Answer: 23.8889
Explanation:
(75°F − 32) × 5/9 = 23.889°C
Molecules are cooler so they bocme more dense.. move very slow, have less kinetic energy and are not in random motion.
Answer:
The correct answer is "Fragment B likely has a higher Guanosine/Citosine content".
Explanation:
Guanosine/Citosine content, or GC content, refers to how many molecules of guanosine and citosine have a DNA fragment, respect to the content of adenine and thymine. The higher the GC content, the higher the temperature needed to denature the fragment of DNA. This happens because guanosine and citosine establish three hydrogen bonds, while adenine and thymine establish two hydrogen bonds when they bind together. Therefore, if fragment A and B are the same length, but at 89 C only fragment A is completely denatured, fragment B likely has a higher GC content.
Vectors include magnitude & direction so the third option is the correct answer :)
