7 the table below lists specialized cells. cell specialization depends on where the cell is located as cells are layered after the blastocyst develops. specify the layer described in each column.
drag and drop the answers to the correct boxes.
:: mesoderm :: ectoderm :: endoderm
neuron brain cells
epidermal cells
pigment cells
bone tissue
red blood cells
facial muscles
lung cells
pancreatic cells
thyroid cells

Explanation:

Neurons in brain cells, epidermal cells and pigment cells develop from the ectoderm. Bone tissue, red - blood cells and facial muscles develop from the mesoderm. Lung cells, pancreatic cells and thyroid cells develop from the endoderm.

Answer:

• Neuron brain cells, Epidermal cells, Pigment cells: Ectoderm
• Bone tissue, Red blood cells, Facial muscles: Mesoderm
• Lung cells, Pancreatic cells, Thyroid cells: Endoderm
