The scientist most likely found an RNA molecule. The RNA is a single-stranded molecule composed of many nucleotides.
The ribonucleic acid (RNA) is a single-stranded molecule composed of a long chain of consecutive nucleotides.
In RNA, there are four types of nucleotides, each containing one different nitrogenous base, i.e., Adenine, Uracil, Guanine and Cytosine.
In RNA, Uracil nitrogenous bases replace Thymine bases observed in the DNA molecule.

The answer is C. I which we didn’t have to type a 29 character response typing to fill up space.
Answer:
Tiltmeters and strainmeters measure subtle changes in ground slope and shape at volcanoes. .
Explanation:
Measuring tiny changes in the slope angle or "tilt" of the ground and the shape or "strain" in the earth's crust are time-tested methods for monitoring volcano deformation caused by moving magma.
Answer: D) Polygenic
Explanation: Polygenic inheritance describes the inheritance of traits that are determined by more than one gene. These genes, called polygenes, produce specific traits when they are expressed together. Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.
