Explanation:

jeremy is digging in the garden. he feels the spade hit a rock and stops digging immediately. explain how sensory, relay and motor neurons would function in this situation.

Answers

relay neurones allow sensory and motor neurones to communicate with each other. They would decide how to respond to the sensation of the spade hitting the rock by acting between the sensory and motor neurones.

Final answer:

In the situation where Jeremy is digging in the garden and feels the spade hit a rock, the functioning of sensory, relay, and motor neurons is crucial in his body's response to this stimulus.

Explanation:

When Jeremy was digging in the garden, he felt the spade hit a rock. This is sensation was facilitated by sensory neurons which picked up the external stimulation and sent the information in the form of electrical impulses from the nerves in his hands towards his spinal cord and brain. This sensory information travels to the brain via relay neurons, which are also known as interneurons. They reside within the central nervous system and transmit the signals from sensory neurons to appropriate areas of the brain for processing.

Upon processing the sensory data, the brain forms a motor response which is relayed back towards the muscles in his arms to stop digging. The 'stop digging' response is sent through motor neurons, which transmit the signals from the brain to the muscles in Jeremy's arms, causing him to stop the movement of the spade.

Gene expression in prokaryotes is regulated at which stage?

Answers

Gene expression in prokaryotes can be regulated at multiple stages including transcriptional and co-translational. Operons respond routinely to the presence of specific metabolites and change the availability of activators and repressors while speific end products of biosynthetic pathways can regulate the translatability of mRNAs for new proteins.
