4.
What is the function of the nictitating membrane?
Correct Answer
B. It guards the frog's eyes.
Explanation
The correct answer is "It guards the frog's eyes." The nictitating membrane is a transparent third eyelid found in frogs and some other animals. It serves to protect the frog's eyes by acting as a barrier against debris, water, and other potential hazards. It can be quickly drawn across the eye to provide additional protection while still allowing the frog to see. This membrane is particularly useful for frogs that live in aquatic environments or have to navigate through dense vegetation.
5.

6.
Name the organ which helps the frog to breathe air.
Correct Answer
A. Nostrils
Explanation
The nostrils of a frog are the organs that help it to breathe air. Frogs have two nostrils located on the top of their snout, which allow them to inhale and exhale air. When a frog is on land, it breathes through its nostrils, taking in oxygen and releasing carbon dioxide. This is essential for the frog's survival as it allows it to exchange gases with the environment and obtain the oxygen it needs to live.
7.
Which body organ behaves like a fly-catching device and allows the frog to reach great lengths?
Correct Answer
B. Tongue
Explanation
The frog's tongue behaves like a fly-catching device and allows the frog to reach great lengths. The tongue is designed to be sticky and can be rapidly extended out of the frog's mouth to catch prey. This unique adaptation enables the frog to quickly snatch insects and other small prey from a distance, making it an effective hunting tool.
8.

Correct Answer
A. Teeth found on the upper jaw.
Explanation
The maxillary teeth refer to the teeth found on the upper jaw. This is in contrast to the mandibular teeth, which are found on the lower jaw. The maxillary teeth play a crucial role in biting, chewing, and breaking down food before it is swallowed. They are also important for speech and maintaining the structure of the face.
9.
The tube leading from the throat to the inside of the tympanic membrane of the ear is called _____________.
Correct Answer
A. Eustachian tubes
Explanation
The tube leading from the throat to the inside of the tympanic membrane of the ear is called the Eustachian tubes. These tubes help equalize the pressure between the middle ear and the atmosphere, allowing the eardrum to vibrate properly. They also help drain fluids from the middle ear to prevent infections. The lymph node is not related to the ear, and the gullet is the passage between the mouth and the stomach, so they are not the correct answers.
