The correct response is: Heart cells express different genes than skin cells.
This is because, despite having the same DNA, different types of cells express different sets of genes, leading to their unique characteristics and functions.

During the healing process, stem cells can differentiate into various specialized cells that help repair and regenerate damaged tissues.
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.

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, heart cells are stem cells that replicate and create brain cells, therefore they are two different types of cells.

Although both heart cells and brain cells originate from the same DNA, they express different genes, which leads to their distinct functions and characteristics.
