Answer:
C genetic drift
Explanation:
variation in the relative frequency of different genotypes in a small population, owing to the chance disappearance of particular genes as individuals die or do not reproduce.

Answer:
The purple flower is a dominant trait.
It can be explained with the help of the law of dominance which states that the trait which expresses itself and masks the other in a heterozygous condition is called a dominant trait.
When two purebred parents for a particular trait (like flower color in this case) are crossed, it always results in a heterozygous offspring. The trait which is expressed in the heterozygous condition is said to be a dominant trait.
Like in this case, the offspring had purple flowers. Thus, the purple flower is a dominant trait.
Answer:
The mutated protein would be the target for the new drug therapy.
Explanation:
Cancer occur due to mutation in some important genes that regulate cell cycle as well as cell division.The mutation of tumor suppressor gene such as retinoblastoma,p53,PTEN etc also leads to the onset of cancer.
Now the most important point to note that mutation in the these particular genes result in the formation of abnormal proteins or disease causing proteins.These mutated proteins are the principle cause for the occurrence of cancer.
As a result the mutated protein would be appropriate target for the new drug therapy .The drug will interact with the mutated protein and blocks the toxic activity of the later.
Answer:
from the intermembrane space to the matrix
Explanation:
In the electron transport chain (ETC), electrons flow from one protein complex to another. However, as this electrons are transfered, protons (H+) is built up from the intermembrane space of the mitochondria to the mitochondrial matrix.
Hence, according to this question, a proton gradient is formed when hydrogen ions (H+) are moving from the intermembrane space to the matrix of the mitochondrial.
