Answer:
a) Genes b and c are farthest apart.
Explanation:
Transformation occurs when a competent bacteria cell takes up genetic material from the environment. Usually a donor cell donates its gene fragment which is then incorporated into the chromosome or plasmid of recipient bacterial cell.
Cotransformation occurs when two genes are taken up together by the recipient. The closer the genes lie to each other, more are the chances of them being taken up together. Contransformation frequency will be higher if two genes are close to each other. Here, cotransformation frequencies between three genes are given. Amongst them, the lowest frequency is 0.0064% which is present between gene b and c. Hence, gene b and c are the farthest apart.
The correct answer is <span>C. You cannot view live specimens because the necessary preparation kills cells. </span>
The answer is pretty self-explanatory. Unlike it, regular microscopes can view living creatures such as bacteria or similar.
Answer:
A.
Explanation:
There is also much climate evidence supporting continental drift, most notable of which is glacial activity. Alfred Wegener investigated this field and found an anomaly in the Permo-Carboniferous ice sheet that was found through glacial till deposits to have once covered all the southern major plates.
Answer: Fewer bubbles will be produced because of fewer collisions of reactant molecules.
I believe its D. It becomes more difficult for the cell to get enough oxygen and nutrients.
