Answer:
The process that Mildred used is known as Radiocarbon dating
Note: The question is incomplete. The complete question is given below:
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.
Answer:
The correct answer is between the arachnoid and the pia. Thus option 'a' is correct.
Explanation:
Subarachnoid hemorrhage is the bleeding in the brain more precisely in the subarachnoid space-the space between the arachnoid and the pia matter surrounding the brain.
The layers that surround the brain termed as meninges of the brain of the brain include:
1) Dura matter the outermost layer close to the skull.
2)Arachnoid matter.
3) Pia matter, the innermost layer that is in contact with the brain.
A subarachnoid hemorrhage can occur due to many causes such as an accident , ruptured aneurysm, e.t.c. It is a life threatening condition and is accompanied with stroke.
At first glance cycads and palm trees look very similar. How are they distinguished? a. Cycads have cones, and palm trees, a gnetophyte, have single large fruits.

Answer:
The macromolecule structure of everything would be different and so would the function because everything would need to be structured in a way that it won't just dissolve when the nonpolar lipid will touch things.
