Answer the following question given this paragraph: You generally can't see, smell, taste, hear, or feel radiation. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one pictured in the Figure below , contains atoms of a gas that is ionized if it encounters radiation. When this happens, the gas atoms change to ions that can carry an electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. You can see a video about the Geiger counter and how it was invented at the URL below. Q: What does the geiger counter detect? A:
OPTIONS:
- vibration
- convection
- moisture
- radiation

Answer: radiation

Question: Answer the following question given this paragraph: Circadian rhythms are regular changes in biology or behavior that occur in a 24-hour cycle. In humans, for example, blood pressure and body temperature change in a regular way throughout each 24-hour day. Q: What are regular changes in biology or behavior that occur in a 24 hour cycle? A:
OPTIONS:
- cognitive rhythm
- auditory rhythm
- life cycle
- circadian rhythm
Answer: circadian rhythm

input with options: Answer the following question given this paragraph: Birds have a sac-like structure called a crop to store and moisten food that is waiting to be digested. They also have an organ called a gizzard that contains swallowed stones. The stones make up for the lack of teeth by grinding food, which can then be digested more quickly. Both structures make it easier for the digestive system to produce a steady supply of nutrients from food. Q: Where do birds store and moisten food that is waiting to be digested? A:
OPTIONS:
- nest
- tree
- gullet
- crop
output: crop

Q: Answer the following question given this paragraph: Spermatogenesis As just noted, spermatogenesis occurs in the seminiferous tubules that form the bulk of each testis (see Figure 27.4). The process begins at puberty, after which time sperm are produced constantly throughout a man's life. One production cycle, from spermatogonia through formed sperm, takes approximately 64 days. A new cycle starts approximately every 16 days, although this timing is not synchronous across the seminiferous tubules. Sperm countsthe total number of sperm a man producesslowly decline after age 35, and some studies suggest that smoking can lower sperm counts irrespective of age. The process of spermatogenesis begins with mitosis of the diploid spermatogonia (Figure 27.5). Because these cells are diploid (2n), they each have a complete copy of the father's genetic material, or 46 chromosomes. However, mature gametes are haploid (1n), containing 23 chromosomesmeaning that daughter cells of spermatogonia must undergo a second cellular division through the process of meiosis. Q: How many chromosomes do mature gametes contain? A:

OPTIONS:
- 19
- 13
- 17
- 23

A: 23
