What set of characteristics do living organisms such as birds, trees, and bacteria have that distinguish them from nonliving thi
Sergio [31]
The 7 (sometimes 8) characteristics of life are:
1. living things are composed of cells
2. living things have different levels of organization
3. living things metabolize (i.e. use energy)
4. living things respond to their environment
5. living things grow
6. living things reproduce
7. living things adapt to their environment
(some sources include) 8. living things have genetic material

Viruses do not metabolize, they do not grow, they do not adapt to their environment, and they cannot reproduce independently; viruses require host cells to reproduce and perform the other functions that give them the appearance of aliveness.

HELP EXTRA POITNS BRAINLIEST !!!
patriot [66]
I think the second option is the best (by making the ramps height and length equal) because the first option will require more pushing, the third option will only make the ramp lighter which could cause it to not stay in place, the last option would make it harder to push the boxes up because the rubber will make it harder to slide the boxes up. I hope this helps:)
