Answer the following question given this paragraph: Descending fibers from the cerebrum have branches that connect to neurons in the pons. Those neurons project into the cerebellum, providing a copy of motor commands sent to the spinal cord. Sensory information from the periphery, which enters through spinal or cranial nerves, is copied to a nucleus in the medulla known as the inferior olive. Fibers from this nucleus enter the cerebellum and are compared with the descending commands from the cerebrum. If the primary motor cortex of the frontal lobe sends a command down to the spinal cord to initiate walking, a copy of that instruction is sent to the cerebellum. Sensory feedback from the muscles and joints, proprioceptive information about the movements of walking, and sensations of balance are sent to the cerebellum through the inferior olive and the cerebellum compares them. If walking is not coordinated, perhaps because the ground is uneven or a strong wind is blowing, then the cerebellum sends out a. Q: Descending fibers from the cerebrum have branches that connect to neurons in the pons. those neurons project into the cerebellum, providing a copy of motor commands sent to this? Choices: - neurotransmitters - umbilical cord - cerebral cortex - spinal cord A:
spinal cord

Answer the following question given this paragraph: As shown in Figure below , the tip of a root is called the root cap . It consists of specialized cells that help regulate primary growth of the root at the tip. Above the root cap is primary meristem, where growth in length occurs. Q: Where does growth in length occur, above the root cap? Choices: - primary tuber - vascular cambrium - apical meristem - primary meristem A:
**Answer**
primary meristem

Answer the following question given this paragraph: Like hurricanes, winter storms develop from cyclones. But in the case of winter storms, the cyclones form at higher latitudes. In North America, cyclones often form when the jet stream dips south in the winter. This lets dry polar air pour south. At the same time, warm moist air from the Gulf of Mexico flows north. When the two air masses meet, the differences in temperature and pressure cause strong winds and heavy precipitation. Blizzards and lake-effect snow storms are two types of winter storms that occur in the U. S. Q: Hurricanes and winter storms both develop from what, which often form when the jet stream dips south in the winter? Choices: - tides - waves - typhoons - cyclones A:
(Answer)
cyclones
