Answer:
During the Cambrian explosion approximately 535 to 525 million years ago, 2. animals rapidly diversified in the oceans
Explanation:
Scientists have the theory that the Cambiran explosion, approximately 535 to 525 million years ago, <em>was possible because of complex predator-prey relationships and increased atmospheric oxygen levels.</em> All this situation promoted animal diversification. Thinking about evolution, animals directly evolved from protists.

Ice is less dense than water
Explanation:

Coral reefs are built by coral polyps as they secrete layers of calcium carbonate beneath their bodies. And inside each coral poly lives single-celled algae called zooxanthellae. So basically in simplistic terms, coral polys create coral reefs and algae is in coral polys which also goes into coral reefs when they are made.
Answer:
X∈R
and
f'(x)=0
Explanation:
Find the domain:
f(x)=-2×1
The domain of a constant function is the set of all Real numbers.
x∈R
Find the derivative:
f(x)=-2×1
Find the derivative of the function.
f'(x)=
(-2<u>×1</u>)
Any expression multiplied by 1 remains the same.
f'(x)=
(<u>-2</u>)
The derivative of a constant is always 0.
f'(x)=<u>0</u>
because you know, i mean you know.
