Answer:
RNA
Explanation:
CRISPR system was discovered by a Japanese scientist. Naturally <u>bacteria and many other prokaryotes</u> have <u>CRISPR system in their genome</u> which they use as a<u> self defense against a pathogen</u> which is invading them. It consists of<u> inter spaced, short palindromic nucleotide repeats </u>which <u>encode a guide RNA (gRNA)</u>. This guide RNA (gRNA) recognizes the<u> target sequence</u> on the pathogen. The <u>gRNA is followed by Cas9 enzyme</u> which along with the gRNA plays a very important <u>role in breaking genome</u> of the pathogen. Once the target gene is cut down the rest of the DNA can be rejoined by<u> non homologous end joining. </u>
But nowadays, scientists are using this system for <u>genome editing</u> and <u>incorporating desired gene</u> between the two ends which are cut down by <u>CRISPR Cas9 system.</u>

100 because it’s had to give energy to the rabbit to get eaten by the hawk
Answer:
I believe the answer is c
Explanation:
By breaking down the bonds in glucose in the presence of oxygen, energy<span> is produced in order to add a phosphate group to ADP to form </span>ATP<span>. In this way, 38 ATPs are formed. This process is called cellular respiration. ... When this bond is broken, adenosine diphosphate, or ADP, is formed</span>
