<h2>
Meselson and Stahl conducted an experiment to determine the correct proposed methods of DNA replication was semi-conservative
. the three proposed models for DNA replication are semi-conservative, conservative, and dispersive.</h2>
Explanation:
In Semi-conservative replication model, the two strands of DNA uncoil from each other. It perform with the original strand and a new strand.
In Conservative replication model, DNA replication didn't open at all, but the parent strands remains undamaged by creating a new and separate molecule that consists of two new strands.
In Dispersive replication model, DNA replication results in two DNA molecules that consists of both parental and daughter DNA.
He demonstrated that semi-conservative DNA replication is an universal mechanism allocated by all organisms on Earth.
Answer:
rain is very important for life in certain areas, this is why you see little life in deserts and even they need rain occasionally. more rain will lead to more life, first, it will be the plants that move in, then once they grow, vegetation eaters will move in, then after that meat-eaters will move in to eat those creatures and the ecosystem will flourish.
Answer: It will slow down.
Explanation: This is because the same amount of blood that usually goes through will have to fit through a blocked vessel. Only a little will be able to go through at one time, causing the blood flow on the other side to slow.
(That is really dangerous. The build-up will eventually burst the vessel) Just an FYI
Scientific Theory change but not thrown away because scientist
continue looking for possibilities and exact proportion to prove such theory,
though it is change because they always conducted hypnosis in every theory and
once it proves something different they conduct another hypothesis for more
actual evidence.
