2. A variety of evidence indicates that sodium channels in the axon are closed at resting potential (for the purpose of this question, assume that they all are).
Yet when we test this hypothesis by increasing the sodium concentration
outside of the cell, we consistently evoke an action potential. Explain why this
occurs.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.

We all have different forms of genes from our parent(s).what are these different forms called? a.alleles b.characters c.dna d.resources

The term life cycle includes the entire process of: adults defending their young providing a conducive environment adults producing gametes fertilization the growth of the offspring to adulthood
