Answer:
B. Humans and chimpanzees share a relatively recent common ancestor.
Explanation:
Both the humans and Chimpanzees are the primates that are they belong to the same group called hominids and genus called Homo.
When the DNA sequences of the Chimpanzees and the Humans are sequenced and compared than they showed that 98% of the genome is similar.
In the given question, the single strands of the humans and the chimpanzees base-paired which showed that 98% of the nucleotide sequence is the same. The most possible reason for this similarity is that they both were evolved from the common ancestors and they diverged recently in the past.
Thus, Option-B is correct.
The Explanation based on the meaning of abiotic and understanding of the characteristics of life is that:
- Abiotic factors are nonliving.
- Living things are said to have cells.
- Abiotic factors are factors that cannot have cells.
<h3>What are the characteristics of life?</h3>
They are:
- They have cells
- They make use of energy
- They Reproduce
- They Respond to the environment
- They do grow and develop
Abiotic Factor are said to be the those environmental factor that is said to be dead (not living) and are those which has never lived.
Therefore, The Explanation based on the meaning of abiotic and understanding of the characteristics of life is that:
- Abiotic factors are nonliving.
- Living things are said to have cells.
- Abiotic factors are factors that cannot have cells.

Answer:
D. They block communication between enhancers and non-targeted promoters
Explanation:
Insulator sequences are the group of DNA sequences that protect the protein-coding regions of the DNA from the surrounding regulatory sequences. Some insulator sequences are present between the enhancers and promoters of a gene. These insulator sequences do now allow these enhancers to regulate the expression of genes by sending inappropriate signals.
However, if the insulator sequences are not present between the enhancers and promoters of certain genes but are located somewhere else, enhancers can upregulate the expression of these genes.
