Question

Some organisms, such as tapeworms, are noted for tolerating a wide pH range. What is this range?

Options

• pH 2 to 5

• pH 4 to 11

• pH 6 to 9

• pH 1 to 14

Answer 1

Tapeworms tolerate a wide pH range of pH 4 to 11. While most organisms are restricted to narrow pH ranges, some parasitic organisms like tapeworms have evolved to survive in the highly varied pH conditions of different host environments.
