user: Answer the following question given this paragraph:   The related field of biochemistry overlaps to some extent with organic chemistry. Biochemistry is the study of the chemistry of living systems. Many biochemical compounds are considered to be organic chemicals. Both of the molecules shown above are biochemical materials in terms of their use in the body, but organic chemicals in terms of their structure and chemical reactivity.   Q: Biochemistry is the study of the chemistry of?   Choices:  - the Earth  - inorganic matter  - abiotic factors  - living systems  A:
living systems

Answer the following question given this paragraph:      Q: Untreated botulism is typically fatal because muscles required for breathing fail to contract when the release of what chemical is blocked?   Choices:  - carbon dioxide  - monoxide  - hydrogen  - acetylcholine  A:
(Answer)
acetylcholine


Ques: Answer the following question given this paragraph:   Potassium is a soft, silvery metal that ignites explosively in water. It easily loses its one valence electron to form positive potassium ions (K + ), which are needed by all living cells. Potassium is so important for plants that it is found in almost all fertilizers, like the one shown here. Potassium is abundant in Earth’s crust in minerals such as feldspar.   Q: Potassium is a soft, silvery metal that ignites explosively in what?   Choices:  - air  - cold  - acid  - water  A:
Ans: water


(Q).
Answer the following question given this paragraph:   23.4 The Stomach The stomach participates in all digestive activities except ingestion and defecation. It vigorously churns food. It secretes gastric juices that break down food and absorbs certain drugs, including aspirin and some alcohol. The stomach begins the digestion of protein and continues the digestion of carbohydrates and fats. It stores food as an acidic liquid called chyme, and releases it gradually into the small intestine through the pyloric sphincter.   Q: What organ participates in all digestive activities except ingestion and defecation?   Choices:  - small intestine  - tongue  - large intestine  - stomach  A:
(A).
stomach


Ques:Answer the following question given this paragraph:   Runner’s Knee Runner’s knee, also known as patellofemoral syndrome, is the most common overuse injury among runners. It is most frequent in adolescents and young adults, and is more common in females. It often results from excessive running, particularly downhill, but may also occur in athletes who do a lot of knee bending, such as jumpers, skiers, cyclists, weight lifters, and soccer players. It is felt as a dull, aching pain around the front of the knee and deep to the patella. The pain may be felt when walking or running, going up or down stairs, kneeling or squatting, or after sitting with the knee bent for an extended period. Patellofemoral syndrome may be initiated by a variety of causes, including individual variations in the shape and movement of the patella, a direct blow to the patella, or flat feet or improper shoes that cause excessive turning in or out of the feet or leg. These factors may cause in an imbalance in the muscle pull that acts on the patella, resulting in an abnormal tracking of the patella that allows it to deviate too far toward the lateral side of the patellar surface on the distal femur. Because the hips are wider than the knee region, the femur has a diagonal orientation within the thigh, in contrast to the vertically oriented tibia of the leg (Figure 8.17). The Q-angle is a measure of how far the femur is angled laterally away from vertical. The Q-angle is normally 10–15 degrees, with females typically having a larger Q-angle due to their wider pelvis. During extension of the knee, the quadriceps femoris muscle pulls the patella both superiorly and laterally, with the lateral pull greater in women due to their large Q-angle. This makes women more vulnerable to developing patellofemoral syndrome than men. Normally, the large lip on the lateral side of the patellar surface of the femur compensates for the lateral pull on the patella, and thus helps to maintain its proper tracking. However, if the pull produced by the medial and lateral sides of the quadriceps femoris muscle is...   Q: What body joint incurs the most common overuse injury among runners and other athletes?   Choices:  - arm  - heel  - ankle  - knee  A:

Ans:knee


Answer the following question given this paragraph:   The digestive system consists of organs that break down food, absorb nutrients, and eliminate waste. The breakdown of food occurs in the process of digestion.   Q: What happens during the process of digestion?   Choices:  - excretion of food  - cell division  - regurgitation  - breakdown of food  A:


assistant: breakdown of food
