Answer:
The given statement is false. 
Explanation:
The mammals can be differentiated into three main groups on the basis of the development of their babies. These three groups are marsupials, monotremes, and placental mammals, which is the largest group. The monotremes refer to the mammals, which lay eggs. The marsupials refer to the mammals, which give birth to young ones that are not developed completely. While in a placental mammal, the development takes place within the body of a mother until and unless its systems of the body start to work on their own.

Answer:
different proteins 
Explanation:
All the cells of the body are derived from same cell still different cells have different characteristics or phenotypes. For example, the hemoglobin is present in RBCs only not in any other cell. This is because of a process called gene expression.
This process regulates expression or repression of different set of genes. This makes embryonic cells to become specialized cells that is to perform a specific function. The gene contains DNA which gets transcribed to RNA and then to proteins. The different proteins provides different specificity to cell.
