Which of the following is an example of primary succession?
kiruha [24]

Answer:

B. the appearance of lichens and mosses in an area where a glacier has recently melted away

Explanation:

Ecological succession, which refers to the series of changes that occurs over time in an ecosystem, can be of two types namely: primary succession and secondary succession.

Primary succession is a succession that involves an area where no form of life has grown previously, hence, the area of land is barren e.g bare rock. Primary succession is first colonized by species called PIONEER SPECIES e.g. lichens, mosses etc.

According to this question, "the appearance of lichens and mosses (pioneer species) in an area where a glacier has recently melted away" is an example of PRIMARY SUCCESSION.

The operon model of the regulation of gene expression in bacteria was proposed by _____.
AlladinOne [14]

Answer: D. Jacob and Monod

Explanation:

An operon is a region of DNA that consists of a single gene regulated by more than one promoter. An operon is a region of RNA that consists of the coding regions of more than one gene. RNA polymerase is the enzyme that binds to promoters and transcribes the coding regions of genes into RNA.

Jacques Monod was the first to demonstrate the preference for certain substrates over others through his studies of E. coli’s growth when cultured in the presence of two different substrates simultaneously.
