Would scientists succeed in stopping an asteroid from wiping out the human race from existing as it did to the dinosaurs who were very strong and lived for millions of years. Is it that scientists cannot stop asteroids from smashing on our planet because of their chaotic orbit or because nobody is ready to invest on that subject?

What is acetylcholine? Also tell me its effect on the plasma membrance of a muscle cell.

If the water cells inside and outside a cell suddenly become hydrophobic, would the transport of materials into and out of the cells be affected? and how is it affected?

If he had not pulled the dagger out of his body, could he have survived or would the venom have killed him anyway?
Did the serrated edges of the dagger kill him as it exited his heart, or did the venom?
