Answer 1

Immunity is the response of the immune system against foreign objects entering our body.​

$\bullet$ Most of the pathogens are present in our surrounding. Hence, we are susceptible to different diseases. But our body has some in- built defence mechanism, which protects us from the pathogens.
$\bullet$ This defence mechanism is our immune system. Immunity is the ability of an organism to recognize the disease-causing germs and provide resistance against them.​
