Before the action potential when the neuron is at rest, sodium channels are closed and don't allow sodium to pass-through. These channels are proteins.
What are sodium channels?Sodium channels are specific channels composed of proteins that allow the passage of sodium ions in cells (e.g., neurons).
This passage is fundamental to generating a membrane potential during the transmission of electrical impulses.
When one action potential has been produced the depolarization of cells activates sodium channels.

Use the data to explain the changes in phenotypic frequency from generation 1 to 3.
Do you think this population is in Hardy-Weinberg equilibrium? Provide reasoning to support your claim.
The phenotypic frequency from generations 1 to 3 shows there are naturally more individuals with the dominant trait. Moreover, changes in frequency show this population does not have Hardy Weinberg equilibrium.
What are the changes in phenotypic frequency?Phenotypic frequency refers to how common a trait is in one population. In this case, the number of individuals with a recessive vs those with a dominant trait.
From the information provided in the chart, we can see in the first three generations there is a higher number of individuals with a dominant trait, which is genetically natural, and this occurs even as the population grows.
Is there Hardy Weinberg Equilibrium?Hardy Weinberg Equilibrium is a principle that establishes under normal conditions phenotypic frequency should be constant. This does not occur in this population because by generation 6 there is almost the same number of individuals with a dominant and a recessive trait, which shows phenotypic frequency is changing.

The Mexican long-nosed bat roosts in Big Bend National Park in West Texas. The bat feeds on nectar and pollen and hovers while it feeds. Additionally, its tongue can extend up to eight centimeters. The features of Mexican long-nosed bats are evidence of natural selection because the features are adaptations that — lead to an increase in predation by other species of animals lead to an increase in predation by other species of animals show that most DNA mutations are necessary and advantageous but do not increase survival or reproductive success show that most DNA mutations are necessary and advantageous but do not increase survival or reproductive success help individuals outcompete other individuals for food resources to increase survival and reproductive success help individuals outcompete other individuals for food resources to increase survival and reproductive success are the result of intentional breeding
Natural selection results in adaptation, increasing in the individual's fitness. Option C. Features are adaptations that help individuals outcompete other individuals for food resources to increase survival and reproductive success.
What is natural selection?
Natural selection is an evolutive force.
It selects beneficial alleles in a population and increases their frequency.
It is the result of the phenotype-environment interaction which determines gene destiny in space and time.
Natural selection results in adaptation, meaning that it causes an increase in the aptitude phenotype.
Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring.
In many cases adaptations, resulting from natural selection can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
In the exposed example, the features are adaptations that help individuals outcompete other individuals for food resources to increase survival and reproductive success.
selective pressure ⇒ competition for resources
influence in fitness ⇒ increase survival and reproductive success.

What is contained inside the nucleus of every cheek cell?.
The content of the nucleus of every cell is DNA
NucleusThe nucleus is an organelle present in all eukaryotic cells.
The organelle contains instructions for all cellular processes.
The instructions are stored as genes, which are coded for by sequences of deoxyribonucleic acids.
Thus, since the nucleus largely contains DNA, and other molecules such as proteins, the nucleus of every cheek cell would also contain DNA.

Can the effects of UV light on folate explain the full variation of human skin color that exists among human populations today? Explain your reasoning
Human skin colour is due to a pigment called melanin. The melanin pigment is present in outer layer of skin cells. UV light causes increase in production of melanin resulting in darker skin shade.
Why the human skin colour varies?UV radiation can cause photolysis of folate. This can lower the level of folate. If the level of melanin increase, it will stop the breakdown of folate. This will result in variation of colour in high intensive UV areas.
Thus, it can be concluded that increased UV radiation can cause variation in human skin colour.
