Yes
No that's not true. Science exist because of people's curiosexsity. Chemistry doesnt have to be nessesary.
I strongly consider that all mankind should have notions of chemistry. Also many relations exist between chemistry and biology.
Science is science, we only separate it into physics, chemistry and biology for convenience. Interestingly all three rely on one another: Good physics wouldn't exist without the scientific process. Good chemistry wouldn't exist without physics. Good biology wouldn't exist without chemistry. So really there is the following dependancy: Scientific Process > Physics > Chemistry > Biology
Because if biology didn't exist you couldn't breathe or have any things like houses and TVs and every day uses of tools.
There is no evidence that aliens exist therefore the biology of aliens, if they do, is unknown
Mermaids are mythical creatures because they appear in a variety of stories but do not exist in reality. They could not exist because they would be a contradiction of biology.
Marine Biology often requires travel internationally. Military doctors, or high profile doctors travel alot.
There are quite a few branches of Biology that someone might like most. Someone might like genetics the most for example.
Biology is important because you are alive. Human life is a shining example of what biology can do, without the forces that make us what we are we would be well nothing. Biology is the study of all of those forces, how to preserve them, and how to make them work for us. Biology is responsible for foods that spoil less often, cybernetic prostheses, and transplant able organs that can be grown from your body, for your body. Our modern world as we know it wouldn't exist without biology, and we all have everything to thank for it.
Fungi are just as essential to our biology as other microorganisms. Without them we would be lacking food and medicine.
