input with options: Answer the following question given this paragraph: For natural selection to take place, organisms must vary in their traits. Asexual reproduction results in offspring that are all the same. They are also identical to the parent cell. So how can prokaryotes increase genetic variation? They can exchange plasmids. This is called genetic transfer . It may happen by direct contact between cells. Or a "bridge" may form between cells. Genetic transfer mixes the genes of different cells. It creates new combinations of alleles. Q: What is the exchange of plasmids by prokaryotes called? A:
OPTIONS:
- biochemical transfer
- artificial transfer
- transcription
- genetic transfer
output: genetic transfer

Q: Answer the following question given this paragraph: Like other arthropods, insects have three body segments and many jointed appendages. The abdomen contains most of the internal organs. Six legs are attached to the thorax. There are several appendages on the insect's head:. Q: Where are most of the organs contained in insects? A:

OPTIONS:
- head
- appendages
- thorax
- the abdomen

A: the abdomen

input: OPTIONS:
- reaction
- spasm
- sensor
- reflex Now, answer this question: Answer the following question given this paragraph: Innate Behaviors: Movement and Migration Innate or instinctual behaviors rely on response to stimuli. The simplest example of this is a reflex action, an involuntary and rapid response to stimulus. To test the "knee-jerk" reflex, a doctor taps the patellar tendon below the kneecap with a rubber hammer. The stimulation of the nerves there leads to the reflex of extending the leg at the knee. This is similar to the reaction of someone who touches a hot stove and instinctually pulls his or her hand away. Even humans, with our great capacity to learn, still exhibit a variety of innate behaviors. Q: The "knee-jerk" motion that people involuntarily perform after being struck in the knee in a certain way is an example of what kind of behavior? A:
A:
output: reflex

Answer the following question given this paragraph: Sponges come in a variety of shapes and sizes. For example, they may be shaped like tubes, fans, cones, or just blobs. They range in diameter from about a centimeter (0.4 inches) to over a meter (3.3 feet). Many species live in colonies that may be quite large. Adult sponges are sessile. This means they are unable to move from place to place. Root-like projections anchor them to solid surfaces such as rocks and reefs. Q: Root-like projections anchor adults of what colony-dwelling animals to solid surfaces such as rocks and reefs? A:

OPTIONS:
- anemones
- corals
- molluscs
- sponges

Answer: sponges

Problem: OPTIONS:
- particle depth
- density
- color
- size of sediment
Q: Answer the following question given this paragraph: Clastic sedimentary rocks are grouped by the size of the sediment they contain. Conglomerate and breccia are made of individual stones that have been cemented together. In conglomerate, the stones are rounded. In breccia, the stones are angular. Sandstone is made of sand-sized particles. Siltstone is made of smaller particles. Silt is smaller than sand but larger than clay. Shale has the smallest grain size. Shale is made mostly of clay-sized particles and hardened mud. Q: How are classic sedimentary rocks group? A:
Answer: size of sediment

Answer the following question given this paragraph: Some molecules are not able to satisfy the octet rule by making only single covalent bonds between the atoms. Consider the compound ethene, which has a molecular formula of C 2 H 4 . The carbon atoms are bonded together, with each carbon also being bonded to two hydrogen atoms. Q: The carbon atoms are bonded together, with each carbon also being bonded to two of what kind of atoms? A:

OPTIONS:
- calcium
- helium
- ions
- hydrogen

Answer:
hydrogen
