This plant needs to grow high up in the canopy of the rainforest. it needs support as it moves up the stems and branches of larger trees. the tendrils here know when to cling to their support. this response by the climbing plant is called a) gravitropism. b) hydrotropism. c) phototropism. d) thigmotropism. biology katieb

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

idk what the options are but

these is a strong electrostatic attraction between the ions hence a lot of energy is needed to overcome this attraction

this is why the boiling points are so high
