Which of the following statements about M protein is FALSE? Which of the following statements about M protein is FALSE? It is found on fimbriae. It is readily digested by phagocytes. It is found on Streptococcus pyogenes. It is a protein. It is heat- and acid-resistant.

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 Streptococcus pyogenes. 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.

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
