Answer:
In nature, the oxygen element mainly occurs in gaseous form. While hydrogen is also formed of two atoms and is also a colorless, odorless gas just like oxygen. But hydrogen is generally found as water.
Explanation:
Oxygen and hydrogen are commonly diatomic molecules, not compounds. Hydrogen is the most abundant and light of all elements in the earth. Hydrogen reacts with oxygen to form water. Hydrogen too forms parts of many compounds such as acids, hydrocarbons in organic compounds and so on. About 10% by mass of human body is composed of hydrogen. Oxygen, as it already known is the elements responsible for the survival of living organisms. It forms about 65% of human body by mass.

Answer:
A sample size of 300 people.
Explanation:
The answer is "a sample size of 300 people".
Usually, the sample size has a significant impact on the accuracy of any study. If The sample size is larger, the result will be better. It is said here that the sample size was only 300 people. Marcus is necessarily indicating that he has a limited window of insight. It means it's showing the limitation of the study. If the sample size were larger than 300, the result would be more accurate.
For this reason, Marcus wants to repeat his research with larger sample size.
