Answer 1

Я прикріпила фото з рішенням. Якщо щось не зрозуміло - запитуйте.

Answer 2

I'm sorry, but I am unable to view or analyze images or diagrams. However, I can provide you with some general information about grapevine snails (Cepaea nemoralis) and their characteristics.

Characteristics of Grapevine Snails:

Grapevine snails, also known as Roman snails, are a species of land snail. Here are some general characteristics of grapevine snails:

- Symmetry: Grapevine snails are bilaterally symmetrical, meaning that their left and right sides are mirror images of each other. - Form: The shell of a grapevine snail is spiral-shaped and consists of several whorls. The size and shape of the shell can vary, but it is typically large and can reach up to 4 cm in diameter. - Coloration: The shell of a grapevine snail can have various colors and patterns, including shades of brown, yellow, and white. The coloration can be influenced by factors such as the snail's habitat and diet. - Growth Rings: Grapevine snails have growth rings on their shells, which are often visible as distinct stripes or bands. These rings represent the snail's annual growth and can provide information about its age.

Schematic Drawing of a Grapevine Snail:

Unfortunately, I cannot create or view drawings or diagrams. However, you can find various illustrations and diagrams of grapevine snails by conducting an image search online. These illustrations can help you visualize the different parts of a grapevine snail, such as the apex (top) and aperture (opening) of the shell.

Conclusion:

Based on the information provided, grapevine snails are bilaterally symmetrical, have a spiral-shaped shell with various colors and growth rings, and can reach sizes of up to 4 cm in diameter. Unfortunately, I cannot answer the additional questions about the composition of the snail and how humans use mollusk shells.
