Which statement describes a disruption that can occur in the cell cycle, leading to the development of cancer?

A. A virus interferes with checkpoints within the cell cycle, resulting in slower cell proliferation.

B. A virus interferes with checkpoints within the cell cycle, resulting in uncontrolled cell apoptosis.
c. A gene mutation interferes with cell cycle control mechanisms, resulting in uncontrolled cell
proliferation.

D. A gene mutation interferes with cell cycle control mechanisms, resulting in an increased rate of cell
apoptosis.

The correct answer is - option C. A gene mutation interferes with cell cycle control mechanisms, resulting in uncontrolled cell proliferation.

Explanation:

Genetic mutations resulting in the change or absence of any regulatory proteins that used during checkpoints can result in the mechanism of turning on or turning off the cell cycle or allow a cell to move further for the division. Due to this change, the checkpoints are not able to prevent it from division.

Uncontrolled multiplication or proliferation of the cell, resulting in tumor development or cancer.

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.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.
