Much of the human digestive process takes place in the stomach and small intestine. Glands secrete enzymes that break down protein chains by chemical reactions. Two important digestive enzymes for proteins are pepsin and trypsin. The
effect of the pH on the activity of these enzymes can be determined by analyzing the data below. Plot the data from the
data tables on the graph below and then analyze the activity of the two enzymes to answer the questions. Use two
different colors for your lines and provide a key. Make sure that your graph has the axes appropriately labeled and has a
descriptive title.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.

they have identical fossils of organisms that have evolved over time.

both have animal fossils preserved in them due to weathering and erosion.

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.
