The nervous system includes the brain and spinal cord. The nervous system carries messages between the brain and the body. The division of the peripheral nervous system is responsible for receiving inputs like temperature, texture, smell, and taste. The nervous system controls things that you do not often think about, like digestion and breathing. The brain sends messages and commands back to the rest of the body through the division of the peripheral nervous system. Taste molecules are unique because different molecules trigger in the nose and mouth. Rods and are the major types of cells responsible for receiving light and translating light into nerve signals. The optic nerves "cross over" from left to right and form an "X" at the . Explain what happens in the nervous system when you touch a hot pan in the kitchen. Your explanation should begin with the perception of temperature, and end with pulling away your hand.

9. When pain & temperature receptors in skin tissue are triggered by touching a hot pan, a stimulus or impulse is generated that travels along the axons of sensory nerves in the peripheral nervous system. These impulses travel through the spinal cord to the brain where pain is perceived. The brain then sends a signal back down the spinal cord, triggering action potentials in motor neurons until it reaches the various muscles of the arm and signals to pull the hand away. This all happens in the blink of an eye.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
