Sarah turns quickly and sees the soccer ball hurtling toward her face. She blinks and ducks for cover. During this reaction, Sar
ah perceived the ball, decided what to do, and then blinked. Which choice lists the cells that were involved in this process from first to last? A. sensory neurons, interneurons, and motor neurons (all cells that belong to the PNS)
B. motor neurons, sensory neurons, and interneurons (all cells that are part of the PNS)
C. sensory neurons (part of the PNS), interneurons (part of the CNS), and motor neurons (part of the PNS)
D. sensory neurons, interneurons, and motor neurons (all cells that belong to the CN
The given situation is the example of a Reflex Action.
Reflex action can be defined as an action shown in response to a sudden stimulus.
The CNS or the Central Nervous System is comprised of the Brain and the Spinal Cord which receives the Sensory impulses from the Receptor organ, integrates or decides on the response which needs to be provided and then sends the Response impulses to the Effector organ.
The PNS or the Peripheral Nervous System is comprised of the sensory and motor neurons those are responsible for connecting the Sensory organ and the Motor organ to the CNS, respectively.
In the situation, Sarah's eyes perceives the ball and sends sensory impulses through the optic nerve containing the sensory neurons (PNS) to the spinal cord.
The spinal cord possess inter-neurons (CNS) that decides over the action to be done in response to the stimulus.
The Response stimulus is send from the inter-neurons via the motor neurons (PNS) to the eye muscles of Sarah and Sarah performs the action, that is, she blinks.
Explanation: DNA is found in the nucleus of every cell in your body. It contains genetic information, in the form of genes, which are passed on from one generation to the next. Your DNA determines all of your traits.
With the coyotes gone, they're prey will have little to no predators. Without their numbers decreasing as quickly (because of the coyote population drop) they will be able to repopulate quicker and less of them will die. This will lead to over population.
Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.
