weathering
Weathering is caused by precipitation reacting
with minerals in the rock.
Weatherira is caused by freezing and thawing
of water.
Weathering creates new substances, such as
clay and salts.
Weathering is caused by the movement of
agents such as glaciers and wind. It is
accelerated by increases in velocity
Weathering is caused by processes such as
corrosion, hydrolysis, and dissolution. It is
accelerated by increases in temperature.

Mouse liver cells were homogenized and the homogenate subjected to equilibrium density-gradient centrifugation with sucrose gradients. fractions obtained from these gradients were assayed for marker molecules (i.e., molecules that are limited to specific organelles). the results of these assays are shown in the figure. the marker molecules have the following functions: cytochrome oxidase is an enzyme involved in the process by which atp is formed in the complete aerobic degradation of glucose or fatty acids; ribosomal rna forms part of the protein-synthesizing ribosomes; catalase catalyzes decomposition of hydrogen peroxide; acid phosphatase hydrolysis monophosphoric esters at acid ph; cytidylyltransferase is involved in phospholipid biosynthesis; and amino acid permease aids in transport of amino acids across membranes. a) name the marker molecule and give the number of the fraction that is most enriched for each of the following cell components: lysosomes; peroxisomes; mitochondria; plasma membrane; rough endoplasmic reticulum; smooth endoplasmic reticulum.

Which of the following is the most likely outcome of global warming
