Answer:
a. they integrate activity within a single brain structure.
Explanation:
This can be local interneurons and relay interneuron based on function and structure.
Based on function the interneuron synapse with the sensory and motor neurons,This structural characteristic is related to their functions. Thus as sensory neurons synapse with the Interneurones, the recieved message from sensory neuron of the spinal cord first branched off to the brain for processing and analysis, and output (response) from the brain returns to the interneuron , which synapse this with the motor neurons, for transmission to the effectors.
This type of information integration and processing is especially important when processing information from high brain centers, and complex tasks,and it involved the relay interneuron. This explains the integration function within the brain structure.
However if the information is simple the local interneuron mediated this/ a sensory information is not sent to the brain. Rather the information is transmitted from the sensory to the motor , coordinated by the spinal cord and response is transmitted to the effectors.
It helps with population and reproduction.
Answer:
The cell organelle, Mitochondria will be very abundant in the wing muscles of a hummingbird.
Explanation:
Mitochondria are known as the powerhouses of the cell. They are are membrane-bound organelles which are found within the cytoplasm of the cells. They are the site for cellular respiration in the cell. The take in nutrients and breaks them down to produce energy in the form of ATP.
Actively respiring tissues and organs possess an abundance of mitochondria which produces the energy required by these tissues and organs.
Since hummingbirds require a tremendous amount of energy to flap their wings so fast, therefore, mitochondria would be very abundant in the wing muscles of a hummingbird.
