
Endemic organisms are taxonomic species (plants and animals) which originates and distributed only in specific geographic regions. This state of evolution is called endemism.
They are said to be native or indigenous to that particular region which can be an ecological habitat, an entire nation, an island, a mountain range etc. Certain parts are known for majority of their species being endemic like St. Helen Island, New Caledonia Island, Hawaiian Islands, Southern regions of Africa, and Australia.
The species becomes endemic to a particular region because of the presence of certain bio-geographical environmental qualities of that habitat which are favorable to that species.
When these conditions become unfavorable, then species becomes restricted leading to endangerment or extinction of the species.
Examples:
- Kangaroo - Australia
- Nilgiri Tahr, - Nilgiri Hills, India
- The Redwood trees of West Coast of the USA
- Plants like kalo, sumac of Hawaii
