The cells in cardiac muscle would probably have a high number of
a. mrna molecules.
b. golgi apparati.
c. lysosomes.
d. mitochondria.

The correct answer would be d. mitochondria.

A mitochondrion is a membrane-bound cell organelle involved in the production of energy (ATP) for the cell.

The cardiac muscle or heart muscle is responsible for pumping blood throughout the body and thus, it works throughout life without rest.

The continuous contractions of cardiac muscle need more supply of ATP or energy as compared to any other cell of the body.

Thus, it has a high number of mitochondria so that its high energy demand can be fulfilled.

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.
