<u>-The Retina</u>
<u></u>
The retina is a thin, transparent layer at the periphery of the eye's interior. Light enters the eye and is detected by specialized neural cells. The light is converted into an electrical impulse, by photosensitive rods and cones. This impulse is transmitted and interpreted by the central nervous system or CNS.
Further Explanation:
The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.
The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system;

Answer:
The effects of high altitude on humans are considerable. The oxygen saturation of hemoglobin determines the content of oxygen in blood. After the human body reaches around 2,100 meters (6,900 ft) above sea level, the saturation of oxyhemoglobin begins to decrease There’s oxygen in the air at high altitude. An increase in red blood cells in their bodies allows people to increase their body oxygen levels, especially when they perform strenuous exercise at high altitudes. Many athletes will train at high altitudes in preparation for competitions at lower altitudes. However, the human body has both short-term and long-term adaptations to altitude that allow it to partially compensate for the lack of oxygen. There is a limit to the level of adaptation; mountaineers refer to the altitudes above 8,000 meters (26,000 ft) as the death zone, where it is generally believed that no human body can acclimatize

4 shows convention because the heat is coming from out of the ground into the atmosphere
1. Axon
2. Electrons
3. A wave of reversal of the negative electrical potential inside the cell passes along the axon with ions moving in and out of the axon.
4. branch of nervous tissue was compressed, so electrical signals could no longer travel through her arm.
5. The brain sends signals to the blood vessels in the legs to dilate, so that there is increased blood flow. (This one seems the most accurate)
