Hi. You have not shown the sections this question refers to, nor have you provided more information about those sections. This makes it difficult for your question to be answered. However, I will try to help you as best I can.
Generally speaking, we can consider that there was no growth of bacterial colonies in sections 2 and 3, because, for some reason, the bacteria was not inoculated in sections 2 and 3. What could also have happened, is that the bacteria in the sections 2 and 3 were eliminated, but the bacteria from section 1 managed to survive and form colonies.
Another possibility is that after inoculating the bacteria in section 1, you didn't handle the bacteria correctly in the other sections, leaving that bacteria to dry out and die.
Finally, the culture media in sections 2 and 3 could be inappropriate for bacteria to develop and form colonies.
Answer:
74%
Explanation:
The frequency in such cases (diallelic cases) is estimated by following formula which is attached in the image:
So as per our question, the frequency of the "R allele" as per data given below will be as under:
58 red-phase (RR)
32 cross-phase (RS)
10 black/silver-phase (SS) foxes
Total plants = 58 + 32 + 10 = 100
f(R) = 58 x 2 + 32/ 2 (58+32+10)
= 116 + 32 / 200
= 148/200
= 0.74 i.e. 74%
Answer:
Scientific theory definition, a coherent group of propositions formulated to explain a group of facts or phenomena in the natural world and repeatedly confirmed through experiment or observation: the scientific theory of evolution.
Explanation:
The answer is B. Natural selection will find a way to affect one, then that one will affect many others.
