For many years, whole or fragmented hominid skulls have been excavated.
Some of these skulls date from as early as 6 million years ago. By
comparing these skulls with other archeological findings, scientists are
able to determine when major accomplishments were successfully
achieved. Which of the following statements correctly states the
evolutionary progression of hominids?
Hominids first developed tools, then language. The brain got smaller.
Hominids first developed language, then tools. Brain size decreased.
Hominids first developed tools, then language. The brain increased in
size.
Hominids first developed language, then tools for farming. The size of
the brain increased.

Statement that correctly states the  evolutionary progression of hominids is that hominids first developed tools, then language and the brain increased in  size.

Explanation:

The evolution of hominids occurred over a long period of time and included several steps in order for evolution to reach the Homo sapiens which is now known.

For this reason, the statement which best describes the evolution of hominids is that hominids first developed tools, then language and the brain increased in  size.

i would have to say autosomal

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
