Let's go through the choices!
A. They're unaffected by positive self-talk.
Let's pretend you are scared of thunder. If you tell yourself, "I will not let thunder scare me; it will not hurt me," you will be less scared! So, A is not the answer.
B. They're harmless, because they're imaginary.
If you are scared of something, it can damage your mental health, which is not harmless. So, B is not the answer.
C. They're a kind of negative self-talk.
Being afraid of something is usually due to an overexaggeration in your mind. So, C is a good answer.
D. They're a kind of positive reinforcement.
Being scared is not positive. So, D is not the answer.
The answer is C!
Hope I helped! :)

The X chromosome, being larger, carries many more genes than does the Y.
Answer:
Transposition to different chromosomes by the ancestral gene
Explanation:
Transposable Elements (TEs), also known as jumping genes, are genetic mobile elements which are able to move from one location to another on the genome. There are two major mechanisms of TE transposition: 1-cut-and-paste mechanism, where one particular TE is inserted into a new position on the genome without replication, and 2-copy-and-paste mechanism, where a new copy is generated and the original TE remains at the original genomic site. In this case, it is likely that new TE copies containing the ancestral (duplicated) gene have proliferated through the copy-and-paste mechanism.
