Answer:

It is readily digested by phagocytes.

Explanation:

Virulence factors are protein and sugar molecules found on bacterial and viral surface that help them to gain entry and spread in host's body. They help to evade the immune reaction by the host and help in colonization in host's body.

One such virulence factor is M protein which is found on the surface of many species of Streptococcus, notably <em>Streptococcus pyogenes</em>. It is strongly anti-phagocytic i.e. phagocytes are not able to digest it. It evades phagocytosis by binding to fibrinogen found in host's serum. A structure is formed which inhibits the host's complement system to bind to the peptidoglycan cell wall of bacteria ultimately avoiding phagocytosis. Hence, M protein is readily digested by phagocytes is a false statement.

Which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts?
Zolol [24]

Mitochondria and chloroplast have similar DNA, which is not evidence for the endosymbiotic origins of mitochondria and chloroplasts.

According to the endosymbiotic theory, a chloroplast and a mitochondria were the independent prokaryotes. Both can be ingested by a large prokaryote and resist digestion. As a result, they continued as endosymbionts and eventually lost some of their autonomic properties. They divide by binary fission, have their own genetic material, possess 70s ribosomes, and Both include their own transcriptional and translational machinery.

Therefore, considering endosymbiotic origin theory, Both Mitochondria and chloroplast have similar DNA is not a piece of evidence.
