Question

Обьясните, почему панцирь членистоногих является наружным скелетом​

Answer 1

Объяснение:

Панцирь членистоногих является наружный скелетом из-за того, что изнутри к нему прикрепляются мышцы.

Однако у панциря имеется недостаток. Он не может расти вместе с телом, из-за чего происходит линька.

Answer 2

The Exoskeleton of Arthropods

The exoskeleton of arthropods, including insects, crustaceans, and other arthropods, is an external skeleton that serves several important functions. This exoskeleton is made of a tough, rigid material called chitin, which provides support and protection for the animal's body.

1. Protection: One of the main reasons why arthropods have an exoskeleton is for protection. The hard outer shell helps shield the soft internal organs from physical damage and predators.

2. Structural Support: The exoskeleton provides structural support for the arthropod's body. It acts as a framework, giving the animal's body shape and allowing it to maintain its form.

3. Attachment for Muscles: The exoskeleton serves as an attachment point for the arthropod's muscles. The muscles are attached to the inner surface of the exoskeleton, allowing the animal to move its limbs and perform various activities.

4. Prevents Desiccation: The exoskeleton also helps prevent desiccation, or excessive water loss, in arthropods. The chitinous exoskeleton acts as a barrier, reducing water loss through evaporation and helping the animal retain moisture.

5. Sensory Functions: The exoskeleton of arthropods also plays a role in sensory functions. It contains specialized structures, such as hairs and bristles, that can detect touch, vibrations, and other environmental stimuli.

6. Growth and Molting: Arthropods have a unique growth process called molting. As they grow, they shed their old exoskeleton and replace it with a new, larger one. This allows the arthropod to accommodate its increasing body size. During molting, the arthropod secretes a new exoskeleton underneath the old one, and then sheds the old exoskeleton to reveal the new one.

In summary, the exoskeleton of arthropods serves multiple functions, including protection, structural support, muscle attachment, prevention of desiccation, sensory functions, and facilitating growth through molting. It is a remarkable adaptation that has contributed to the success and diversity of arthropods in various ecosystems
