Mildred collects a sample of fossilized plant material. She takes it back to her lab to run some tests on it. 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.
explain what will happen when red blood cells is placed in hypotonic solution
Answer:
it will become turgid.
Explanation:
since the concentration of salt is less in the solution than the rbc ,due to osmosis more water enters the rbc hence making it turgid.

Where in the chloroplast does the light independent reaction occur
Answer:
In photosynthesis, the light-dependent reactions take place on the thylakoid membranes. The inside of the thylakoid membrane is called the lumen, and outside the thylakoid membrane is the stroma, where the light-independent reactions take place.

Use the attached "Story Guidelines" Handout to write an imaginative story about a
person with a heightened sense! Your story should be at least three well-developed
paragraphs long. Have fun with it and be creative...be humorous!
IMPORTANT: Use the copy of the STEMScopedia for this unit to incorporate all of the
terms related to your character's heightened sense. For example, choose a specific
type of receptor (chemoreceptor, thermoreceptor, mechanoreceptor, photoreceptor,
nocicepter or propiorecepter), and then include the terms and parts of the body
related to those receptors. Weave it into an episode in the life of your character.
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.

Which BEST describes the role of light in the overall process of photosynthesis?
A.) light observes the energy that is released by sugars
B.) light provides the energy for making small molecules into sugars
C.)light provides the energy for breaking sugars into small molecules
D.) light observes the energy that is released by small molecules
PLEASE HELP ME!!! PLEASE AND THANK YOU!!
Answer:
C
Explanation:
ight provides the energy for breaking apart sugars into small molecules. ... They absorb sunlight and transfer the energy to electrons. They form ATP as hydrogen ions cross the thylakoid membrane
Light provides the energy for making small molecules into sugars.
The correct option is B.
What is photosynthesis?Photosynthesis is the process, by which plants make their food.
The process of photosynthesis is
carbon dioxide and water combined with the help of light to produce glucose and oxygen.
The light helps in the synthesis of glucose from water and carbon dioxide.
Thus, the correct option is B. Light provides the energy for making small molecules into sugars.

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.

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.
