The organic compounds that scientist use to cut, copy, and move segments of DNA are enzymes.

Explanation:

During the process related to DNA, the organic compound which is used in the process is called as enzymes. For each steps in the process, enzymes are employed. In order to cut the DNA into small pieces, a enzyme called restriction enzymes are used.

For copying the required DNA sequence, polymerase is used and to join the segmented DNA into a single strand DNA, ligase is used. All the three organic compounds used in the process are nothing but enzymes.

the way that the mass of carbon can be conserved through cellular respiration is through a process/law called the law of conservation of mass which even tho it undergoes a process, mass is not be destroyed or changed

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
