Complex Ecosystem is all of the different types of plants and animals in an ecosystem
Answer:
Due to less steps and requires less energy.
Explanation:
The bacterial cell is able to use glucose first as an energy source then switch to lactose because glucose requires less steps and less amount of energy for the break down as compared to lactose. If lactose is the only sugar available to the bacterial cells, then bacterial cells will use it as energy source for the production of energy. In order to use lactose, the bacteria must express the lac operon genes, which encode the main enzymes for lactose uptake and metabolism.
Answer;
-COOH
Explanation;
The carboxyl group includes both a keto oxygen and a hydroxyl group; Carboxyl groups are weak acids, dissociating partially to release hydrogen ions. The carboxyl group (symbolized as COOH) has both a carbonyl and a hydroxyl group attached to the same carbon atom, resulting in new properties.
The carboxyl functional group is an acidic functional group frequently found in biological molecules. It is found in amino acids, proteins. fatty acids, acetic acids and other organic acids.
