Answer:
Probably B
Explanation:
They all explain it, honestly, but B sounds the least like an answer they would accept as true. It's also kind of sus that they have 2 different answers about reacting differently to stress, and B is definitely the least likely of the two to be correct. Sorry I couldn't be more helpful, I'm only here because I searched for the answer myself. Good luck.
Carbon (C) is an element
Carbon Dioxide (CO2) is a compound
Hydrogen (H) is an element
Sodium Chloride (NaCl) is a compound
A good way to tell whether something is a compound or an element, is that in a compound there is a mixture of different elements. Like in Carbon Dioxide, the symbol is CO2. This shows the carbon (C) and oxygen (O) together. I hope i worded that well enough and this helps :)
Because people and animals exhale carbon dioxide which plants need and they release oxygen
If scientists wanted to learn more about evolutionary history, they would study all but one of these molecules. The biological molecule that would NOT offermuch information about the history of life is
<span>phospholipids
</span>the DNA proteins and nucleic acid will give them alot of information about history of life
so correct option is D
hope it helps
