Which succession occurs in a community that was never colonized before? a) secondary b) artificial c) temporary d) primary

Answer : The correct answer is -

D) Primary.

Primary succession can be described as a type of ecological succession that is started in an area where no life existed before, which includes regions that lack in soil or where the soil is not capable enough to sustain life.

The reason for this could be recent flow of lava, rocks that are left from a retreating glacier, or new sand

dunes.

Example - Formation of new island on a volacanic rock.

Thus, primary succession occurs in a community that was never colonized before.

individual oxygen atoms are formed during photosynthesis.-c.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
