First four are made of rock and rest are made of gases.
Atmospheres of all the planets are made of gases.
B because it’s talking about the tree itself. Saying that it’s plants would divert it to a different plant. The cells of the wood is what makes the tree and is relevant to the question
Answer:
D the train
Explanation:
The train is safe very fast and was the first built
the role of plants in carbon cycle
Explanation:
the amount of CO2 found in the atmosphere varies over the course of a year. much of this variation happens because of the role of plants in carbon cycle...respiration occurs all the time, but domains during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.
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.
