The correct answer is sponges.

Why sponges develop first?

Sponges belong to the oldest and most simple animals that had evolved, and their discovery in such old rocks meant that they may have been the first animals.

you think this is limiting? How could this affect scientists search for life beyond Earth?

Answers

Answer:

I think there is life beyond earth. Actually there most definently is. I think in  a way it could be limiting. It's the fcat that the ones out there may not even be able to receive the message as fast as we please. Who knows, it could be years, decades, maybe centuries before they make actual contact with us. Then again, maybe they already have. But, the way this could affect the study is the fact that (I doubt it) but maybe a message could be sent the wrong way, or they misinterpret it. That's the only think I can get off. Anyway, this can also depend on how much funding is going into space. This also brings up the question, "How much do we know about our own planet?

An interglacial is a period of time that occurs between Ice Ages. During previous interglacials, the CO2 levels in the atmosphere were about 300 parts per million (ppm). In 2013, they were approximately 420 ppm. Rounding to the nearest percent, what is the percent increase in CO2 between these two time periods?

Answers

Answer:

40% increase

Explanation:

Percentage Increase Formula:

Percentage Increase=[(Final Value−Starting Value)/|Starting Value|] ×100%

To Calculate Percentage Increase:

   1) Subtract final value (later value) minus starting value (initial value)

  2) Divide that amount by the absolute value of the starting value (initial value)

  3) Multiply by 100 to get percent increase

Keep in mind: If the percentage is negative, it means there was a decrease and not an increase.

So for your problem,

[(420-300)/300]*100% = 40% increase

Any variable term, when it is cubed, always has an exponent divisible by 3.Miguel is correct. Any monomial can be a perfect cube root because, when it is cubed, the variables will have exponents divisible by 3.Sylvia is correct.
