The spread of diseases is caused by pathogens.
A pathogen is an organism that is capable of causing a disease. It is not typical for a person to catch disease from pathogens in boiled water since boiling destroys pathogens.
When investigating the cause of a mysterious disease, it would not be important to determine how wealthy the diseased people were.
The place where a disease transmitted by person-to-person contact would be most likely to spread quickly is in a crowded city.
From the graph, we can see that the disease is mostly spread by person to person contact. A food borne disease is most likely to be indicated if all of the victims were friends.

B.More organisms reproduce this way.
C.Offspring grow in different environments.
D. Offspring come from identical parents.
Answer:
A. Traits from two parents are combined
Explanation:
Each time you have a sexual reproduction the offspring get a mixture of both the parents genes, making the offspring's genes unique. However since the asexual reproduction would produce an offspring with an identical genes to one parent, the genes are the same.
In other word the asexual reproduction does not have any diversity, and the sexual reproduction does because it is a mixture of two parents genes.
habitat. Use the slider to compare
its ranges in the past and today.
Why do you think the range may
have changed?
The ranges of the Greater sage-grouse have changed over time due to the expansion of human civilizations.
The Greater sage-grouse is a large hen-like bird that resides in sagebrush-covered areas. The ranges that this wild bird inhabits have historically spanned all throughout the United States and parts of Canada, including:
and many other states.
The current range of the greater sage-grouse now only spans the Western United States and parts of Canada. This decrease in range is due to loss of habitat, interrupted migration patterns by the construction of roads, power lines, etc., and other human disturbances.

Answer:
The population of sage-grouse decreases with the passage of time because of humans.
Explanation:
In the past, long time ago the population of sage-grouse bird were in millions in the Western United States of America and Canada but gradually decrease occurs in population with the passage of time due to the change which occurs in the environment by humans. Destroying the natural habitat for making buildings and for energy development decrease the population of sage-grouse from 16 million to 500,000 during 100 years.
