Answer:

option a true

Explanation:

For depolarization to occur in a neuron, the gated sodium ion channels on the neuron membrane becomes opened to Na, allowing the flow in of sodium ion into the cell and making the cell more positive (less negative), thus depolarizing the neuron allowing action potential to be stimulated and to pass through.

Part of the study was to put landmarks that would not aid maze navigation and then remove them. Even tough the landmarks would not aid maze navigation they helped the participants in other means, probably the ones located at corners were most helpful and the ones that were there since the study started. This is explained by the fact that performance decreased when landmarks were removed that had been viewed longer.

Explain when changes in dna do and don't affect phenotypes
BabaBlast [244]
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.
