Answer 1

В)-стрекательные клетки производные эктодермы.

Answer 2

The function that is NOT characteristic of the intestinal cavity with its surrounding endoderm is A. Providing the body with oxygen.

The intestinal cavity and its surrounding endoderm primarily serve functions related to digestion and absorption of nutrients. Let's go through each option to determine which one is not characteristic of the intestinal cavity:

A. Providing the body with oxygen: The primary organ responsible for providing oxygen to the body is the lungs, not the intestines. The intestines are not involved in the exchange of oxygen and carbon dioxide.

B. Excretion of waste products: The intestines do play a role in the excretion of waste products, specifically in the form of feces. After digestion and absorption of nutrients, waste products are eliminated from the body through the intestines.

C. Placement of protective secretory cells: The intestinal lining contains various types of cells, including goblet cells, which secrete mucus to protect the intestinal wall from mechanical damage and provide lubrication for the passage of food.

D. Capture and digestion of food particles: The intestines are responsible for the capture and digestion of food particles. Once food enters the intestines, it is broken down further by enzymes and absorbed into the bloodstream.

Based on the above analysis, the function that is NOT characteristic of the intestinal cavity with its surrounding endoderm is A. Providing the body with oxygen.
