Passive transport is a movement ofbiochemicals and other atomic or molecularsubstances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy. The rate of passive transport depends on thepermeability of the cell membrane, which, in turn, depends on the organization and characteristics of the membrane lipids andproteins. The four main kinds of passive transport are simple diffusion, facilitated diffusion, filtration and osmosis.
Answer:
it is true. Watersheds can be as small as a footprint or large enough to encompass all the land
Answer: radiation i think
The
correct answer is mutualistic bacteria in the hindgut of the termite digest the
cellulose into sugars.
<span>
Termites
depend upon the whole complex of microbes in their hindgut. Microbes inside the
termites help the breakage of the complex sugars like a cellulose into short-chain
fatty acids.</span>
The right answer is spongy bone (cancellous bone).
In otosclerosis, the new bone blocks the movement of the stirrup, causing transmission hypoacusia. Otosclerosis can also cause perceptive deafness, especially when otosclerotic bone foci are close to scala media. Half of all cases are hereditary. The measles virus may play a role in triggering a genetic predisposition to otosclerosis.
