Answer: Option C
Explanation:
Amino acids are the polymers that leads to the formation of the polymer proteins. The amino acids are joined together by the polypeptide bond.
In case of sugars the simple sugars are joined together by the glycosidic bond to form a more complex structure known as starches. The simple sugars are easily digested and are less complex in terms of bonding and structure.
Cellular respiration is a process that converts glucose and other chemicals and substances into ATP (energy used by the cell). This is important because if we didn't have cellular respiration, we would not have energy to move our bodies and die off.
A goes with T and G goes with C
Answer:
c. endosymbiosis requires high oxygen concentrations for evolution to proceed
Explanation:
Endosymbiosis is an hypothesis which stipulates that complex organelles like mitochondrion and chloroplast evolved as a result of symbiotic relationship between aerobic, single cell prokaryotes in which an aerobic organism ingest an anaerobic organism in an atmosphere containing oxygen.
The oxygen in the atmosphere is like a poison to the anaerobic prokaryote and the ingestion by aerobic prokaryote protects it from the toxic effects of oxygen and in return, the ingested organism offers some benefit to its host resulting in a beneficial relationship.
Hence, the presence of oxygen is important for endosymbiosis and eventual evolution of complex organelles in multicellular organisms.
The correct option is c.
