Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Explanation:
Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.
Answer:
Explanation:
Even if we stopped burning fossil fuels, the Earth would continue warming up for another few decades because of all the heat we've already produced. Global temperatures would climb – finally stabilizing at a level much higher than we've ever known.
Answer and explanation;
The hydrophobic effect is the observed tendency of non-polar substances to aggregate in an aqueous solution and exclude water molecules. Hydrophobic interaction is mostly an entropic effect originating from the disruption of highly dynamic hydrogen bonds between molecules of liquid water by the non-polar solute.
Introduction of such a non-hydrogen bonding surface into water causes disruption of the hydrogen bonding network between water molecules.
Water dissolves molecules (proteins and nucleic acids) that display on their solvent-accessible surfaces groups that can h-bond [hydroxyl, carbonyl, ester groups; they're polar uncharged...also charged groups; protonated amines, carboxylates and phosphate ethers.
Molecules with internal h-bonds dissolve in water, some/all internal h-bonds may be in dynamic exchange with h-bonds in water
.
Polar nature of water contributes to ability to dissolve non-ionic polar organic molecules, such as phenols, esters, amides; have large dipole moments and interaction with water dipole promotes solubility in water.
Explanation:
Heterotroph. 100% correct. Goodluck. glad to help.
