The kind of lipid that forms when a glycerol combines with fatty acids through dehydration synthesis is the trigylceride. It is also known as a triacylglycerol. It is compound that is formed from a glycerol molecule and three molecules of fatty acid. It is synthesized by the reaction dehydration synthesis wherein water is the by-product of the process. The -OH from the functional group of glycerol are detached and the fatty acids would attach to it forming the triglyceride. A dehydration synthesis involves the combining of smaller molecules to be able to form a larger molecule and along with it water molecules are being released. It is also known as a condensation reaction.
Answer:
Changes in either the physical or biological components can alter the populations of many different organisms. These changes are called disturbances and can be either natural (volcanic eruption, drought) or man-made (increase in nutrient input by adding fertilizers, extinction of a species by habitat removal).

Hi. You have not shown the sections this question refers to, nor have you provided more information about those sections. This makes it difficult for your question to be answered. However, I will try to help you as best I can.
Generally speaking, we can consider that there was no growth of bacterial colonies in sections 2 and 3, because, for some reason, the bacteria was not inoculated in sections 2 and 3. What could also have happened, is that the bacteria in the sections 2 and 3 were eliminated, but the bacteria from section 1 managed to survive and form colonies.
Another possibility is that after inoculating the bacteria in section 1, you didn't handle the bacteria correctly in the other sections, leaving that bacteria to dry out and die.
Finally, the culture media in sections 2 and 3 could be inappropriate for bacteria to develop and form colonies.
