Answer: The adaptations like paddy feet and fur on the outer body is an adaptation for very cold place but not for the rain forest.
Explanation: If the outer body of the organism is made of fur then it will protect the inside body from cold and will provide warmth.
But if the body will have adaptation like fur in the rain forest then it will make the organism wet so there will be no use of fur on the outer surface of the organism.
The adaptation like camouflage will help the organism in the rainforest so that it can hide themselves from predators in the forest.

Answer:
The correct answer is "proteins in which isoleucine is inserted at some positions normally occupied by leucine".
Explanation:
The missing options of this question are:
A. proteins in which leucine is inserted at some positions normally occupied by isoleucine.
B. proteins in which isoleucine is inserted at some positions normally occupied by leucine.
C. no abnormal proteins, because the ribosomal translation machinery will recognize the inappropriately activated tRNAs and exclude them from the translation process.
D. no proteins, because the inappropriately activated tRNAs will block translation
The correct answer is option B. "proteins in which isoleucine is inserted at some positions normally occupied by leucine".
In normal conditions, the enzyme leucyl-tRNA synthetase attaches one leucine amino acid to leucyl-tRNA as part of synthesis of proteins that have one or more leucine residues in their sequences. Since the enzyme of this mutant strain of bacteria mistakenly attaches isoleucine to leucyl-tRNA 10% of the time, approximately 10% of all the proteins that normally have leucine residues will going to have isoleucine. Therefore, These bacteria will synthesize proteins in which isoleucine is inserted at some positions normally occupied by leucine.
