Question

When a stem cell differentiates and changes in size and shape, specific genes are being(1 point) Responses transcribed. transcribed. expressed. expressed. spliced. spliced. copied

Answer 1

Which of the following describes when the cell leaves the cell cycle and no longer divides?(1 point) Responses interphase interphase senescence senescence differentiation differentiation mitosis

Answer 2

Consider the three different types of stem cells. Each one’s ability to differentiate into new cells is slightly different. One type can differentiate into any cell, while another can only become specific cells. Select the answer that places the three types in the correct order, from widest range of differentiation to least able to differentiate (specific).(1 point) Responses totipotent, multipotent, pluripotent totipotent, multipotent, pluripotent pluripotent, totipotent, multipotent pluripotent, totipotent, multipotent totipotent, pluripotent, multipotent totipotent, pluripotent, multipotent pluripotent, multipotent, totipoten

Answer 3

Gene expression is determined by several factors, including(1 point) Responses chemicals in the body chemicals in the body protein synthesis protein synthesis the brain the brain senescence senescence

Answer 4

Which of the following would be an environmental factor that could affect gene expression? (1 point) Responses organ of the organism organ of the organism sex of the organism sex of the organism number of organisms in the group number of organisms in the group temperature of the water

Answer 5

When a stem cell differentiates and changes in size and shape, specific genes are being **expressed**.

Answer 6

The correct response is **senescence**.

Answer 7

The correct order from the widest range of differentiation to least able to differentiate (specific) is **totipotent, pluripotent, multipotent**.

Answer 8

The correct response is **chemicals in the body**.

Answer 9

The correct response is **temperature of the water**.
