6 If a population is experiencing a decrease in size, how
do the birth and death rates compare?

If a population is decreasing, there would be less births than deaths. if a population increases, then there would be more births than deaths. it all revolves around those two statements, whether it’s decreasing or increasing. hope this helped ;)

Ifound this on google “according to the findings, a foramen magnum positioned toward the base of the skull is found not only in humans, but in other habitually bipedal mammals as well.” i hope this you for what your looking for

The answer is observations and interpreting.
