The accumulation of ____________allowed organisms to grow larger.

Biology
1 answer:

       The right answer to this question is option A. O2 in the atmosphere.

       The main reason why it's a true that organisms would grow larger than we have today with more oxygen available is pretty simple to understand, their respiratory systems were smaller than we have today, and even though it was a small one, it was enough because of the higher presence and concentration of O2 in the atmosphere.

        Some studies were held nowadays to check this possibility, to see if the O2 was the real main reason for this, and the animals used in it really grew bigger than usual, so by that, they confirmed their hypothesis by testing it.

Potential Energy on the way up the rollercoaster
Nana76 [90]

Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.

hope this helps have a nice day❤️
