OPTIONS:
a. The organisms vary in trait
b. The variation is inherited
c. More young are born than can survive
d. Some individuals are better adapted to the environment
Answer:
d. Some individuals are better adapted to the environment
Explanation:
Kettlewell’s biological experiment, which was conducted in England, was to study the evolutionary changes taking place in trees in relation to the appearance of dark-colored moth.
It was observed that white moths were more common before the industrial revolution. After the industrial revolution, which changed the background of the environment of the moths due to pollution, the moths became easily seen and obvious to predatory birds.
It was discovered that peppered moths were selectively preyed on by birds depending on their body color, which serves as the most important factor that determines if moths can survive predation by blending with the background of their environment. This led to the evolving of moths of their color to blend with the background of their environment, which makes them hide from the birds that prey on them.
Kettlewell was trying to verify the factor in evolution by natural selection, which says, “some individuals are better adapted to the environment”.

Answer:
<em>The correct option is C) Both cloning and gene therapy are types of biotechnology.</em>
Explanation:
Gene therapy is a method in which scientists try to treat a disease by inserting a functional gene into an organism. This gene might be able to cure the disease instead of using drugs or surgery for treatment. Hence, gene therapy uses the techniques of biotechnology.
Cloning can be described as a type of biotechnology in which identical copies of a gene, tissue, organ or organism might be produces.
