Hi!
I’m not 100% sure but I think it is the global warming since increased reenhouse effect leads to a warmer climate and that’s what the global warming is.
Anyways, I hope it helped!
<span>It has to be made bioavailable by cyanobacteria. This process is called "nitrogen fixation" and involves the conversion of atmospheric nitrogen (N2) into ammonia (NH3). This means that the nitrogen is reduced, in chemical terms.</span>
Explanation:
A gas can be converted into a liquid by increasing the pressure & decreasing temperature. So that the condensation occurs. You must also make the molecules closer so that it is a phase change from a gas to liquid. In liquids, the molecules are very near than that of gases.
<u>Cross-sectional </u>research method
Explanation:
The cross-section research design is most widely used in healthcare based researches. It is type of descriptive research based on observational studies.
This research is usually done on a group of people and provides both qualitative (descriptive interpretations) and quantitative (statistical interferences) details.
This research is not a relational type of research and hence cannot be used to study, relate or compare about individual changes. The experiences, values, changes observed in individual cases are not taken into consideration.
For example, it is used to study a disease like cancer in a certain group or a population-based on variables like different sex, age religion, ethnicities, location etc of various people. It is not used to study about cancer in an individual person.
It is also not the causal type and cannot be used for cause and effect type of researches. Manipulation of variables is not possible with this research design.
