Answer: D) Segmental level, projection level, precommand level
Explanation: The hierarchical organisation of the motor control system is only one aspect, besides it there is a parallel one. The motor control system is responsible for regulating movement and as such is crucial for the body's motility, which includes directional movement and reflexes. Of course, motor control only exists in organisms that have a nervous system.
As for the hierarchy of the motor control system, the lowest in the hierarchy is the segmental level. It consists of reflexes and parts of the nervous system in charge of automatic movements.
Second in the hierarchy from the lowest to the highest is the projection level and helps in the functioning of the segmental level, i.e, for the regulation of reflexes and for monitoring the multi neuronal system.
The highest level is the precommand level, which is responsible for controlling the output impulses that control the finest, most precise movements of the body, responsible for starting and stopping movements, regulating the muscles, and preventing unwanted movements.
A comet could change course when passing a planet due to:
The four outer planets are composed of mostly gases and:
- <em>Hydrogen and Helium</em>
Since radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all emitted by the Sun, you could assume that the Sun emits a large part of the:
- <em>Gamma Rays Spectrum</em>
Answer:
D
Explanation:
people have always been farming, the great depression did not cause them to farm.
The region that's most likely at risk for a tornado is Tornado Alley. Tornado Alley consists of these U.S. states: Texas, Oklahoma, Kansas, South Dakota, Iowa, Illinois, Missouri, Nebraska, Colorado, North Dakota, and Minnesota. These states unfortunately are at the most risk of tornadoes. This is because the region allows cold air (from Canada) meet with moist and warm air (from the Gulf of Mexico), so it's soon in between two the air-masses that most tornadoes eventually form.
The region most at risk for hurricanes are states along the South; the most common places at risk are Texas, Florida, and Louisiana. You're more likely to get hit by a hurricane in these states. This is because of the mere influence from low pressure systems that cause high wind speeds on tropical systems.
