Biology is a very important thing in life it helps us understand what all other living creatures live and what they do to survive and that will lead us to ideas to help us understand about living creatures
Science means to know. Biology is the study of living things. You understand a lot more of the function of the body (EMT, healthcare, diseases, etc.) animals (veterinary work,etc.) You will understand the intro into genetics, and the ways in which the sun and plants directly influences our entire world. Biology is a form of science that is pretty broad, and at the same time a form of science you can use in every day life of understanding the basic things that happen around you (in culture, family, news, environment, behavioural, etc.) Biology is also a great way to get your feet wet into basic science- a launching pad for chemistry, physics, etc. Hope this helped. :)
Well a person can be asymptomatic for loads of viruses not just coronavirus. There is no way of knowing if someone is asymptomatic without having a test done. Many asymptomatic people will go on to get a test and then show symptoms a few days or so later.
