Question

Indicate whether each of the following descriptions applies to cilia (C), flagella (F), or both (B). Your answer would be a four-letter string composed of letters C, F, and B only, e.g. CCFB.

(A) They are short and present at high numbers per cell.
(B) They have a whiplike motion that resembles breaststroke in swimming.
(C) They are based on the axoneme structure.
(D) They are found in the epithelial cells of the human respiratory tract.

Answer 1

The descriptions (A) applies to Cilia (C); descriptions (B) and (C) apply to Both (B) cilia and flagella; and description (D) applies to Cilia (C), resulting in the answer code CBBC.

Step-by-step explanation:

To determine whether the descriptions apply to cilia (C), flagella (F), or both (B), we evaluate each statement:

• (A) They are short and present at high numbers per cell. - Cilia (C)
• (B) They have a whiplike motion that resembles breaststroke in swimming. - Both (B)
• (C) They are based on the axoneme structure. - Both (B)
• (D) They are found in the epithelial cells of the human respiratory tract. - Cilia (C)

Therefore, the four-letter string composed of letters C, F, and B only that represents the correct answer is CBBC.
