NO.
aquaporins are pores and are meant for facilitated diffusion.
Yes
mitochonria
Osmosis is the membrane activity that does not require the expenditure of energy by the cell. It does not require any input of energy.
depends on your definition of activity and what scope you are looking at things, but yes, there is energy put into the process at some point. just remember that diffusion and other similar phenomenon don't require energy usage on the part of the organism
No, it does not require energy use from the cell.
Water flowing downhill does not require energy, only the force of gravity.
All biological activities require energy?
Any activity, or process, requires energy.
breathing blood pumping brain activity stomach activity kidney and liver activity
An ion channel is a passive transport and does not require energy for it to occur. An ion pump, meanwhile, is an active transport and requires an input of energy for it begin.
mitochonria
Osmosis is the membrane activity that does not require the expenditure of energy by the cell. It does not require any input of energy.
Physical activity gives you a way to channel the negative energy and frustration you feel out of your body. It is a healthy way to release your emotions and gain a sense of control that helps you deal with stress.
ATP is the energy currency of life that provide energy to the biological reactions. Kinases that phosphorylate their substrates require ATP. Membrane channel proteins that conduct active transport needs ATP. These proteins utilize the energy found in ATP, by breaking them in to ADP plus inorganic phosphate.
no it does not require energy.

endothermic reactions require energy
All of your cells require energy. Without energy you wouldn't be alive.
