In 2001, a small population of mice in Colorado had 150 births, 110 deaths, 12 immigrants to the population, and 2 emigrants fro

m the
population. In 2002, Colorado experienced a severe drought. In this year, the birthrate for the population remained the same (150), but there
were 140 deaths, 2 immigrants to the population, and 12 emigrants from the population. Keeping in mind the equation for growth rate (r= [B
+ 1 - [D+]), explain what the population curve would look like for this population during the period from 2001 to 2002.

It would be a U-shaped curve because the population dropped and rebounded during these years.

It would be flat because the population experienced neither growth nor decline during these years.

It would show an increase in the population in 2001 and a flat line in 2002.

It would show an increase in the population in 2001 and a decrease in the population in 2002

Answer:

Adding a lake near any town will most likely increase rainfall because of the added water, and water vapor levels will also increase. Because of the excess water in the environment, more water will be found in the surrounding atmosphere (the same reason precipitation will increase in the area.)

Why are some diseases more common in certain groups of people, such as caucasians or African Americans
Anna71 [15]

Answer:

Some diseases are more common in certain groups of people, such as Caucasians or African Americans because individuals in such ethnic groups often share certain alleles (versions of their genes), that have been passed down to them from common ancestors and a particular genetic disorder may be more frequently seen in such groups if one of these shared genes contains a disease-causing mutation.

Explanation:

Some genetic diseases are frequently seen in certain ethnic groups like Caucasians or African Americans. Individuals in such groups often share certain alleles (versions of their genes), that have been passed down to them from common ancestors and one of these shared genes may contains a disease-causing mutation.

Examples of certain genetic disorders that are more common in particular ethnic groups include the Tay-Sachs disease, which is more common in people of eastern and central Europe (Ashkenazi), Jewish or French Canadian ancestry and the sickle cell disease, which occur among people of African, African American, or Mediterranean heritage.

Some genetic disorders are more common in people whose ancestry can be traced to a particular geographic area. The factors that can lead to development of populations with very different genetic allele frequencies include their geographic origin, selection, patterns of migration, historic events, etc. Certain natural barriers like oceans and other water bodies, high mountains, large deserts, or major cultural factors had prevented communication and interaction between people. So mating was restricted within the group, and this produces genetic marker differences and differences in the presence of specific disease-related alleles.
