I think it would be d part

Answer 2

Answer: The correct answer is D) 0.5 to 1.5 micrometer inti diameter.

Explanation: Bacterias are very small in size that is why they are visible under the microscope and cannot be seen by naked eyes . Due to their smaller size they are able to exploit and thrive in various micro-environments . Bacteria can continue to rely on hosts for the nutrition , they can live and survive in environments that contain a low concentration of nutrients . They have a high surface area to volume ratio that allows them to take up as many nutrients as possible and in that process they are able to continue growing and reproducing at a steady rate . The smallest bacteria are micro organisms also known as nano bacterium .These bacterias vary in shape , size and arrangement . They are classified based on their shape . For example : cocci , bacillus bacteria ( rod - shaped ) , spirochete , haloarcula , star-shaped bacteria , rectangular bacteria , stalked bacteria .
