The best answer to this would be Proterozoic (although it actually lasted a little less than half by estimates, but it's the longest period.)

It started around 2500 million years ago and lasted till 500 million years ago- 2000 million years long. The estimated age of Earth is 4500 million years old -a little over twice this period

The professor Bonefinder has made a mistake.

Explanation:

I't is true the Hominoid had a long snout, a large orbits that are partially enclosed, but they have no tail. This point is really critical because the morphology of an species is really important. The taxonomists use the information that morphology gave for many years to identify species, nowadays with molecular techniques some of those species are pulled apart, but the important matter is that hominoids had no tail.

So the professor Bonefinder analysis is incorrect because the hominoids have no tail.

2. True or False<br> Ice is less than dense than water.
seraphim [82]

Answer. True

Explanation:

When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.
