Question
Chapter 25, Problem 2CONQ
Summary Introduction
To review:
Whether the given statements regarding body axes in mice are true or false.
A. Head is present posterior to the tail, along the anteroposterior axis.
B. Vertebrae of the back are dorsal to the stomach, along the dorsoventral axis.
C. Feet are dorsal to the hips, along the dorsoventral axis.
D. Feet on hind legs are distal to the upper parts of hind legs, along the proximodistal axis.
Introduction:
The adult body of a fruit fly is divided into two axes. These two axes are; the dorsoventral axis and the anteroposterior axis. Proximodistal axis is used to assign the limbs of an organism. Anteroposterior axis extends from the anterior to the posterior part of the body of an organism while, the dorsoventral axis extends from the dorsal to the ventral part of the body.

Find the dental formula and enter it in the following format:
I3/3 C1/1 P4/4 M2/3 = 42 (this is not the correct number, just the correct format)
Please be aware: the upper jaw is intact (all teeth are present). The bottom jaw/mandible is not intact. The front teeth should include 6 total rectangular teeth (3 on each side) and 2 total large triangular teeth (1 on each side).
