Why do heart cells have different characteristics than skin cells?(1 point)
Responses
Heart cells reproduce by mitosis.
Heart cells reproduce by mitosis.
Heart cells have different DNA than skin cells.

GPT-4o mini
The correct response is: **Heart cells express different genes than skin cells.**
While all cells in the body contain the same DNA, different cells can express different sets of genes, which leads to the development of distinct characteristics and functions in heart cells and skin cells.

The correct response is: **an organism's cells multiply many times adding mass to the organism.**
Proliferation refers to the process by which cells divide and multiply, resulting in an increase in cell number and, consequently, adding mass to the organism.

Are your heart cells the same as your brain cells? Why or why not?(1 point)
Responses
Yes, during mitosis, the resulting daughter cells are identical which means that all cells in the body are the same.
Yes, during mitosis, the resulting daughter cells are identical which means that all cells in the body are the same.
No, heart cells are stem cells that replicate and create brain cells, therefore they are two different types of cells.
No, heart cells are stem cells that replicate and create brain cells, therefore they are two different types of cells.
Yes, the heart cell and the brain cell have the same function, therefore they are identical.
Yes, the heart cell and the brain cell have the same function, therefore they are identical.
No, different sections of the cells' DNA are "tuned on" causing heart cells to have different characteristics from brain cells.
