2) cowbox pathogens.

3) due to cowpox and smallpox being quite similar, the body was able to recognise the similar smallpox virus from its antigens and was able to fight the disease effectively.

5) He will not be infected by smallpox due to the vaccination he had from Jenner, who later on proved the immunisation by inoculating the boy with small pox 6 weeks later, which, had no affect later on in his life.

Afew buddies come over to your house to hang out. they notice you're struggling in school, perhaps you have to rely on to pass your class, but you can't absorb the knowledge. they could positively reinforce getting a tutor and working with you, dedicating more time to the areas of struggle and less on hanging out to better yourself.secondly, say you're the victim of bullying. you're afraid to tell an adult because of possible repercussions from the bully himself. your friends encouraging you and pushing you towards telling an adult for your safety is another example.
