A. objects made of crystals minerals water and air
Process of elimination-
there isn’t organic matter in rocks so D is out
they are made of minerals so B is out
some types of rock (pumice) have air bubbles in them so A is more likely than C
Answer: Electromagnetic waves
Explanation: The main property of the waves is the way how they propagate or travel in medium The waves which can travel without a medium is said to travel in vacuum or air.
Answer:
Dissociation of actin subunits occurs.
Explanation:
When we add phalloidin to a solution containing G-actin, the phalloidin binds to actin filaments more tightly as compared to actin monomers which leads to a decrease in the constant rate of dissociation of actin subunits from the ends of the filament. This dissociation stabilizes the actin filaments through the prevention of filament depolymerization. So we can conclude that addition of phalloidin to actin leads to stabilizing of actin filaments.
Answer: The pH scale measures whether there is more hydroxide or hydronium in a solution.
Is important because it tells you how basic or acidic the solution is.
