Answer: D. some components of the cycle are used as building blocks for certain anabolic pathways.
Explanation:
The citric acid cycle or Kreb's cycle is the part of the cellular respiration. It is a sequence of chemical reaction which is used by all the aerobic organisms so as to store energy by the process of acetyl CoA oxidation derived by the process of fats, proteins and carbohydrates into forms like carbon dioxide and adenosine triphosphate (ATP).
The acetyl CoA is used in the process of synthesis of fatty acids. The citrate is used for the synthesis of cholestrol. The oxaloacetate and alpha ketogluterate are used for the synthesis of aminoacids. Succinyl CoA is used for the synthesis of poryphrins and fatty acids. 
 
        
             
        
        
        
Answer:
b. although some primates have the ability to transmit meaning from one individual to another, this always happens within a species, never between species; this is similar to humans, since humans do not really understand other animals either.
Explanation:
Transmission of information or message often takes place between species of same kind. 
Human can better understand the language, sounds, signs made by fellow human and not sounds from other species of animals or other organism, this is because language or system of communication is attached to a particular domain or organism of a species. Birds communicate differently from a Goat, human does likewise from other primates.
The system of communication is used to a particular locality and if not learned it is not understandable by another species of organism.
