Which of the following are photosynthesis autotrophs?

answer:

algae, plants and some bacteria

explanation:

photosynthetic autotrophs are organisms that utilize light or energy from the sun  to synthesize organic compounds or food. examples of photosynthetic autotrophs are algae, plants and cyanobacteria. protists do not have chloroplasts or any membrane bound organelles. arthropods do not have chloroplasts since they dont contain plant cells.

answer:

i'm not able to see all the options. but photosynthetic autographs include plant, some bacteria and blue-green algae. it would have been if i knew all the options. if this answer would not suffice, care to let me know of the options.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
