What tubes?

help pls

The main purpose of these tubes is to carry nutrients and wastes. To arrive at this answer, we can analyze each option:

A. Making flowers for reproduction: This option refers to the function of the reproductive organs in flowers, which are not tubes. This option is incorrect.

B. Creating speech: Speech production involves the coordination of various structures in the oral and respiratory systems, but the term "tubes" does not specifically relate to this process. This option is incorrect.

C. Carrying nutrients and wastes: This option aligns with the main purpose of tubes in living organisms, such as blood vessels transporting nutrients and waste products, as well as the digestive system's intestine and urinary system's ureters carrying waste materials. This option is correct.

D. Taking in and responding to signals from the environment: This option does not relate directly to the function of tubes; it seems to describe the functions of sensory organs and the nervous system. This option is incorrect.

Therefore, the correct answer is C. Carrying nutrients and wastes.
