Answer:
the conversion of sunlight energy into chemical energy
the process by which plants, some bacteria, and some protist use the energy from sunlight to produce sugar
Explanation:
<em>Photosynthesis is a process during which the energy present in the sun is converted into chemical energy and locked up in an organic compound. The energy from the sun is trapped by the chlorophyll - a compound found in green plants, some bacteria, and some protists - and utilized to synthesize sugar along with inorganic materials such as carbon dioxide and water. </em>
The entire process of photosynthesis consists of multiple steps whose chemical equation can be summarised below:

Answer:
Sample Question: What is the effect of molecule size on a molecule's ability to diffuse across a semipermeable membrane?
-format: “What is the effect of X on Y?”
-independent variable: molecule size
-dependent variable: the ability to diffuse across a semipermeable membrane
The new hypotheses proposed by different scientists are often criticized by the others because these new hypotheses contradict the ideas and hypotheses that already exist. Adapting one's mind to a new hypotheses explaining a past event is often difficult when more clear hypotheses were already given earlier. Thus, the hypotheses suggesting the extinction of the dinosaurs are difficult for the scientific community to accept.
