Answer:
Parasites would not want to kill their host cells immediately because they want their food source or keep getting food, not to kill their food source (host cell). Parasites live on another living host cell for their survival, they depend on host organisms to gets an energy source, without the host cell they can't live, develop and multiply.
Mostly, if the host cell dies then the parasite also can't able to grow or reproduce and it will also die. So that they don't want to kill their host's cell immediately.
Answer:
For involuntary actions (reflexes) the information is first detected in the sensor and travels along sensory neurons to the spinal cord. Once the action potential reaches the spinal cord, the information is transmitted across the synapse to the motor neuron. for voluntary actions,
movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.
Random fertilization allows random combination of genetic information, which helps synthesize genetically unique gametes. The fusion of a unique sperm together with a unique egg can introduce further variation.
