Question: Answer the following question given this paragraph: Wave frequency is the number of waves that pass a fixed point in a given amount of time. Higher frequency waves have more energy. Wave speed is calculated as wavelength multiplied by wave frequency. Wave speed is affected by the medium through which a wave travels. Q: What is the term for the number of waves that pass a fixed point in a given amount of time? A:
OPTIONS:
- wave speed
- wave distance
- wave velocity
- wave frequency
Answer: wave frequency

input with options: Answer the following question given this paragraph: Deep currents are convection currents that occur far below the surface. They are caused by differences in the density of ocean water. Q: What are convection currents that occur far below the surface of the ocean called? A:
OPTIONS:
- subsequent currents
- waves
- flat currents
- deep currents
output: deep currents

Q: Answer the following question given this paragraph: The name carbon tetrachloride implies one carbon atom and four chlorine atoms, so the formula is CCl4. Saylor URL: http://www. saylor. org/books. Q: The name carbon tetrachloride implies one carbon atom and four of which other atoms? A:

OPTIONS:
- calcium

A: chlorine

input: OPTIONS:
- parietal lobe
- temporal lobe
- frontal lobe
- cerebellum Now, answer this question: Answer the following question given this paragraph: Brain Stem The midbrain and hindbrain (composed of the pons and the medulla) are collectively referred to as the brain stem (Figure 13.12). The structure emerges from the ventral surface of the forebrain as a tapering cone that connects the brain to the spinal cord. Attached to the brain stem, but considered a separate region of the adult brain, is the cerebellum. The midbrain coordinates sensory representations of the visual, auditory, and somatosensory perceptual spaces. The pons is the main connection with the cerebellum. The pons and the medulla regulate several crucial functions, including the cardiovascular and respiratory systems and rates. Q: What part of the brain is attached to the brain stem but considered a separate region of the adult brain? A:
A:
output: cerebellum

Question: Answer the following question given this paragraph: Figure 7.3 In this illustration of the effects of crossing over, the blue chromosome came from the individual's father and the red chromosome came from the individual's mother. Crossover occurs between non-sister chromatids of homologous chromosomes. The result is an exchange of genetic material between homologous chromosomes. The chromosomes that have a mixture of maternal and paternal sequence are called recombinant and the chromosomes that are completely paternal or maternal are called non-recombinant. Q: The chromosomes that have a mixture of maternal and paternal sequence are called what? A:
OPTIONS:
- antibodies
- gene
- DNA
- recombinant
Answer:
recombinant
