Answer:
Random mutations led to evolution of pesticide resistance genes in bed bugs.
Explanation:
Random mutations in genome of bed bug imparted them the pesticide resistance. Since the bed bugs having the mutation of pesticide resistance were able to survive under presence of pesticides, this variation was favored by natural selection. The bugs with pesticide resistance transmitted this trait to their progeny. In time, the bed bug population consisted of most of the bugs having the pesticide resistance.
Answer:
All of the above.
Explanation:
Jealousy is the emotional state of feeling jealous. This is more of a negative aspect rather than a positive one, but can also sometimes be a positive aspect in a relationship.
Jealousy incites the person to have negative feelings like anxiousness, wrath, anger, possessiveness, excitement, etc. But it can also lead to an increase in the passionate feelings for the other person, which can make the individual pay more attention to the other person. In this aspect, it becomes a positive thing.
Thus, the correct answer is all of the above.

Answer:
Normal Gene: AUC AUA GGA AAA UAC
Mutated Gene: AUC ACA GGA AAU UAC
Explanation:
The transcription takes place in the nucleus. This process involve copying of DNA sequence into mRNA (messenger RNA) sequence. mRNA too consists of 4 nucleotides except the fact that in mRNA the thymine (T) is replaced by uracil (U). This involves the following steps:
- Unwinding of DNA
- Binding of RNA polymerase to the unwinded DNA.
- Synthesis of RNA commonly mRNA
- RNA elongation
- Stop codon (UAA, UAG, UGA) initiating termination of synthesis of RNA
