a runner dashes 234 m in a direction due north from the starting line (xi = 0 m). she then turns around and runs due south back toward the starting line 65 m.
if both legs of this run take a total of 220 seconds, to the nearest meter, what is her total distance traveled?

answer: the total distance traveled is 403m. she runs 234m in one direction, and runs back to the 65m mark, which is 169m from the 234m mark she reached. 234+169=403

hope this : )

In a DNA (Deoxyribonucleic Acid) strand, the nitrogenous bases, namely the adenine (A), thymine (T), guanine (G), and cytosine(C) keeps the strands together. The complementary bases forms hydrogen bases with each other. Adenine is complementary with thymine, and guanine is complementary with cytosine. Hence, the complementary strand of the DNA strand with sequence ATCGGC will be TAGCCG.

Hence, the correct answer is option (c).
