The peripheral nervous system is responsible for sensory reception and motor responses. This requires fast action potential transmission. These
impulses will travel through
A white matter and is unmyelinated
B. white matter and is myelinated
C grey matter and is unmyelinated
D. grey matter and is myelinated

B. white matter and is myelinated

Explanation:

white matter contains Axons. Impulses travel through axons. A myelinated axon transmits action potentials at a speed of about 100m/s while a unmyelinated axon transmits action potentials at a speed of about 1-10m/s

The grey matter contains the cell bodies of neurons

trachea, alveoli, lung capillaries, arteries

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
