Answer:
selective permeability

The property or characteristic of cellular membrane to allow certain substances to pass through the cell is known as selective permeability. The movement of molecules and ions across the cell can be active or passive.
Answer:
E. Gene is amplified by multiplication of cloning host
Explanation:
PCR is a very powerful technique that can help us to amplify exponentially one gene from a very small sample of DNA.
As seen in the attached image, the process begins with a single DNA molecule, for the first cycle, that DNA molecule denaturalizes into two strands, the primers bind to their complementary sides and then the DNA polymerase builds the new DNA strands. The number of copies of the gene that can be obtained with each cycle are 2ⁿ copies, where n is the cycle number.
selective breeding has changed organisms over time by paring that organism up with another organism of its kind with desirable traits. take dogs for example, through selective breeding we now have many different types of dogs with different abilities. i hope this helps
