Question

which statement is true for specialized cells?
they have the ability to differentiate into new cells.
bone marrow and adult stem cells are examples.
stem cells are formed when specialized cells reproduce.
their function is determined by the gene expressed.

Explanation:

Specialized cells have specific functions determined by gene expression. Stem cells are undifferentiated and can differentiate into various cell types, not the other way around (stem cells produce specialized cells, not vice - versa). Bone marrow contains stem cells (like hematopoietic stem cells), but adult stem cells are a broader category. While some cells can differentiate (like stem cells), for specialized cells, their function is set by gene expression.

Answer:

Their function is determined by the gene expressed.
