Answer the following question given this paragraph: Cecum The first part of the large intestine is the cecum, a sac-like structure that is suspended inferior to the ileocecal valve. It is about 6 cm (2.4 in) long, receives the contents of the ileum, and continues the absorption of water and salts. The appendix (or vermiform appendix) is a winding tube that attaches to the cecum. Although the 7.6-cm (3-in) long appendix contains lymphoid tissue, suggesting an immunologic function, this organ is generally considered vestigial. However, at least one recent report postulates a survival advantage conferred by the appendix: In diarrheal illness, the appendix may serve as a bacterial reservoir to repopulate the enteric bacteria for those surviving the initial phases of the illness. Moreover, its twisted anatomy provides a haven for the accumulation and multiplication of enteric bacteria. The mesoappendix, the mesentery of the appendix, tethers it to the mesentery of the ileum. Q: What is the first part of the large intestine called? Choices: - duodenum - colon - jejunum - cecum A:
cecum

Answer the following question given this paragraph: Scientists think that glycolysis evolved before the other stages of cellular respiration. This is because the other stages need oxygen, whereas glycolysis does not, and there was no oxygen in Earth's atmosphere when life first evolved about 3.5 to 4 billion years ago. Cellular respiration that proceeds without oxygen is called anaerobic respiration . Q: What do you call cellular respiration that does not need oxygen to proceed? Choices: - aerobic respiration - malolactic respiration - cellular breathing - anaerobic respiration A:
(Answer)
anaerobic respiration
Ques: Answer the following question given this paragraph: A: Any element in group 1 has just one valence electron. Examples include hydrogen (H), lithium (Li), and sodium (Na). Any element in group 18 has eight valence electrons (except for helium, which has a total of just two electrons). Examples include neon (Ne), argon (Ar), and krypton (Kr). Oxygen, like all the other elements in group 16, has six valence electrons. Q: How many valence electrons does a sodium atom have ? Choices: - three - six - two - one A:
Ans: one
(Q).
Answer the following question given this paragraph: Insulin was the first human protein to be produced in this way. Insulin helps cells take up glucose from the blood. People with type 1 diabetes have a mutation in the gene that normally codes for insulin. Without insulin, their blood glucose rises to harmfully high levels. At present, the only treatment for type 1 diabetes is the injection of insulin from outside sources. Until recently, there was no known way to make insulin outside the human body. The problem was solved by gene cloning. The human insulin gene was cloned and used to transform bacterial cells, which could then produce large quantities of human insulin. Q: What helps cells take up glucose from the blood? Choices: - oxygen - hemoglobin - estrogen - insulin A:
(A).
insulin
Ques:Answer the following question given this paragraph: Fertilizer in runoff leads to algal blooms and dead zones in bodies of water. This type of pollution is called nonpoint-source pollution. Point-source pollution includes waste water from factories and sewage treatment plants. Hot water discharge causes thermal pollution. Q: What causes eutrophication to occur? Choices: - excess of decreased and other nutrients - excess of carbonate and other nutrients - excess of increased and other nutrients - excess of fertilizers and other nutrients A:

Ans:excess of fertilizers and other nutrients
Question: Answer the following question given this paragraph: The boy in Figure below is working out on a hot day. He's losing a lot of water in sweat. To maintain homeostasis, his body can balance the water lost in sweat by excreting less water in urine. The amount of water lost in urine is controlled by the kidneys. The kidneys are organs of excretion. Q: Which organ in the body controls the amount of water loss in urine in response to maintaining homeostasis? Choices: - lungs - liver - spleen - kidneys A:
Answer:
kidneys
