Answer:
Friedrich Miescher discovered nucleic acids in blood cells.
Nuclein was discovered by Friedrich Miescher in 1869
Explanation
In the somewhat early 1880s Albert Kossel further purified the substance and discovered its highly acidic properties. Then he later discovered the nucleobases. In 1889 Richard Altman creates the term nucleic acid. Friedrich Miescher was the first scientist to ever isolate nucleic acid.
I also believe the answer is A.
Answer and explanation:
Monophyletic species are the species whose lineage belongs to the common recent phylogenetic ancestor. As mentioned in the question, the girl has 3 species namely G, H, and K. Because there is no other criteria given, we assume that the closeness of alphabets would reflect the closeness of species. Thus, G and H are closer relative than K. Therefore, if she adds <u>I, and J species</u> in the list, all of them will be closer relatives and we can say that they are monophyletic now.
First, there is a need to understand what the carrying capacity is as it relates to the environment:
- Carrying capacity refers to the maximum number of individuals of a particular species that and environment can support based on the resources it has.
- The population of a species in an environment grows and oscillates around the carrying capacity of the environment.
Now let us look at the graph. The population size grew from 0 and then leveled off at 2,000 with time. The leveling-off also happened without any oscillation, meaning that the maximum population size the environment can support is 2,000.
Hence, the portion on the graph that indicates the carrying capacity would be the plot where the population size is 2,000 and the time being between 12 and 18. This has been circled and labeled as 'K' in the attached image.
