Sample bias. It is a bias in that happens when a sample is collected in such a way that some members of the intended population are less likely to be included than others.
I just took the review the correct answer is D, I, II, III, and IV
The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.
<h3 /><h3>What is a random mutation?</h3>
Random mutations are just that, they are changes in the genome of an organism that arise randomly. These mutations are the backbone of evolution and natural selection in that when they arise, if the organism becomes more adapted to survival as a result of this mutation, it increases its odds of survival through natural selection.
Therefore, we can confirm that The Lederberg experiment that used the technique of replica plating showed that mutations are random and are not a result of the needs of the organism.

Answer:
birds
Explanation:
the T.rex has a lot of similar features as some species of birds, for example, the bipedal.
Answer:
Option (b).
Explanation:
Melting temperature may be defined as the temperature at which the DNA strand melts. The melting temperature depends on the Guanine and cytosine content of the DNA.
The thymine binds with Adenine with two hydrogen bonds whereas cytosine binds with guanine with three hydrogen bonds. More energy is required to break the guanine cytosine bonds and they have high temperature. The second strand 5'-ACGGCTACG-3' contains more GC content and hence have high melting temperature.
Thus, the correct answer is option (b).
