Answer:
Their ability to manufacture their own food
Explanation:
There are two main types of plankton. this includes phytoplankton and zooplankton. Phytoplankton are different from zooplankton in that these plankton are plant-like and undergo photosynthesis manufacturing their own food. They are also regarded as being autotrophic. They are important in that other organisms including the zooplanktons depends on them for food, hence they can also be categoriZed as producers.
Answer:
A. Evolution
Explanation:
Natural processes like speciation create variation in species, making them have biodiversity and a diverse gene pool.
Gradualism also allows for species to change gradually over time.
Both of these processes allow for evolution to occur, as speciation can create more favorable traits that will be passed down with the process of gradualism.
So, the correct answer is A, evolution.
Answer:
Mutations in introns create alternative splicing site which in turn make mRNA with reduced or no translation.
Explanation:
Introns regulate the splicing of heterogenous RNA during post transcriptional modifications as well as affect the stability of mature mRNA. The stable mRNA is more likely to be translated into proteins. So, introns also regulate the translation of mRNA.
In human beta thalassemia, mutations in intron create alternative splicing sites which in turn affect the formation of beta globin chain of hemoglobin. Lack of beta globin chain reduces the amount of functional hemoglobin and causes anemia.
