Problem: OPTIONS:
- oxygen
- potassium
- lithium
- sodium
Q: Answer the following question given this paragraph: Aldosterone Recall that aldosterone increases the excretion of potassium and the reabsorption of sodium in the distal tubule. Aldosterone is released if blood levels of potassium increase, if blood levels of sodium severely decrease, or if blood pressure decreases. Its net effect is to conserve and increase water levels in the plasma by reducing the excretion of sodium, and thus water, from the kidneys. In a negative feedback loop, increased osmolality of the ECF (which follows aldosterone-stimulated sodium absorption) inhibits the release of the hormone (Figure 26.13). Q: The net effect of aldosterone is to conserve and increase water levels in the plasma by reducing the excretion of what element, and thus water? A:
Answer: sodium

Problem:OPTIONS:
- proteins
- membranes
- parasites
- antibodies

Answer the following question given this paragraph: Plasma cells are activated B cells that secrete antibodies. Antibodies are large, Y-shaped proteins that recognize and bind to antigens. Plasma cells are like antibody factories, producing many copies of a single type of antibody. The antibodies travel throughout the body in blood and lymph. Each antibody binds to just one kind of antigen. When it does, it forms an antigen-antibody complex (see Figure below ). The complex flags the antigen-bearing cell for destruction by phagocytosis . Q: What do you call large, y-shaped proteins that recognize and bind to antigens? A:
****
A: antibodies

Answer the following question given this paragraph: Vaccines are available for some infectious diseases. For example, there are vaccines to prevent measles, mumps, whooping cough, and chicken pox. These vaccines are recommended for infants and young children. Q: What is used to prevent some infectious diseases? A:
OPTIONS:
- radiation
- pathogens
- pesticides
- vaccines
vaccines

OPTIONS:
- quadrant
- cylindrical

Answer: striated

input: OPTIONS:
- moon
- the north star
- horizon
- sun Now, answer this question: Answer the following question given this paragraph: During summer in the Northern Hemisphere, the North Pole is tilted toward the Sun. The Sun's rays strike the Northern Hemisphere more directly ( Figure below ). The region gets a lot of sunlight. Summer solstice is June 21 or 22. At that time, the Sun's rays hit directly at the Tropic of Cancer (23.5N). This is the farthest north that the Sun will be directly overhead. Summer solstice in the Northern Hemisphere is winter solstice in the Southern Hemisphere. Q: During summer in the northern hemisphere, the north pole is tilted toward what? A:
A:
output:
sun
