_____ 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.

Question: How does the number of wire coils on an electromagnet affect the strength of magnetic force?
do Hypothesis and the Reasoning for Hypothesis
PLS HELP
Answer:
here's your answer hope it helps you
Explanation:
the strength of magnet increase with increasing number of turns in the coil.
the strength of the electromagnet is directly proportional to the number of turns in the coil. if you double the number of turns, you double the strength of the electromagnet.
The number of wire coils on an electromagnet affects the strength, as the strength is directly proportional to the number of turns in the coil.
What is an electromagnet?An electromagnet is a type of magnet where an electric current creates a magnetic field. The wire that makes up an electromagnet is typically twisted into a coil. A magnetic field is produced by a current flowing through the wire and is concentrated in the hole at the center of the coil.
As the coil's turns grow, the magnet's strength does as well. The coil's number of turns directly relates to the electromagnet's strength. The electromagnet's strength doubles when the number of rotations is doubled.
Therefore, since the strength is inversely related to the number of turns in the coil, the number of wire coils on an electromagnet affects its strength.

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.

__________ are supporting cells with paddle-shaped protrusions that help produce the myelin sheath insulating neurons in the central nervous system.
We can confirm that the supporting cells with paddle-shaped protrusions that help produce the myelin sheath-insulating neurons in the central nervous system are Oligodendrocytes.
Why are these cells important?As mentioned, these cells produce the myelin cover to protect the axons of neurons in the central nervous system. This cover is essential to promote the impulses needed to carry out the most basic functions on a day-to-day basis. The absence of this coverage can lead to many illnesses.
Therefore, we can confirm that the cells being described in the question are nonother than the Oligodendrocytes of the central nervous system.

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.

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.

In order to change an observable characteristic of an organism, one would only need to change the DNA ________.
Answer: Sequence
Explanation: DNA exists like a code and if you had a chain like ATGC and rearranged it to be AGCT, they could represent two very different forms of a trait like hair color, one is blond and one is brown, but they are both made of the same puzzle pieces.
In order to change an observable characteristic of an organism, one would only need to change the DNA sequence that codes for that characteristic.
How traits of an organism are determined ?Observable characteristics or traits of an organism are determined by the genes present in the organism's DNA. Changes to an organism's observable characteristics can occur when there are changes in the DNA sequence.
The DNA sequence provides instructions for the synthesis of proteins, which are responsible for the structure and function of cells and tissues in an organism.
A change in the DNA sequence, such as a mutation, can lead to changes in the amino acid sequence of a protein, which can alter its structure and function. If the protein is involved in a biochemical pathway that controls a particular trait, then the change in its structure and function can result in a change in the observable characteristic of the organism.
For example, the gene responsible for the production of melanin determines the color of an organism's skin, hair, and eyes. Any changes in the DNA sequence of this gene can affect the production of melanin, resulting in changes in the observable characteristics of the organism's skin, hair, and eyes.
Therefore, to change an observable characteristic of an organism, one would need to change the DNA sequence that codes for that particular characteristic.

4. What could happen to our local environment if a company pumped materials into the
atmosphere which created a drastic pH change in the rain water?
Answer:
It would upset the balance of the environment and cause animals to die off from the toxic and then other animals would die since they were eating the animals that had died.
If a company pumped materials into the atmosphere which created a drastic pH change in the rainwater, it could have a number of negative impacts on the local environment like acid rain, eutrophication, risk of respiratory illness, and decreased visibility.
Acid rain: Rainwater with a pH of less than 5.6 is considered acid rain. Acid rain can damage trees, plants, and crops. It can also corrode buildings and infrastructure.
Eutrophication is the process of excessive nutrient enrichment in a body of water, leading to the growth of algae and other aquatic plants. This can deplete the oxygen levels in the water, killing fish and other aquatic life.
Increased risk of respiratory illness: Acid rain can irritate the lungs and airways, leading to respiratory problems such as asthma and bronchitis.
Decreased visibility: Acid rain can also reduce visibility, making it difficult to drive, fly, and see clearly.
The specific impacts of a drastic pH change in the rainwater would depend on the materials that were pumped into the atmosphere and the amount of material that was pumped. However, the impacts would likely be negative and could have a significant impact on the local environment.
