Answer:
A) more snow falling than snow melting
Explanation:
"Three conditions are necessary to form a glacier: (1) Cold local climate (polar latitudes or high elevation). (2) snow must be abundant; more snow must fall than melts, and (3) snow must not be removed by avalanches or wind"
Which of the mass movements requires water to be present?
mudflows
creep
landslides
slump
What does the texture, or particle size, of soil determine?
how much litter will form in the soil
the fertility of the soil that is formed
how much air and water the soil can hold
whether the soil formed is topsoil or subsoil
Answer:
Texture indicates the relative content of particles of various sizes, such as sand, silt and clay in the soil. Texture influences the ease with which soil can be worked, the amount of water and air it holds, and the rate at which water can enter and move through soil.

Predict what will happen to the concentration of pyruvate, NADH, and H+ when ATP synthase is stopped by oligomycin
The concentration of pyruvate and NADH does not no change, however the concentration of H+ increases.
Oligomycin is a toxic substance to humans, produced by bacteria of the Streptomyces type. It acts by blocking the proton channel in a region of the ATP synthase enzyme, inhibiting oxidative phosphorylation. Thus, the electron transport chain is slowed but not completely stopped.
Cellular respiration consists of a metabolic pathway that breaks down the glucose molecule to produce energy in the form of ATP. Stages of cellular respiration are:
GlycolysisPyruvate oxidationKrebs cycle or the citric acid cycleOxidative phosphorylationGlycolysis consists of the breakdown of glucose to form two pyruvate molecules, where energy is produced in the form of ATP and NADH. Then, pyruvate oxidation occurs, catalyzed by an enzyme called pyruvate dehydrogenase in the mitochondrial matrix. Next, is the Krebs cycle where energy is produced in the form of ATP and other biosynthetic reactions also occur where the intermediates produced are required to make other molecules, such as amino acids, nucleotide bases and cholesterol. Finally, oxidative phosphorylation takes place as a metabolic process that uses energy released by the oxidation of nutrients to produce ATP. It consists of two stages: in the first one, free energy generated by redox chemical reactions in various multiprotein complexes (electron transport chain) and produces an electrochemical gradient of protons (H+) across an associated membrane in a process called chemiosmosis. The respiratory chain consists of three main protein complexes (complex I, III, IV), and several "auxiliary" complexes, utilizing a variety of electron donors and acceptors. The three complexes associate in supercomplexes to channel electron transport molecules, coenzyme Q and cytochrome c, making the process more efficient. So, the proton gradient produced by proton pumping is used to make ATP molecules. Protons move through the ATP synthase down their concentration gradient into the matrix catalyzing the conversion of ADP to ATP.
Then, using oligocycin there will be no change in the concentration of pyruvate since the synthesis of it (from the breakdown of glucose) does not depend upon an ATP synthase. Also, there is no change in the concentration of NADH because it is oxidized and reduced via redox reactions which also does not depend on the enzyme. At last, there is an increase in the concentration of H+ (protons) because its gradient wont be use by the ATP synthase to make ATP molecules.
