Answer:
Option A, accumulate sulfur as intracellular granules.
Explanation:
Purple sulfur bacteria belong to the group of Proteobacteria. These probacterias are anaerobic in nature and yet are able to photosynthesise. They are usually found in water environments such as hot springs, stagnant water etc. They use sulphur (either in the form of sulfide, or thiosulfate) as an electron donor in their photosynthetic activity to oxidise sulfur thereby producing granules of elemental sulfur.
while filamentous sulfur oxidizers use nitrate instead of oxygen to oxidize sulfide thereby producing granules.
Hence, option A is correct.
Answer:
Here you go :)
Explanation:
Plant roots complete a cycle in the soil. The deeper they go, the more benefits they provide to soil fertility and stable carbon storage in soils. While alive and active, roots redistribute carbon and nutrients throughout the soil profile.
I’m pretty sure it’s D, sorry if I’m wrong, I looked it up and it said “ Speed, latitudes, and direction of the objects determines the path along, which, the Coriolis effect deflects moving objects”
Answer:
An adequate sample of a population for studies of natural selection should
be large enough to:
represent the genetic variation in the population
Explanation:
Wind-driven waves are created by friction between wind and surface water. When wind blows across the surface of an ocean the continual disturbance creates a wave crest. These waves can be created through local winds or distant winds. The waves can be affected by wind speed and wind duration. The faster the wind and the longer it blows, the bigger the waves. It also can depend on how far the wind blows uninterrupted.
I hope this helps :)
