The Asian long-horned beetle can infect a variety of tress such as maple trees and elm trees. These beetles eat the inside infected tree and destroy the pathways that water and nutrients travel through to get from the roots to the rest of the tree. This
results in the tree becoming sick and eventually dying.
A cargo ship carrying Asian long-horned beetles introduces the species into a region where the beetles were not previously present.
This region has a diverse population of maple and elm trees. How will humans in the area likely be impacted?
OA. The maple syrup industry will be negatively impacted due to a decrease in the maple population.
OB. The housing industry will be negatively impacted due to an increase in lumber costs.
OC. The lumber industry will be negatively impacted due to a decrease in available resources.
OD. all of these

If you add 10ml of hot water to 10ml of cold water and the change in tempature 8°c calculate how much energy is gained by the cold water

A3.37-mg sample of protein was chemically digested to convert its nitrogen into ammonia and then diluted to 100.0 ml. then 10.0 ml of this solution was placed in a 50-ml volumetric flask and treated with 5 ml of phenol solution plus 2 ml of sodium hypochlorite solution. the sample was diluted to 50.0 ml, and the absorbance at 625 nm was measured in a 1.00-cm cuvette and found to be 0.486. for reference, a standard solution was prepared from 10.0 mg of nh4cl (molar mass = 53.49 grams/mole) dissolved in 1.00 l of water. then 10.0 ml of this standard was placed in a 50-ml volumetric flask, treated in the same manner as the unknown, and the absorbance found to be 0.323. finally, a reagent blank was prepared using distilled water in place of unknown, it was treated in the same manner as the unknown, and the absorbance found to be 0.076. calculate the weight percent of nitrogen in the protein.

What effect would average population growth have on land usage? a. urban use of land would rise to more than 30 percent of available land. b. industrial use of land would rise to more than 30 percent of available land. c. the percentage of available land used as cropland would stay the same. d. cropland would fall to about 10 percent of available land.
