Hi the answer to this isD.hope this helps.
Answer:
30 minutes
Explanation:
Bacteria reproduce by binary fission, a process by which one parent cell divides to form 2 progeny cells. Because one cell produces 2 progeny cells, bacteria are said to undergo exponential ( logarithmic) growth.
As in the case of staphylococcus aureus, we start with 100 cells , and after 90 minutes number becomes 800 that means , firstly the cells doubled (100 x 2 = 200 ) after 30 minutes. Again after 30 minutes they doubled ( 200 x 2 =400 ) and again after 30 minutes they doubled (400 x 2 = 800). So in 90 minutes 100 cells became 800 cells.
Hence the generation time for S.aureus is 30 minutes.
Answer:
Option B
Explanation:
The presence of these structures in this stage may be a prediction of a common ancestor as these structures are not gills because they do not develop into gills in chicks and humans but being so similar to gill structures in fish at this stage in their embryo suggests that chicks and humans share a common ancestor with fish.
The benefits of artificial selection is that you've taken the traits that you desire from a plant or an animal that could benefit your own survival. (Much like our ancestors bred the highest/most efficient crops, leaving us in a good farming position today). However, the drawbacks of artificial selection is that you effectively destroy any natural selection or "survival of the fittest" thus reducing the gene pool. If a virus or bacteria was effective against a crop that we bred, it would destroy our entire farming industry (also works with animals that we breed).
