Answer the following question given this paragraph: Blood Supply The major function of the lungs is to perform gas exchange, which requires blood from the pulmonary circulation. This blood supply contains deoxygenated blood and travels to the lungs where erythrocytes, also known as red blood cells, pick up oxygen to be transported to tissues throughout the body. The pulmonary artery is an artery that arises from the pulmonary trunk and carries deoxygenated, arterial blood to the alveoli. The pulmonary artery branches multiple times as it follows the bronchi, and each branch becomes progressively smaller in diameter. One arteriole and an accompanying venule supply and drain one pulmonary lobule. As they near the alveoli, the pulmonary arteries become the pulmonary capillary network. The pulmonary capillary network consists of tiny vessels with very thin walls that lack smooth muscle fibers. The capillaries branch and follow the bronchioles and structure of the alveoli. It is at this point that the capillary wall meets the alveolar wall, creating the respiratory membrane. Once the blood is oxygenated, it drains from the alveoli by way of multiple pulmonary veins, which exit the lungs through the hilum. Q: The lungs perform gas exchange using air and what fluid, which is coming and going from the heart? A:
OPTIONS:
- mucus
- water
- saliva
- blood
blood

Answer the following question given this paragraph: greater amount of chyme at one time would overwhelm the capacity of the small intestine to handle it. The rest of the chyme is pushed back into the body of the stomach, where it continues mixing. This process is repeated when the next mixing waves force more chyme into the duodenum. Gastric emptying is regulated by both the stomach and the duodenum. The presence of chyme in the duodenum activates receptors that inhibit gastric secretion. This prevents additional chyme from being released by the stomach before the duodenum is ready to process it. Q: Gastric emptying is regulated by both the stomach and what other digestive structure? A:
OPTIONS:
- small intestine
- appendix
- esophagus
- duodenum

Answer: duodenum

Question: Answer the following question given this paragraph: Rainshadow effect occurs on the leeward side of a mountain range. Q: What side of a mountain does the rainshadow effect occur on? A:
OPTIONS:
- starboard
- windward
- due north
- the leeward side
Answer: the leeward side

input with options: Answer the following question given this paragraph: Muscle tissue that is attached to bone is skeletal muscle . Whether you are blinking your eyes or running a marathon, you are using skeletal muscle. Contractions of skeletal muscle are voluntary, or under conscious control. When skeletal muscle contracts, bones move. Skeletal muscle is the most common type of muscle in the human body. Q: What is the most common type of muscle in the human body? A:
OPTIONS:
- fetal
- internal
- digestive
- skeletal
output: skeletal

Q: Answer the following question given this paragraph: 45.3 Environmental Limits to Population Growth Populations with unlimited resources grow exponentially, with an accelerating growth rate. When resources become limiting, populations follow a logistic growth curve. The population of a species will level off at the carrying capacity of its environment. Q: While populations with unlimited resources grow exponentially, the population of a species will level off when what limit of its environment is reached? A:

OPTIONS:
- reproduction
- niche
- extinction
- carrying capacity

A: carrying capacity
