Giải bởi Vietjack
Theo đoạn văn, tại sao kiến sử dụng các hợp chất khác nhau làm pheromone?
A. Để giảm độ nhạy cảm của chúng với một số hóa chất
B. Để thu hút các loại kiến khác nhau
C. Để bảo vệ dấu vết của chúng khỏi các loài khác
D. Để cho biết thực phẩm cách bao xa
Đáp án C
Thông tin ở đoạn sau: “Unlike some other messages, such as the one arising from a dead ant, a food trail has to be kept secret from members of other species. It is not surprising then that ant species use a wide variety of compounds as trail pheromones.” (Không giống như những lời nhắn khác, ví dụ như cái phát ra từ một con kiến chết, một dấu vết thức ăn phải được giữ bí mật với các thành viên của các loài khác. Thật không ngạc nhieen khi các loài kiến sử dụng nhiều nhiều hợp chất khác nhau làm chất chi phối dấu vết.)
