Answer:
O and Q
Explanation:
Why O: Because gas has a lot of energy and movement and doesn't have a definite shape or volume, it can move as much as it likes, but when it condenses, it becomes a liquid, and a liquid has a definite volume, but no definite shape, and has less energy and movement.
Why Q: Because liquid has a definite volume, but no definite shape, and a good amount of energy and movement, but when it freezes it loses its energy and movement, and becomes a solid, and a solid has a definite volume and shape and the particles can barely move enough to vibrate
I hope you at least understand my concept. :)
Answer:2/4
Explanation:
Divide the total by the wrinkled
Answer:
mRNA
Explanation:
poly-deoxythymidine (poly-dT) beads binds to polyadenylated (poly (A) molecules with high affinity because Thymidine base pairs with the Adenine of the poly(A) chain.
Since messenger RNA (mRNA) is polyadenylated after transcription in contrast to other RNA species, this method is more suitable for mRNA purification.
Answer:
A. A= or RNA, B= cell fuel and support, C= galactose and glycogen,
D= nucleic acids and fatty acids.DNA
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.
