Over all, it is a pretty good answer and very complete. I wouldn't say Kudzu "climbs", I suggest just to say it grows up on other plants and trees affecting them negatively by suffocating them.
Maybe you could explain a little bit more about the characteristics of the plant.
It is excellent how you say it is an agressive and competitor but I wouldn't compare it with a predator, maybe more with a parasite.
I think option C is correct because snakes r not omnivores they eat insects not plants so option D and A are wrong
In option B eagle is carnivore
Fish can be omnivores, but some species are carnivores or herbivores. In general, a fish's diet is determined mostly by its habitat and what food is available. Most species have a preferred diet but will eat outside of that if necessary for survival.
Bear can also b omnivore
The neurotransmitter that is responsible for the voluntary movement of muscles in the arm is ACETYLCHOLINE.
Acetylcholine is the neurotransmitter that act at neuromuscular junctions, that is, it is released by the nervous system to activate muscle movement. Muscular contraction is usually initiated by the release of acetylcholine by the nervous system.
