Answer:
D. All of the above
Explanation:
P53 is a tumor protein. It is often referred to as the "guardian of the genome". It can stop the cell from growing, repairs DNA and controls cell death, which is called apoptosis. As the cell is cycle goes on, p53 stops the growth of the cell when there is an error or damage in the DNA. This action prevents the defective cell from replicating. The p53 then signals the production of proteins that repair DNA. If the DNA is not fixable, it programs apoptisis.
If by some chance that the p53 gene are mutated, then it cannot do those functions, which may result in cancer or the uncontrolled replication of defective cells.
The genotype in an organism is usually told by its characteristics.
so this would be things like the color of its feathers, the size and shape of the beak, etc.
Answer:
diploid organisms
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
Answer:
Ocean acidification: Ocean acidification refers to the decrease in the pH of ocean water.
The pH of ocean water decreases due to the increased in the carbondioxode emissions in the atmosphere because of the burning of fuels. This carbondioxode is dissolved in the ocean water and forms carbonic acid. This carbonic acid is responsible for increasing the pH of ocean water. In one and half century, there is 30% increase occurs in the acidity of ocean water.
