Answer:
b. active transport
Explanation:
Active transport - 
It is the movement of the molecules across the membrane via a region of lower concentration towards the region of higher concentration , and in some cases , the flow is independent of the concentration .Its is known as active transport .
This process needs some amount of energy in the form of cellular energy .
Hence , the correct term for the given statement is active transport .

What is the backup energy molecule that can be rapidly converted to ATP in active skeletal muscle?
The answer would be D. Phosphocreatine, because phosphocreatine plays a major role on energetic homeostasis in both active skeletal and cardiac muscles. Phosphocreatine is basically creatine but phosphorylated, and that is why it has such a name. It has the role of turning ADP (adenosine diphosphate) into ATP (adenosine triphosphate).
Remember, ATP is the currency of life! That is what my biology teacher taught me.
 
        
             
        
        
        
The correct answer is B
The genetic codes language in all living organisms is the same. This is to say that the molecules of life namely DNA and RNA share the same make up in all living things .
There are five types of nucleotides in nature which are the building blocks of RNA and DNA and these are the same in all living organisms . These nucleotides are Adenine, Thymine, Guanine, Cytosine and Uracil.
According to base pairing rules, in all DNA molecules Adenine will always pair with Thymine while Guanine will always pair with Cytosine. 
This  rule is the same with RNA except that here Thymine is replaced with Uracil.  Otherwise the base pairing rule applies in all living organisms, that is to say it is universal.
