Answer:
the mouth and the oesophagus
Answer:
P - synapse
Q - Relay neuron
Explanation:
A synapse, easy to remember as a neural junction, is the site where the transmission of electric impulses occurs. This occurs between two neurons or between a neuron and a gland or muscle cell. So in this scenario when we poke the finger it fires an electric nerve impulse that gets to the P spot that is a synapse and gets transmitted to the relay neuron. A relay neuron is there to receive the signal from one neuron and then transfer it to another interneuron resulting in the signal being received by a motor neuron so that we can react to the stimulus.
Answer: Two reasons that scientists isolate DNA are for genetic testing and body identification. Inside the nucleus of every cheek cell is DNA. "Lysis" is a Greek word that means "to cut." The purpose of the detergent in the lysis solution was to disrupt the cell membrane and the nuclear envelope so the DNA is released.
