Answer the following question given this paragraph: Emphysema is a chronic lung disease caused by the breakdown of the lung tissue. Symptoms of emphysema include shortness of breath, especially during exercise, and chronic cough, usually due to cigarette smoking, and wheezing, especially during expiration. Damage to the alveoli ( Figure below ), is not curable. Smoking is the leading cause of emphysema. Q: Emphysema is a chronic disease caused by the breakdown of the what tissue? Choices: - heart - liver - brain - lung A:
lung
Answer the following question given this paragraph: 28.5 Adjustments of the Infant at Birth and Postnatal Stages The first breath a newborn takes at birth inflates the lungs and dramatically alters the circulatory system, closing the three shunts that directed oxygenated blood away from the lungs and liver during fetal life. Clamping and cutting the umbilical cord collapses the three umbilical blood vessels. The proximal umbilical arteries remain a part of the circulatory system, whereas the distal umbilical arteries and the umbilical vein become fibrotic. The newborn keeps warm by breaking down brown adipose tissue in the process of nonshivering thermogenesis. The first consumption of breast milk or formula floods the newborn's sterile gastrointestinal tract with beneficial bacteria that eventually establish themselves as the bacterial flora, which aid in digestion. Q: The first consumption of breast milk or formula floods the newborn's sterile gastrointestinal tract with beneficial what? Choices: - disease - oxygen - pathogens - bacteria A:
bacteria
Q: Answer the following question given this paragraph: Animal behavior is any way that an animal interact with other animals or the environment. An animal may carry out behaviors alone or with other animals. The photos in Figure below show just a few of the ways that animals behave. Look at the pictures and read about the behaviors they represent. Why do you think the animals are behaving in these ways? And how do the behaviors come about? Which, if any of them, have to be learned?. Q: What is the term for any way that an animal interacts with other animals or the environment? Choices: - animal biology - animal way - immunity - animal behavior A:
A: animal behavior
Question: Answer the following question given this paragraph: Q: How long are microfilaments? Choices: - 9 nm - 4 nm - 7 m - 7 nm A:

Answer the following question given this paragraph: Reactants and products are equally abundant at equilibrium. Q: At equilibrium reactants and what are equally abundant? Choices: - results - proactives - minerals - products A:
**Answer**
products
Q: Answer the following question given this paragraph: In displacement versus time graphs, the slope of the line is the velocity of the object. In this case of a velocity versus time graph, the slope of the line is the acceleration. If you take any segment of this line and determine the to ratio, you will get 6.0 m/s 2 which we know to be the constant acceleration of this object. Q: When two of these meet, the result is often a storm? Choices: - air pockets - electromagnetic waves - tectonic plates - air masses A:
A: air masses
