Ques: Answer the following question given this paragraph: The photos in Figure below show how farming practices can increase soil erosion. Plant roots penetrate the soil and keep it from eroding. Plowing turns over bare soil and cuts through plant roots. Bare soil is exposed to wind and water. In the past, farmers always plowed fields before planting. Some farmers now use no-till farming, which does not disturb the soil as much. Q: No-till farming is one effort to combat what, caused by typical farming practices? Choices: - habitat destruction - drought - pollution - soil erosion A:
Ans: soil erosion

Ques: Answer the following question given this paragraph: Liverworts, hornworts, and mosses are modern bryophytes. Liverworts are named for the liver-shaped leaves of some species. Hornworts are named for their horn-like sporophytes. Q: Which type of bryophytes are named for their horn-like sporophytes? Choices: - arthropods - flatworms - tapeworms - hornworts A:
Ans: hornworts

Ques: Answer the following question given this paragraph: The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at the cathode. The minus sign is necessary because oxidation is the reverse of reduction. Ecell = Ecathode Eanode +0.34 V = E 2+ EH + /H = E 2+ 0 = E Cu. Q: The standard reduction potential can be determined by subtracting the standard reduction potential for the reaction occurring at the anode from the standard reduction potential for the reaction occurring at this? Choices: - Spinner - plasma - electrode - cathode A:
Ans: cathode

Ques: Answer the following question given this paragraph: The internal carotid artery enters the cranium through the carotid canal in the temporal bone. A second set of vessels that supply the CNS are the vertebral arteries, which are protected as they pass through the neck region by the transverse foramina of the cervical vertebrae. The vertebral arteries enter the cranium through the foramen magnum of the occipital bone. Branches off the left and right vertebral arteries merge into the anterior spinal artery supplying the anterior aspect of the spinal cord, found along the anterior median fissure. The two vertebral arteries then merge into the basilar artery, which gives rise to branches to the brain stem and cerebellum. The left and right internal carotid arteries and branches of the basilar artery all become the circle of Willis, a confluence of arteries that can maintain perfusion of the brain even if narrowing or a blockage limits flow through one part (Figure 13.15). Q: Which artery enters the cranium through the carotid canal in the temporal bone? Choices: - atrial artery - external carotid - venal artery - internal carotid artery A:
Ans:
internal carotid artery
