Answer the following question given this paragraph: The fovea is the region in the center back of the eye that is responsible for acute vision. The fovea has a high density of cones. When you bring your gaze to an object to examine it intently in bright light, the eyes orient so that the object's image falls on the fovea. However, when looking at a star in the night sky or other object in dim light, the object can be better viewed by the peripheral vision because it is the rods at the edges of the retina, rather than the cones at the center, that operate better in low light. In humans, cones far outnumber rods in the fovea. Q: What is the region in the center back of the eye that is responsible for acute vision? Choices: - cornea - lens - pupil - fovea A:
fovea
Answer the following question given this paragraph: The disaccharides differ from one another in their monosaccharide constituents and in the specific type of glycosidic linkage connecting them. There are three common disaccharides: maltose, lactose, and sucrose. All three are white crystalline solids at room temperature and are soluble in water. We'll consider each sugar in more detail. Q: Maltose, lactose, and sucrose are common types of what, which are distinguished by their monosaccharide constituents? Choices: - silicates - oxides - precipitates - disaccharides A:
disaccharides
Q: Answer the following question given this paragraph: Planets are held in their orbits by the force of gravity. What would happen without gravity? Imagine that you are swinging a ball on a string in a circular motion. Now let go of the string. The ball will fly away from you in a straight line. It was the string pulling on the ball that kept the ball moving in a circle. The motion of a planet is very similar to the ball on a string. The force pulling the planet is the pull of gravity between the planet and the Sun. Q: What force holds planets in their orbits? Choices: - magnetism - centrifuge - Big Bang - gravity A:
A: gravity
Question: Answer the following question given this paragraph: Phospholipids are the major components of cell membranes. Q: What is the name of the major components of cell membranes called? Choices: - antibodies - cytoplasm - eukaryotes - phospholipids A:
Answer: phospholipids

Answer the following question given this paragraph: Gain-of-function mutations result in the gene product or protein having a new and abnormal function and usually result in a dominant phenotype. Examples of gain of function mutations occur in the thyroid hormone receptor gene. Q: What phenotype do gain-of-function mutations usually result in? Choices: - submissive - internal - external - dominant A:
**Answer**
dominant
Q: Answer the following question given this paragraph: In a wheel and axle, force may be applied either to the wheel or to the axle. This force is called the input force. A wheel and axle does not change the direction of the input force. However, the force put out by the machine, called the output force, is either greater than the input force or else applied over a greater distance. Q: What is the term for the force applied to a wheel and axle? Choices: - velocity force - momentum - output force - input force A:
A: input force
