Answer:
c. sound
Explanation:
Matter is formally defined as being any substance that has any amount of mass and takes up space by having volume. Dirt, Humans, and Water all have a different level of mass and take up a different level of space. Sound on the other hand does not have neither mass or volume, it is instead a wavelength or a constant vibration that travels invisibly through the air. Therefore it is not composed of matter.

Answer and Explanation: GFP gene is a gene that encodes a green fluorescent protein. When bacteria and plasmid are combined, the gene is expressed as observed by the results: plasmid with GFP gene produces colonies with green color; while plasmid without GFP produces white colonies.
Ampicillin is an antibiotic, i.e., bacteria is naturally suscetiple to it.
Plasmid has an ampicillin resistant gene. This is demonstrated in the experiment: when there is plasmid, the gene can be expressed, allowing colonies to grow. But, when bacteria is not combined with plasmid, it is not resistant to the antibiotic, so no colonies are formed.
