D. Pairs Uracil with Adenosine instead of Thymine.

The right answer is D

Both nucleic acids are composed of nucleotides but some differ.  

The DNA strands are composed of four nucleotides: Cytosine (C), Guanine (G), Adenine (A) and Thymine (T).  

The RNA is also composed of four nucleotides: Cytosine (C), Guanine (G), Adenine (A) and Uracil (U) (instead of thymine).

Bacteria grow in a culture at a rate proportional to the amount present. Initially, 300 strands of the bacteria are in the cultu
OLEGan [10]

Answer:

(a) number of strands (n) = time (t) ÷ proportionality constant (k)

(b) The time needed for the bacterial to double its initial size is 3.36 hours.

Explanation:

(a) Let the rate (time) be represented by t and the amount (number) of strands of bacteria be represented by n

t is proportional to n, therefore, t = kn (k is the proportionality constant)

Since t = kn, then, n = t/k

(b) Initial amount of strands = 300

Amount of strands after 2 hours = 300 + (300 × 20/100) = 300 + 60 = 360

k = t/n = 2/360 = 0.0056 hour/strand

Double of the initial size is 600 (300×2 = 600)

Time (t) needed for the bacterial to double its initial size = kn = 0.0056×600 = 3.36 hours
