Question

An example of chitinous exoskeleton is

• A. Oriole
• B. Sea stars
• C. Clamp
• D. Honeybee

Answer 1

The correct option is D

Honeybee

The correct option is D.

Explanation for the correct option:

1. Additionally, certain fungi and algae have chitin in their cell walls.
2. It is a nitrogenous polysaccharide in terms of chemistry (a carbohydrate).
3. The Honeybee is an example of an organism with a chitinous exoskeleton.
4. A lot of invertebrate species, including shelled mollusks and other arthropods like insects, spiders, and crustaceans, have exoskeletons.
5. For instance, lobsters have robust outer shell systems that give their body rigidity and shape.
6. Exoskeletons are hard coverings that serve as an animal's external defense against predators.
7. They support the body and act as a little overcoat that prevents the animal from being wet or dehydrated.

Option A:

1. Orioles have a tail that is more golden and a beak and iris that are a paler shade of red.
2. The male has a big carpal patch on the wing, a black eye stripe that extends behind the eye, and wide yellow tips on the secondaries and tertiaries.

Option B:

1. The anatomy of starfish, which have a total of five arms, is very unique.
2. Several spines and pincer-like organs seem to cover the arms (pedicellariae).

Option C:

1. The Polyopisthocotylean monogeneans' primary means of attachment are clamps.
2. Each clamp on the haptor (the posterior attachment organ) of these ectoparasitic worms is attached to the host fish, typically to its gill.

Final answer: An example of the chitinous exoskeleton is honeybees.
