Answer 1

The mammal represented by the dental formula 2/1, 0/0, 3/2, 3/3 lacks canine teeth, as indicated by the 0/0 in the formula.

Step-by-step explanation:

The mammal skull found in the yard, based on the dental formula provided, lacks canines. The dental formula given is 2/1, 0/0, 3/2, 3/3, which represents the number of incisors, canines, premolars, and molars respectively. When looking at the formula, we notice that the count for canines is 0/0, indicating that there are no canines present among the other types of teeth, which include incisors, premolars, and molars.
