Hello,
The answer is option D <span>sustains life and keeps body systems in good repair.
Reason:
The answer is D because protein is very important to the body because it fuels your body without protein you wouldn't be able to live. Its not option A because protein does not help you build muscles. Its not option B it doesn't keep your nails or your hair. Its also not C because protein gives energy not collagen.
If you need anymore help feel free to ask me!
Hope this helps!

"Please be here at 7:00 a.m. tomorrow" is the most clearly stated. It states a clear hour to arrive, indicates whether arrival should be morning or evening, and what day arrival should be. This gives clear information to the person receiving the information.
Hope this helps!

There is proof of it. Such as fossils, records, videos, etc. Dinosaurs and Thylacines for example. Both of these have been extinct for quite some time. Although there is footage of some Thylacines there isn't any of any Dinosaurs. However, there is fossils and bones found from Dinosaurs. There has been fossils from many extinct animals dating back millions of years, therefore proving its a common event through history.
