D- as diffusion of water through a selectively permeable membrane
Answer:
surface tension
hope this helps, plz mark me as brainliest.
Precipitation, because when water evaporates it then condenses into clouds and releases precipitation(Liquid water) back into the cycle to balance it.
Answer:
Bond energy is the amount of energy that breaks a bond. Energy is added to break bonds and energy is also released when bonds form. ... In an exothermic reaction, the products have (more or less) energy than the reactants.
Explanation:
The synthesis of fatty acids starts with a preparratory phase in which acetyl CoA is translocated from mitochondria to the cytosol. However, it cannot pass through the membrane, so it is translocated as citrate that is cleaved to acetyl CoA and oxaloacetate.
In the cytosol, acetyl CoA is transformed to malonyl-CoA, that is, a three carbon compound. Fatty acid synthesis starts with the transfer of the acetyl group from acetyl-CoA to fatty acid synthase.
Two-carbon groups supplied by malonyl-CoA, are supplemented to the developing acyl chain in a series of steps involving condensation, reduction, and dehydration reactions. Elongation of the fatty acid chain ceases at 16 carbon atoms, after 7 cycles, as the free fatty acid is discharged.
