Answer:
Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.
The broad spectrum of colors can be attributed to multiple alleles. The correct option is B.
What is variation in human traits?Variation is a word used for different traits present within the species, variation occurs due to recessive and dominant genes present in the organisms and due to mutation.
Mendel gave this theory that the alleles are given independently by the parents and one become recessive and one becomes dominant.
The difference in eye color is due to these alleles. Suppose the mother has black eyes and the father has blue eyes, the child can have both alleles, but only one will show. Mutation can also cause variation, maybe the child has totally different eyes than his parents.
Thus, the correct option is B. multiple alleles.

Why is Dr. Elizabeth Cochran’s sensor important to earthquake research? How can it help develop an earthquake warning system?
Answer:
According to Cochran, these sensors become temporary seismic stations, enabling scientists to automatically monitor and retrieve data from six months to a year after an earthquake. Therefore, scientist can detect earthquake through information collected from the last earthquake.
Explanation:
Answer:
Dr. Cochran has invented a device to use on any laptop to detect an earthquake. This device can warn people about earthquakes immediately. These detectors are inexpensive and work on any computer. Scientists can create more of these sensors and distribute them to all residents in earthquake-prone areas. The sensors would let people know about earthquakes so they could go somewhere safe without wasting time.

what are 3 characteristics that adenoviruses, tv virus, and papilloma viruses have in common
Answer:
The three characteristics that adenoviruses, T7 viruses and papillomaviruses have in common include the following:
1. The three types of viruses possess icosahedral structures.
2. The viruses possess DNA.
3. Their DNA is double stranded.
Adenoviruses are naked (non enveloped) icosahedral nucleocapsid viruses, which has double stranded DNA genome. They are specific to vertebrate hosts and cause different types of diseases. T7 virus is a bacteriophage that infect bacterial cells. Most strain of E.coli are susceptible to this virus. Humanpapilloma viruses are small,naked icosahedral viruses which infect higher vertebrates.

7. Explain why there is a difference in the amount of oxygen taken in at rest and during the vigorous activity, (2
Answer:
Physical exercise leads to an increase in the arteriovenous oxygen difference in all individuals. As exercise intensities increase, the muscles increase the amount of oxygen they extract from the blood, and this therefore results in further increases in a-vO2 diff.
Explanation:
There is a difference in the amount of oxygen intake during rest and vigorous activity due to the higher amount of energy required during vigorous activity.
What is aerobic respiration?The breakdown of glucose in the presence of oxygen to generate carbon dioxide water and energy in the form of ATP and heat energy is called aerobic respiration.
Aerobic respiration is a characteristic of higher animals because of a higher level of energy required by them. The process of aerobic respiration produces higher levels of energy compared to the process of anaerobic respiration which is a characteristic of lower organisms.
When a person is performing a vigorous activity, the energy requirement increases. This increases the process of cellular respiration which requires oxygen.
Therefore, when a person is performing vigorous activity their oxygen intake is higher compared to when they are at rest.

On a graph, the vertical axis is
the y-axis and the horizontal
axis is the x-axis. Onəwhat axis
should the INDEPENDENT
VARIABLE be placed?
A
on the vertical or y-axis
B
on the horizontal or x-axis
Answer:
x-axis
Explanation:
you control those values/variables
On a cartesian plane, the independent variable belongs on the x-axis.
What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
The independent variable is the variable that is being manipulated or controlled in an experiment, and its values are typically plotted along the horizontal or x-axis.
The dependent variable, which is the variable being measured or observed in response to changes in the independent variable, is usually plotted on the vertical or y-axis.
This convention allows us to easily visualize and analyze the relationship between the two variables.
therefore, The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).
