It is crucial to study ocean microbes because THEY CONTROL THE MAJOR BIOGEOCHEMICAL CYCLES THAT KEEP EARTH'S BIOSPHERE IN BALANCE.
The ocean is made up of many microbes, which play important role in the process of biogeochemical cycling of various elements. For instance, microbes play very important role in the biogeochemical cycling of carbon and nitrogen. In the nitrogen cycle, the microbes are responsible for breaking down the protein molecules that are found in the body of dead plants and animals. The proteins are broken down into constituent amino acids, which are then released back into soils. The soil used these ammonia as sources of nitrogen for growing plants.
Answer:
F
Explanation:
Vesicles deliver protein to the golgi apparatus to be synthesized.
Answer:
A Mutation is an agent of substance that can bring about a permanent alteration to the physical composition of a DNA gene such that the genetic message is changed.
Explanation:
Answer:
(2) low power: 100 small pollen grains
high power: 25 large pollen grains
Explanation:
Compound light microscopes are devices used to greatly magnify objects. They have several objective lenses, a low-power lens magnifies 10 times (10X) the objects, and the high-power lens magnifies them 40 times (40X).
For that reason, when observing the pollen grains with the high-power lens the student will see them bigger than with the low-power lens. However, the field of view (the visible area through a lens) is reduced when a higher power lens is used, so fewer pollen grains will be seen.
The answer therefore is the option of higher number of pollen grains of small size for the low-power lens, and lower number of pollen grains of larger size for the high-power lens.
