L lol

Answers

Answer 1
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.

4) because he was vaccinated with cow pox pus.

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.

What should you do if your family thinks you are taking advantage of them?

Answers

Answer:

People-pleasers are those who never say “no.” They’re the people who sacrifice their own needs to help others, to their own detriment.

If you yourself are a people-pleaser, the good news is that you can get out of this harmful pattern as long as you put in the necessary work.

First, you need to recognize that there is a problem with putting your needs on the backburner and bringing others’ needs to the forefront.

Once you’ve made this important realization, you can then work on getting to the root of the problem: why do you have people-pleasing tendencies?

Finally, you can set your boundaries and work at maintaining those boundaries: do what you need and want to be doing, and then consider what you can/want to do for others.
