C.)The waste of animals returns nitrogen to the nitrogen cycle.
True. This is called cellular homeostasis. This happens when cells are able to produce and excrete materials within their environment to regulate processes like cellular respiration, phagocytosis, and pinocytosis. If cells are not able to do this, mutations and excessive cellular division may occur causing abnormalities in specific organisms.
D Or B but ima go with my gut and say D transmission of light is the moving of electromagne. waves through material. Therefore, Opaque Does not let it transmit. Transmission is reduced or stopped when light is reflected.
<h2>
Answer</h2>
Stimulus ➡ Touch Receptor ➡ Sensory Nerve cell ➡ Relay nerve cell ➡ Muscle ➡Response
<h2>
Explanation</h2>
- When a body touches a hot or very cold body, a stimulus is generated.
- Touch receptors convert this stimulus into a nerve impulse and transmit it to the sensory neurons located in the spinal cord (CNS) via peripheral nerves.
- The impulse travels across a synapse to relay neurons
- Relay neuron passes impulse across the second synapse to motor neurons.
- Now impulse travels along motor neuron to reach the effector (muscle)
- Muscle contract and hand is withdrawn quickly (Response)
