Can you guys please help me? I really need to finish this asap. Thank <3 At one time, scientists classified fungi as non-photosynthetic plants. What is one characteristic of fungi that led scientists to realize that fungi are not plants?

a. Their cells do not contain nuclei.

b. Their cell walls contain chitin.

c. Some live in symbiotic relationships.

d. They reproduce both sexually and asexually.

b

Explanation:

their cell walls contain chitin unlike plant cell walls which contain cell walls

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

atp is used for energy.
