The endosymbiotic theory is something that attempts to explain<span> the </span>origins of Eukaryotic cells <span>or ganelles such as mitochondria in animals and fungi and chloroplasts in plants was greatly advanced by the seminal work of biologist Lynn Margulis in the 1960s.</span>
The plasmid is an extrachromosomal DNA molecule that is not part of the bacterial genome. Plasmids carry genes that benefit the survival of the organisms. For example, antibiotic resistance. The plasmid is transmitted from one bacterium to another through conjugation. Transfer of genetic material is the mechanism of horizontal gene transfer and plasmid are considered as part of mobilome, unlike viruses where plasmids are nacked DNA.
For plasmids to replicate independently with cell must possess stretch of DNA that acts as the origin of replication. Self-replicating of the plasmid is called replicon.
<span>Other factors found within its environment can make pioneer species still germinate and thrive. Factors like wind, presence of animals, rain, among others, can help in the germination of the pioneer species even if its immediate environment becomes inhospitable through time.</span>

Answer:
C. Pepsinogen is the active form of pepsin.
Explanation:
Pepsin is a gastric protease belonging to the aspartic proteinase family which breaks down polypeptide chains into smaller peptides by hydrolyzing peptide bonds. Pepsin is found in the gastric juice where it digests proteins from foods together with other digestive enzymes and hydrochloric acid. Moreover, pepsinogen is a precursor of pepsin which is secreted by the gastric chief cells of the human stomach and then is converted into pepsin (its active form) by hydrochloric acid.
