If the neuron membrane becomes more permeable to Na , Na will transport across the membrane, causing the cell to depolarize. If the neuron membrane becomes more permeable to Na , Na will transport across the membrane, causing the cell to depolarize.
A) True
B) False

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.

cuz they cant breath

explanation:

1) gene flow

- it is described as the transfer of genes from one population to another population so that frequency of gene is increased.

-a zebra migrates to join a different herd of zebras.

2) natural selection

- a mechanism of evolutionary change in which individuals with advantageous traits survive and reproduce whereas the others ( those that can not adapt) eliminate from the population.

-competition for sunlight leads to taller trees.

3) mutation

- permanent change in the nucleotide sequence of dna ( genetic material) that could have harmful or useful consequences.

-the dna of a snake changes to make its venom stronger.

4) genetic drift - it is a random phenomenon ( that occurs by chance such as fire) that results in change in the gene frequency in a small population.    

-a grassfire randomly sweeps through a population of buffalo and kills most of the animals.
