“Anaerobic respiration is only used when aerobic respiration is not an option.” (1 point)

This is not correct, because some organisms are more efficient with anaerobic respiration, producing more ATP.

This is correct, because aerobic is more efficient than anaerobic, making it preferable.

This is not correct, because some organisms cannot perform aerobic respiration, so anaerobic is the only option.

This is correct, because animals need aerobic respiration to live and cannot survive on anaerobic.

well, you see. the answer to your question is quite simple. the thing that is big, powerful, and over 9,000 is your mom.

what subject is this

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
