Answer:
My chemistry teacher from my sophomore year.
Explanation:
I took class online last year and he was an older teacher and really didn't know how to use a computer. I asked for help multiple times and he would tell me to look the answer up. I would watch countless videos and still wouldn't understand. He ended up failing me that year and I had summer school. To this day, I dislike chemistry because of him.
Answer:
The first claim is false. Natural resources can most definitely exist without synthetic products.
Explanation:
All synthetic products are derived from natural resources as everything has to come from a source in the beginning. However, most natural resources themselves are the source, make sense? For example, water is a naturally occurring resource, but even water is derived from specific components, however it doesn't need anything synthetic to exist. Now take hairspray, to make hairspray you need water and synthetic resources, see where I'm going with that?
These are electron dot diagrams.
They use dots arount the symbol of an atom to represent its <em>valence electron</em>s.
You will also see them called <em>Lewis dot symbols</em> or <em>Lewis diagrams</em>.
By comparing fossils of different primate species, scientists can study
how different species have diversified over time.<span> Almost all sediment is either laid down horizontally in
bodies of water like the oceans, or on land on the margins of streams and
rivers. Each time a new layer of sediment is deposited it is laid down
horizontally on top of an older layer. With this events, Geologists can
established a set of principles that can be applied to sediments and to
determine how these features evolved through time.</span>
