1. the fossil shown in this photo is of a basilosaurus. its skeletal features suggest that it spent its entire life swimming in the ocean. look at the environment the fossil was found in. consider that basilosaurus lived in the ocean. how has the environment of this location changed since basilosaurus lived?

The environment changed drastically probably due to tectonic plates shifting and either causing this part of land to move to a higher altitude or blocking the water from being in this now deserted place. At some point it seemed to be a river shown in the picture of the rock on the top right corner, as the rock looks a bit corroded it seems that the ocean slowly disappeared.

Explanation:

i had to do this to soo hope this helps

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this
