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”.
Generalized anxiety disorder
This is a chronic disorder that
involves consistent and severe worry about so many things. It is not easy for persons
with this disorder to control their worry. They anticipate and wait for the
worst even when there is no visible reason to be worried. This disorder occurs
along with other anxiety or mood disorders and it can be a long-term challenge. From the question given above, Jonah is most likely to be
diagnosed with generalized anxiety disorder.

<span>There are at least three primary functions that are performed by the epithelial tissue.Firstly it provides a great protective covering for all the tissues lying beneath it from radiation, toxins, physical trauma, desiccation and invasion of pathogens. Secondly it helps to regulate the exchange of chemicals between the body cavity and the tissues that lie underneath the epithelial tissues. It also helps in the secretion of the hormones in to the bloods. These are all major but primary functions of the epithelial tissues. From this we can easily understand the importance of the epithelial tissue
