1. if you touch something hot and remove your hand what characteristic would you be displaying?

a. adapting to change b. homeostasis c. responding to stimuli.

1. what do people use to respond to environmental stimuli?

a. their senses b. space c. people do not respond to stimuli
20 what organelle converts food into energy?
a. cell b. autotrophs c mitochondria

Explanation:

1. Heterotrophs cannot produce their own food and rely on other organisms. Animals, fungi, and most protists fit this description.
2. A large brain enables complex problem - solving, walking upright frees the hands, and opposable thumbs allow for grasping and using tools, all of which help humans adapt to various environments.
3. Asexual reproduction involves only one parent. Bacteria reproduce asexually, often through binary fission (a type of asexual reproduction), but the general category is asexual reproduction.
4. Vertebrates reproduce sexually, involving the union of gametes from two parents.
5. Removing your hand when touching something hot is a response to a stimulus (the heat).
6. People use their senses (sight, hearing, touch, taste, smell) to detect and respond to environmental stimuli.
7. Mitochondria are the power - houses of the cell and convert food into energy (ATP).

Answer:

1. A. Heterotrophs
2. C. Large brain and walks upright and has opposable thumbs
3. B. Asexual reproduction
4. C. Sexually
5. C. Responding to stimuli
6. A. Their senses
7. C. Mitochondria
