Umnica [9.8K]

Answer:

The <u>shape in V</u> of the vomerine teeth is useful to <u>hook the prey and hold i</u>t 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<u> shape in V</u> of the vomerine teeth is useful <u>to hook the prey and hold it </u>until the frog can swallow it.

In the given experiment, the potted tomato plants were treated with different amounts of fertilizer to observe the effect of the amount of fertilizer on the plant yield. Therefore, the amount of fertilizer is an independent variable here. Since the effect of change in the amount of fertilizer was observed in terms of plant yield, the "plant yield" is a dependent variable in the experiment.
