A star's brightness is determined by the distance away from earth.
The gene p53, also called the guardian of the genome is located on the 17th chromosome in human genomes.
It was given this alternative name because it has a role in response to damage of DNA molecule and in preventing cancer.
The protein product of this gene stops the replication of damaged DNA, activates proteins that repair the DNA damage and if the reparation proteins fail to fix the damage it activates the process of apoptosis or so-called cell death in order to prevent the damaged cell to proliferate and potentially develop into a tumor.
Answer:
Humans cannot occupy the lowest levels.
Explanation:
Basically you have hydrophilic (water loving) and hydrophobic (water hating) the heads are hydrophilic and the tails are hydrophobic. this allows the cell to be selectively permeable. this means selectively allows or does not allow substances In or out
This is a issue of morality and ethics. So the answer to the first question depends on the perspective of the person. Personally I don't agree with performance enhancing drug use but I do think some of the expectations of athletes who perform in Olympic events increase the pressure to have to use them. So do I think people who use these drugs should be elected into the Hall of Fame. That is hard to answer. But I do not think using drugs takes away all of the achievement an athlete has made. It just proves that the athlete couldn't achieve the rigid sport performance without manipulation. But it doesn't mean they haven't worked hard or trained.
I do think rules should be made for athletes. These rules would definitely weave through most of the athletes we see doing these out of the world sport records every day. That is because many of them have been proven to have used these performance enhancing drugs.
