Question

20 multiple choice 2 points a bacterium divides into two bacteria which are identical to, but smaller than the original bacterium. this is an example of which characteristic of life? adaptation growth homeostasis reproduction 21 multiple choice 2 points which of the following is not a stimulus that a living thing might sense and respond to? hunger sound dna light

Explanation:

• Question 20: Reproduction is the process by which organisms produce offspring. In this case, the bacterium is producing new bacteria (offspring) through division. Adaptation is about adjusting to the environment, growth would involve the bacterium getting larger (not splitting into two), and homeostasis is maintaining a stable internal environment.
• Question 21: Hunger (internal physiological signal), sound (external sensory input), and light (external sensory input) are all stimuli that living things can sense and respond to. DNA is the genetic material of an organism and not a stimulus that an organism senses and responds to in the way the question is asking.

Answer:

1. Reproduction
2. DNA
