Which would least likely result from a chromosomal change?
a. death of the cell or organism
b. no effect on the cell or organism
c. enhanced ability of the organism to reproduce
d. change to the phenotype of the organism

Answer;

c. enhanced ability of the organism to reproduce

Explanation;

-It is vital that humans have the correct balance of chromosome material. This is because the genes, that instruct the cells in our body, are found on the chromosomes.

-Any change in the number, size or structure of our chromosomes can mean a change in the amount or arrangement of genetic information.

-Human cells normally contain 23 pairs of chromosomes, for a total of 46 chromosomes in each cell. A change in the number of chromosomes can cause problems with growth, development, and function of the body's systems. These changes can occur during the formation of reproductive cells (eggs and sperm), in early fetal development, or in any cell after birth.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
