Mildred is able to measure the amount of carbon-14 in her sample and compare this to the amount of carbon-12 in it. She uses this information to calculate that the fossil is 4,500 year old. The process that Mildred used is known as _______
Radiocarbon dating
Faulting
Indexing
Superposition
Explanation:
Radiocarbon dating is a process of determining the age estimates of various objects and materials using the radioactive properties of an isotope of carbon, carbon-14.
Radiocarbon dating uses the ratio of two isotopes of carbon, carbon-12 and carbon-14 present in materials which contains carbon to determine their age.
There is a fairly constant ratio of carbon-12 and carbon-14 in living organisms. However, at death, due to the decay of carbon-14 to carbon-12, the ratio begins to change. Since the rate of decay of carbon-14 is fairly constant, a property known as half-life, the time it has taken for carbon-14 to decay to carbon-12 can be calculated. This calculated time will givee the age of the fossilised material.

If the mrna is damaged, it directly interferes with the ability of a animal cell to do which of the following?
Answer:
Proteins.
Explanation:
If the mRNA is damaged, it directly interferes with the ability of producing proteins in animal cell because mRNA is responsible for carrying the protein blueprint from a cell's DNA to its ribosomes which are considered as the machines of the cell that produces proteins for the cell. These messenger RNA has the information about what type of proteins are required to produced for the cell. So if mRNA is damaged, the ribosomes are unable to produce proteins for the cell.

concentration of solute (dissolved stuff) than
An Isotonic solution has a(n)
inside the cell.
Lower
Higher
Equal
Answer:
higher is the concentration of solute
The liquid having the highest solute concentration. Hypotonic: A solution with a low solute content. Thus, option B is correct.
What concentration of solute (dissolved stuff) than isotonic?When two liquids with varying solute concentrations are compared, the higher solute concentration solution is hypertonic, whereas the lower solute concentration solution is hypotonic. The solute concentration in isotonic solutions is the same.
A solution that has the same concentration as another solution is said to be isotonic.
A solution that contains the same amount of salt as blood and cells. Isotonic solutions are typically used as intravenous fluids in hospitalized patients.
Equal amounts of each solution will flow across a semipermeable membrane separating two solutions. Because the solvent and solute concentrations are the same.
Therefore, higher is the concentration of solute.

What happens when sunlight is passed through a prism?
We can see UV rays.
We can see infrared rays.
Visible light separates into different colors.
Visible light splits to form the electromagnetic spectrum.
Answer:
As light passes through a prism, it is bent, or refracted, by the angles and plane faces of the prism and each wavelength of light is refracted by a slightly different amount. ... As a result, all of the colors in the white light of the sun separate into the individual bands of color characteristic of a rainbow.

Viruses are particles that Select one: a. contain DNA or RNA which can be injected into a cell. b. have an exterior coat composed of protein. c. can contain an enzyme which catalyzes the reaction to make DNA from the viral RNA. d. All of these answer choices are correct.
Answer:
d. All of these answer choices are correct.
Explanation:
Viruses have an exterior coat composed of protein, the capsid. Inside of it, there is DNA or RNA. When the virus has RNA, it has an enzyme that allows the synthesis of DNA from RNA. This type of virus is a retrovirus since it does the inverse process, from RNA, it gives DNA and not the other way round.
First, as the capsid has proteins, it attaches to a receptor in the cell's membrane. Then the DNA or ARN enters the cell taking it as a host since it uses the cell's structure to replicate the viral DNA and make viral proteins and DNA that then it assembles to form new viruses that will be released to infect other cells.

The diagram represents the Moon and its orbit around Earth. The arrow labeled X represents the force that keeps the Moon in its orbit. Which force is represented by X?
Answer:
A. Gravity
Explanation:
The strong gravity, or "Pull" of the Earth is what keeps the moon in orbit.
I hope this helps!
Gravity is the force represented by X that keeps the Moon in its orbit. Therefore, option (A) is correct.
What is gravity?Gravity is a force that attracts two objects with mass towards each other. It is the force that gives weight to physical objects and is responsible for the friction between objects and the surface of the Earth.
The strength of the gravitational force between two objects depends on their mass and the distance between them. The greater the mass of the objects, the stronger the gravitational force between them. The farther apart the objects are, the weaker the gravitational force between them.
The most familiar example of gravity is the force that attracts objects towards the surface of the Earth. The Earth has a large mass, so it has a strong gravitational pull. This is why objects on the surface of the Earth are "weighted" and feel heavy.
