Answer:
There was no sulfur compound added to the medium, that could be used as an electron donor.
Explanation:
Bacteria that use light for energy requirements mean that they get their energy from photosynthesis and transferring energy through the molecules.
Bacteria play a major part in the reductive and oxidative cycle of the sulfur which is mediated by the help of photosynthetic bacteria, so the sulfur or sulfur compounds are major requirements for their growth in the habitat or the medium.
Thus, the correct answer would be- There was no sulfur compound added to the medium, that could be used as an electron donor.
After mining, to reclaim the land, the depression is filled with rocks then the top is filled with loosely graded soil. Introduction of early succession plants is important before big trees can grow. The early succession plants help in the breaking down of the rocks into soil hence making the topsoil deeper to support trees.
Answer:
C. Helicases
Explanation:
Helicases to be termed as enzymes that is blind and contains acid i.e. remodel nucleic or have protein i.e. nucleic acid. It is important as the time of DNA replication as it divided the DNA i.e. double stranded into one single standard that permits each and every strand for copied it
Also it cracks the bonds i.e. hydrogen that lies between the two strands this could create a replication fork.
Therefore in the given case, the helicases is affected
When the structure and function of an organism adjusts to its environment it is adapting.
