Answer:
1) To form a multicellular organism, a zygote must divide into 16 cells which produces ball structure called a morula. After that, morula is converted into a structure called blastula.
2) Adult stem cells are responsible for the maintenance of tissues and repair the damage tissues in the body. It is also called somatic stem tissue. It increase in number through cell division.
Answer:
Prokaryotes are organisms that consist of a single prokaryotic cell. Eukaryotic cells are found in plants, animals, fungi, and protists. They range from 10–100 μm in diameter, and their DNA is contained within a membrane-bound nucleus. Eukaryotes are organisms containing eukaryotic cells.

Answer:
Microchimerism is implicated in autoimmune diseases. This phenomenon, called microchimerism, is known as one that can provoke several autoimmune disorders, such as lupus and rheumatoid arthritis.
Explanation:
Chronic disease is a condition of human chimerism that shares similarities with some autoimmune diseases. Chimerism has been known to play a role in the pathogenesis of autoimmune diseases. Chimerism indicates the presence of cells from one individual in another individual. Chimeric cell injection causes lupus-like disease. Regarding all of this we can see that chimerism provokes autoimmune deseases.
