The sugar pill serves as a control.
The control in experiments is a sample that remains the same throughout the experiment and it is used to compare the results of the main experiment to. It serves to guarantee that changes noted in the experiment are from the variables introduced and not something else.
Answer:
The shape in V of the vomerine teeth is useful to hook the prey and hold it until the frog can swallow it.
Explanation:
In frogs, we can distinguish maxillary teeth, premaxillary teeth, and Vomerine teeth.
Vomerine teeth are projections of the vomer bone, located in the anterior part of the paladar and between the internal nares.
Vomerine teeth are specialized structures that help frogs catch and hold their prey. They are not involved in chewing or killing (frogs swallow the entire prey alive), just holding the creature before swallowing it.
These projections are covered by soft tissue. When the frog catches the prey, presses the tongue against the roof of your mouth. The vomerine teeth hook the prey and prevent it from slipping or wandering away.
The shape in V of the vomerine teeth is useful to hook the prey and hold it until the frog can swallow it.
