Answer:
C) 2.0 kb
Explanation:
It is given that out of the 4 nucleotides A, T, C & G each one has equal probability to occur at any position on the DNA molecule which simply means that the probability of occurrence of any nucleotide at a position is 1/4.
Also, it is given that probability of occurrence of either A or T at 3rd position is equal which means that the probability at that particular position will be 2/4 = 1/2.
Now, GA(A/T)TC is the DNA sequence where Restriction enzyme HinfI cleaves so the total probability of an average HinfI cleavage fragment will be = 1/4 x 1/4 x 1/2 x 1/4 x 1/4 = 0.00195 = 0.2 i.e. 2 kb.
The speed of a longitudinal wave will not be affected by the temperature of its surrounding. Base on the formula for the wave speed (applicable on longitudinal wave), wave speed ( speed in m.s 2) is equal to the distance of a wave (wavelenth in meter) travel over a unit of time (seconds) or wave speed is equal to distance of a wave times the frequency (hertz), temperature is not included in calculating the wave speed.

Explanation:
The universe becomes less dense as the universe expanses. Draw dots on a balloon and watch them as the balloon fills with air.
<h3><u>Answer;</u></h3>
D) India was a separate continent until forty-five million years ago.
<h3><u>Explanation</u>;</h3>
- <em><u>Continental drift serves as one of the evidence of evolution. Different kinds of animals and plants live in different parts of the world. This is true now, and it was true in the past. </u></em>
- Therefore, when a fossils of the same animal or plant is found on different continents, then that is evidence that those two continents may have been a single continent when those fossils were formed.
- Fossils show that the continents drifted because similar fossils were found where the continents were together millions of years ago.
