Answer:
Answer 4: Plants do respond differently to different colors of light being shone on them, because chlorophyll reflects green light and absorbs blue and red (therefore, blue and red are useful for photosynthesis, but green isn't).
Answer:
Plants can't use N2 as is so the first option is wrong. They do have relationships with bacteria that live in nodules of the root and convert the nitrogen into ammonia, a usable form for the plants. So the second option is correct. There are bacteria living in the soil as well that convert nitrogen to ammonia so technically option 3 is also correct. Again, nitrogen if present in water would be in the form N2 which is not usable by plants so 4 is wrong.
These are correct:
use bacteria to convert nitrogen to usable form
In obtain usable nitrogen compounds from the soil
A valence electron is a negatively charged particle, located in the outermost shell of an atom, that can be transferred to or shared with another atom.
Option A.
