It is crucial to study ocean microbes because _______. a. they control the major biogeochemical cycles that keep Earth’s biosphe
re in balance b. they are a significant source of greenhouse gases and pollution c. they are frequently used as food sources in developing nations d. they provide a significant alternative energy source used to replace coal and oil
The correct answer is A. They control the major biogeochemical cycles that keep Earth’s biosphere in balance.
Explanation:
Ocean microbes include organisms such as bacteria, protists or archaea found in the ocean. These organisms are one of the most important factors for life in the ocean and on all the planet. This can be explained as microbes in the ocean clean toxins and wastes that might affect other living organisms, and serve as food for others. This is the case of plankton that is consumed by many fish in the ocean, and it is necessary for many multicellular organisms.
Besides this, microbes regulate multiple biogeochemical cycles that include regulating carbon levels, as well as other substances that are necessary for life such as nutrients, nitrogen or phosphorus. Thus, it is crucial to study ocean microbes because "They control the major biogeochemical cycles that keep Earth’s biosphere in balance".
Answer: This modern-day researcher used some of the same theories that Darwin proposed. Like Darwin and his finches and tortoises, this scientist understood that the Galapagos cormorants inherited flightless wings. Darwin eventually discovered that his Galapagos finches likely evolved from other species of finches on the mainland. This evolution was similar to how the flightless Galapagos cormorants evolved from other species of cormorants.
The answer is alleles detached from one another during
anaphase of meiosis I, when the homologous pairs of chromosomes separate. During
anaphase I, homologous pairs are drawn apart, and
they go in the direction of the opposites of the cell. Meiosis I finishes
with the manufacture of two haploid daughter cells for the reason that
the homologous pairs of chromosomes have been separated.
