_____ is a binocular cue used to judge distance and depth based on the tension of the muscles that direct where the eyes are focusing.
Answer:
An important binocular depth cue is convergence, the inward turning of our eyes that is required to focus on objects that are less than about 50 feet away from us. The visual cortex uses the size of the convergence angle between the eyes to judge the object's distance.

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.

Meredith is 5-years-old. She has a genetic condition known as xeroderma pigmentosum, which makes her extremely sensitive to UV light. If she goes outdoors, she must have all her skin covered and wear a hat and sunglasses. Based on her condition she is most likely to ________. Select all that apply.
From what we know, if Meredith goes outside unprotected, she is most likely to develop skin cancer.
How does this happen?Meredith does not have natural protection against the UV light from the sun. This light causes mutations at a genetic level. These mutations cause the cell to grow rapidly and without end, turning it into a cancerous cell.
Therefore, we can confirm that among many other illnesses and side effects, Meredith is most likely to develop skin cancer due to the UV light.

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.

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.
