Like DNA, RNA follows base-pairing rules. Experiment to find which RNA on the right side of the Gizmo will successfully pair with the thymine at the top of the template strand of DNA.

Nucleotide; Adenine

Explanation: RNA Nucleotide contains bases of Thymine, Cytosine, Guanine and Uracil. The Uracil base in RNA, substitute the base Thymine in the DNA base and bonds with Adenine like as seen in DNA base pairing.

Thus, during DNA duplication, the thymine at the top of the template strand of DNA is replaced with Uracil and binds with Adenine.

c. live where it’s cold and icy

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
