1. The correct answer is A. Carbohydrates and fats are used for energy. For example, glucose, a monosaccharide carb, is used in cellular respiration to make energy.
2. It is not a carb or lipid as there is a Nitrogen. Your answer is Protein because it's showing an amino acid, the monomer of all proteins. There is an amine group, a carboxyl group, and R-Group. Therefore, it has to be C.
DDT was used to control the malaria-causing mosquitoes. DDT killed them but accumulated in the soil also, through which entered animals and humans via food. There, it gets stored in the fat tissue and is very difficult to breakdown. The predator animals, feeding upon smaller animals, got DDT in their bodies from the smaller animals and DDT thus, magnified to the top level of the food chain. The government realized this and banned DDT.

Glycolysis. ... Although glycolysis doesn't require oxygen, the fate of the pyruvate molecules depends on whether oxygen is present. If oxygen isn't available, the pyruvate is converted to lactate, and no additional ATP is produced from this conversion.
Answer:
The above statement is false.
Explanation:
Protozoans are not the organisms that can convert nitrogen from the air into chemical compounds that plants can use.
Bacteria and archaea are organisms that can convert nitrogen from the air into chemical compounds that plants can use. Organisms which can convert nitrogen to forms that can be used by plants such as ammonia are known as diazotrophs. Examples of such kind of organisms include Rhizobia and azospirillium.
