Explanation:
this scientist has to inoculate the parent population using plates that contains penicillin in them. we call this approach the direct selection.
In the direct selection, bacteria is grown on a material that has penicillin in it. the goal is to find mutants that have resistance to penicillin. only these resistant ones would grow and then a direct identification would be done.
<span>The answer is b. Angiosperms. Bryophytes are seedless plants. Gymnosperms and Angiosperms have seeds. The difference between these two groups is in the seed position. If seeds are inside ovaries, a plant belongs to Angiosperms. If seeds are outside ovaries, on the scales for example, a plant belongs to Gymnosperms. Since apple flowers produce seeds inside ovaries, it belongs to Angiosperms.</span>
Nitrogen and Iron
Dissolved nutrients is one of the most important property of sea water and has a huge effect in life in the ocean. The most critical is nitrogen among the nutrients. This plays a major role in the stimulation of the primary production by the planktons in the ocean. This can be considered as limiting because most marine life cannot live without this nutrients. Nutrients in the ocean are cycled to keep the balance known as biological pumping.
