An action potential traveling along the entire length of an axon demonstrates <u>continuous</u> propagation.
Propagation of action potential:
- An action potential is created by the rapid input of Na+ ions and the slightly slower outflow of K+ ions.
- Action potential initiation occurs in the axon's first segment, and as action potentials spread throughout the axon, cells can convey their output to synapses located further distant from the cell.
- The action potential conducts continuously in unmyelinated axons, whereas it conducts rapidly and saltatorily in myelinated axons where sodium channels are concentrated near the nodes of Ranvier.
- The action potential always advances in the same direction whenever a local current begins to form due to the prior axon segment still being in the absolute refractory period. As a result, action potentials travel away from the location of their generation and do not change course.

I'm sorry if I got any wrong, I hope this helped! <3
Answer: salty and sour
Explanation:
Taste buds consist of the taste receptor cells and they're the nerve endings on the tongue that provide the sense of taste.
Based on the information given, the tastes that activate these receptors are salty and sour. The tastes depolarize the cell receptor directly.
C is the only bad sounding thing out of this bunch.
Answer: D. An adaptive process that allows children to deal more efficiently with their environment.
Explanation:
Synaptic pruning is a natural process between early childhood and adulthood which occurs in the brain. The brain removes the extra synapses during synaptic pruning. Synapses are brain structures that allow the neurons to transmit to another neuron an electrical or chemical signal.
Synaptic pruning is thought to help the brain transition from adolescence, when it can quickly learn and make new connections, to adulthood, when it is much more stable in its structure, but can concentrate on a single question for longer and conduct more complex thinking processes. Synaptic pruning make brain more adaptive to the external environment in early ages.
Hence, the correct option is D. An adaptive process that allows children to deal more efficiently with their environment.
