Answer:
Reflexes are not a function of the spinal cord.
Explanation:
The spinal cord is part of the central nervous system and is made up of neurons that go along it (from the end of the brain stem almost to the bottom of the spine).
The spinal cord receives incoming messages from the peripheral nervous system (including the sensory neurons) and pass on messages from the brain to efferent neurons (motor neurons at muscles).
The spinal cord contributes to learning as it passes on the info received from sensory neurons (that there is an obstacle in the path) to the brain and passes on the response from the brain to the muscles (to lift the foot up higher).
The spinal cord is essential for integration as it passes on sensory information to the brain to determine motor output.
Reflexes are when sensory information is quickly sent straight to motor neurons to move. It does not need to go to the brain (hence does not need to go to the spinal cord) for the reaction as it would be too slow. This is seen when someone who is paraplegic (paralysed at lower torso) can still move their leg in response to the doctor tapping their knee even when they cannot forcibly move their legs.
Therefore reflexes are not a function of the spinal cord.
Because the energy is going to decrease to also nothing and the animals at the top have to hunt more than those closer to the bottom of the food web
Answer:
The animals adapt to survive.
Explanation:
If a giraffe can't reach the food that another one can, that giraffe will die and the longer necked one wll survive. Adaptations over time cause evolution. The fittest will survive. (Darwinism)
Answer:
<u>Perilymph</u> is a fluid similar to cerebrospinal fluid that fills the space between the bony labyrinth and the membranous labyrinth.
Explanation:
The inner ear consists of the bony labyrinth and the membranous labyrinth, it is filled of endophilia and surrounded by perinfilia (the bony labyrinth surrounds the membranous, between both there is a space occupied by the perilymph). Perilymph is an albuminous fluid that has an ionic composition similar to the extracellular environment, it bathes the tympanic and vestibular ramps, fully occupying the bony cavities of the inner ear, bathing the membranous parts located inside these cavities.
