Answer:
Examples of vestigial structures include the human appendix, the pelvic bone of a snake, and the wings of flightless birds. Vestigial structures can become detrimental, but in most cases these structures are harmless; however, these structures, like any other structure, require extra energy and are at risk for disease.

Answer:
An RNA single-stranded molecule that is complementary to one of a gene's DNA strands, to be precise.
Explanation:
DNA sequences or segments code for proteins or molecules with defined functions, called genes.
The type of stimulus following a behavior removes something that is unpleasant is the negative reinforcer.
Stimulus is any signal. This can be in the form of touch, smell, taste, etc. This stimulus triggers the nerve cells of the body that send to signals to the brain to generate a response. For example, when one person touches a hot utensil, the touch of heat acts as a stimulus, where the brain sends response in the form of instantly removal of the hand.
Negative reinforcement is the response towards a stimuli that has not yet been received. For example, taking a medicine before any disease appears is the acts of negative reinforcement.

Answer:
The correct answer is - CNN.
Explanation:
Protein modification or folding takes place in the endoplasmic reticulum. The Endoplasmic Reticulum modifies the amino acids according to their signal sequences and tail. The following case can help in indicating the C-terminus (C) or the N-terminus (N) of each of the following proteins-
A) the C-terminus would be placed in the cytosol and the N-terminus in the endoplasmic reticulum lumen after cleaving the N-terminal signal sequence.
B) The N -terminal is the positive end of the chain and as per the rule of positive inside it allows N terminal in the cytosol
( C ) Tail-anchored proteins always have their N-terminal bulk in the cytosol.
Thus, CNN would be the correct answer from the explanation given above.
