It is rare for soft tissue to become a fossil because the soft parts can be eaten by other animals. Hope this helps!
Answer:
Pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
Explanation:
I just took the QUIZ the answer to this question is
The phenotype frequency does not change.
Rotational movements need the most thoracic mobility. This is because a rotational movement (such as twisting) because the movements are more three dimensional, and this is where the most can go wrong. For example, if you were holding a 35lb child and simply bent forward to put him/her down, this is less likely to cause injury than if you were to twist your torso to the right and put the child down. There is a lot more spinal stability and mobility needed for the second motion than the first.
