       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.

Does the stomach only does chemical digestion to break down food?
bonufazy [111]
In the stomach, food undergoes chemical and mechanical digestion. Peristaltic contractions (mechanical digestion) churn the bolus, which mixes with strong digestive juices that the stomach lining cells secrete (chemical digestion). As food travels from your mouth into your digestive system, it's broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. This breakdown is known as chemical digestion.

What experimental evidence supports the model of metallic bonding?
Yanka [14]
Metals conduct electricity and heat, indicating that the electrons are free to move. Metals are malleable, showing that atoms are not in fixed positions but can remain bonded even though they change their positions. In metallic bonding, atoms donate electrons to a pool and all the atoms share in the pool. No compounds are formed, but the atoms are bonded into a network.
