Answer:
They accurately compare the current atmosphere with the previous one, by assessing the amount of atmospheric gases present today, with the amount of atmospheric gases trapped in ice cores that they believe are millennial, that is, they have existed for thousands of years ago.
Explanation:
As we know, it is difficult to compare current characteristics of the planet earth with characteristics that the planet had in the past, thousands of years ago. This is because the ancient characteristics on earth are not fully available to be analyzed, since most of them have been modified over time.
To do this, scientists need to find factors that may have existed thousands of years ago and assess whether these factors have any account of the characteristics of the earth. In the case of atmospheric characteristics, it is common for scientists to compare the current atmosphere with the atmosphere of thousands of years ago, with the assessment of the amount of atmospheric gases trapped in ancient ice cores, with the amount of atmospheric gases present in the atmosphere today.
Answer:
A and E are the correct.
Explanation:
Examples of the structures that determine function:
a) <u>Chloroplasts </u>only found in plant cells. They work to fix the CO2 in the presence of <u>light energy</u> (sunlight) and convert the reactants into <u>sugar molecules (carbohydrates</u>) that can be used by cells for metabolic functioning.
e) <u>Sperm</u> is the male reproductive cell. Motile sperm cells have a tail-like structure that typically <u>move via flagella</u> and requires a water medium in order to swim toward the egg <u>for fertilization</u>.
Other options are not correct because <u>they don't explain their function according to their structure</u>.

Answer:
The most common elements, like carbon and nitrogen, are created in the cores of most stars, fused from lighter elements like hydrogen and helium. The heaviest elements, like iron, however, are only formed in the massive stars which end their lives in supernova explosions.
