Answer:
Turtle
Explanation:
I would think a turtle because of its shell and bones. The shell or bones could leave an imprint in mud that could turn into a fossil or the bones/shell itself could become a fossil.

2) the middle layer that is myometrium
3) the inner layer which is known as endometrium.
The middle layer is responsible for the uterine contraction and as a result, one have menstrual cramps.
Answer:
they carry out experiments to understand it
Explanation:
Scientists raise hypotheses which are tested by experiments made under controlled conditions in order to explain a particular topic. When a hypothesis is confirmed by the experimental data, the evidence obtained from this experiment provides the basis to increase the scientific knowledge about a particular issue. In consequence, experimentation can be considered as a critical step in the scientific method and research aims to advance knowledge of a particular phenomenon by confirming a hypothesis, which must be testable (i.e. verifiable as a result of further experimentations).
