Question

1. before new medicine is approved, scientists study the effects the medicine has on different parts of the body. often, a medicine is tested on mice before it is tested on humans. all the cells in the illustrations below came from the same mouse. why do the cells of mouse all look different? cells change shape as they get older different cells specialize in different functions each kind of cell is from a different organ system different - shaped cells came from different ancestors.

Explanation:

Cell specialization (differentiation) leads to cells having different shapes and functions. All cells in an organism (like the mouse) come from the same ancestor (zygote). Cell shape change here is due to specialization for functions, not just aging. Also, cells from different organ systems in the same organism still result from specialization.

Answer:

Different cells specialize in different functions.
