Answer the following question given this paragraph: Most living things use glucose for energy. The process in which glucose is made using light energy is photosynthesis. Water and carbon dioxide are needed for this process, and oxygen is produced as a byproduct. Photosynthetic organisms include plants, algae, and some bacteria. Q: What is the term for the process in which glucose is made using light energy? Choices: - glycolysis - hydration - compress - photosynthesis A:
(Answer)
photosynthesis
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

Answer the following question given this paragraph: How Sciences Interconnect DNA in Forensics and Paternity The genetic material for all living things is a polymer of four different molecules, which are themselves a combination of three subunits. The genetic information, the code for developing an organism, is contained in the specific sequence of the four molecules, similar to the way the letters of the alphabet can be sequenced to form words that convey information. The information in a DNA sequence is used to form two other types of polymers, one of which are proteins. The proteins interact to form a specific type of organism with individual characteristics. A genetic molecule is called DNA, which stands for deoxyribonucleic acid. The four molecules that make up DNA are called nucleotides. Each nucleotide consists of a single- or double-ringed molecule containing nitrogen, carbon, oxygen, and hydrogen called a nitrogenous base. Each base is bonded to a five-carbon sugar called deoxyribose. The sugar is in turn bonded to a phosphate group (PO 4 3) When new DNA is made, a polymerization reaction occurs that binds the phosphate group of one nucleotide to the sugar group of a second nucleotide. The nitrogenous bases of each nucleotide stick out from this sugar-phosphate backbone. DNA is actually formed from two such polymers coiled around each other and held together by hydrogen bonds between the nitrogenous bases. Thus, the two backbones are on the outside of the coiled pair of strands, and the bases are on the inside. The shape of the two strands wound around each other is called a double helix (see Figure 20.18). It probably makes sense that the sequence of nucleotides in the DNA of a cat differs from those of a dog. But it is also true that the sequences of the DNA in the cells of two individual pugs differ. Likewise, the sequences of DNA in you and a sibling differ (unless your sibling is an identical twin), as do those between you and an unrelated individual. However, the DNA sequences of two related individuals are more similar than the sequences of... Q: A genetic molecule is called dna, which stands for this? Choices: - di-nitrous ammonia - dark nitrogen amine - dense ribonucleic acid - deoxyribonucleic acid A:
(A).
deoxyribonucleic acid
Ques:Answer the following question given this paragraph: tiny gap between two adjacent neurons across which electrical messages are carried by chemicals called neurotransmitters. Q: Electrical messages are carried by chemicals called what? Choices: - receptors - amino acids - Biotoxins - neurotransmitters A:

Ans:neurotransmitters
Answer the following question given this paragraph: When plants and other organisms die, decomposers break down their remains. In the process, they release nitrogen in the form of ammonium ions. This process is called ammonification. Nitrifying bacteria change the ammonium ions into nitrites and nitrates. Some of the nitrates are used by plants. The process of converting ammonium ions to nitrites or nitrates is called nitrification. Still other bacteria, called denitrifying bacteria, convert some of the nitrates in soil back into nitrogen gas in a process called denitrification. The process is the opposite of nitrogen fixation. Denitrification returns nitrogen gas back to the atmosphere, where it can continue the nitrogen cycle. Q: What process is the opposite of nitrogen fixation? Choices: - digestion - respiration - percolation - denitrification A:
denitrification
