Answer the following question given this paragraph: All living things depend on their environment to supply them with what they need, including food, water, and shelter. Their environment consists of physical factorssuch as soil, air, and temperatureand also of other organisms. An organism is an individual living thing. Many living things interact with other organisms in their environment. In fact, they may need other organisms in order to survive. For example, living things that cannot make their own food must eat other organisms for food. Other interactions between living things include symbiosis and competition. Q: In an environment, symbiosis, competition, and relying on other organisms for food are examples of what? A:

OPTIONS:
- collaboration
- commensalism
- adaptation
- interaction

Answer: interaction

Problem: OPTIONS:
- The brain stem
- holy callosum
- disruption callosum
- corpus callosum
Q: Answer the following question given this paragraph: The Brain The brain is the part of the central nervous system that is contained in the cranial cavity of the skull. It includes the cerebral cortex, limbic system, basal ganglia, thalamus, hypothalamus, cerebellum, brainstem, and retinas. The outermost part of the brain is a thick piece of nervous system tissue called the cerebral cortex. The cerebral cortex, limbic system, and basal ganglia make up the two cerebral hemispheres. A thick fiber bundle called the corpus callosum (corpus = "body"; callosum = "tough") connects the two hemispheres. Although there are some brain functions that are localized more to one hemisphere than the other, the functions of the two hemispheres are largely redundant. In fact, sometimes (very rarely) an entire hemisphere is removed to treat severe epilepsy. While patients do suffer some deficits following the surgery, they can have surprisingly few problems, especially when the surgery is performed on children who have very immature nervous systems. In other surgeries to treat severe epilepsy, the corpus callosum is cut instead of removing an entire hemisphere. This causes a condition called split-brain, which gives insights into unique functions of the two hemispheres. For example, when an. Q: What connects the two hemispheres of the brain? A:
Answer: corpus callosum

Problem:OPTIONS:
- spiders

- crustaceans
- arachnids

Answer the following question given this paragraph: Arachnids do not have antennae or wings. Q: While similar to insects, what eight-legged invertebrates lack antennae or wings? A:

A: arachnids

Answer the following question given this paragraph: The regular, rhythmic contractions of the diaphragm are controlled by the brain stem. It sends nerve impulses to the diaphragm through the autonomic nervous system. The brain stem monitors the level of carbon dioxide in the blood. If the level becomes too high, it "tells" the diaphragm to contract more often. Breathing speeds up, and the excess carbon dioxide is released into the air. The opposite events occur when the level of carbon dioxide in the blood becomes too low. In this way, breathing keeps blood pH within a narrow range. Q: What monitors the level of carbon dioxide in the blood? A:
OPTIONS:
- the lungs
- the heart
- the kidneys
- the brain stem
the brain stem

Answer the following question given this paragraph: The table salt pictured in the Figure below contains two elements that are so reactive they are rarely found alone in nature. Instead, they undergo chemical reactions with other elements and form compounds. Table salt is the compound named sodium chloride (NaCl). It forms when an atom of sodium (Na) gives up an electron and an atom of chlorine (Cl) accepts it. When this happens, sodium becomes a positively charged ion (Na + ), and chlorine becomes a negatively charged ion (Cl - ). The two ions are attracted to each and join a matrix of interlocking sodium and chloride ions, forming a crystal of salt. Q: Another name for table salt is? A:
OPTIONS:
- hydrogen chloride
- carbon chloride
- dioxide chloride
- sodium chloride

Answer: sodium chloride

input with options: Answer the following question given this paragraph: An experiment is a controlled scientific study of specific variables. A variable is a factor that can take on different values. For example, the speed of an object down a ramp might be one variable, and the steepness of the ramp might be another. Q: In a controlled scientific study, what do you call a factor that can take on different values? A:
OPTIONS:
- output
- input
- vector
- variable
output:
variable
