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:
Cells would most probably not exist because these units of life metabolize energy molecules like glucose to harness their energy for the running of biochemical processes, like active transport, to support life. However, harnessing this energy from these energy molecules is NOT 100 percent efficient. A higher percentage of energy is lost as heat in the process.
Therefore if the cells were required to carry all molecules in and out of the cell, actively, including the energy molecules themselves (which is counterintuitive), this would require a lot of energy and would be unsustainable. This would be analogical to the counteracting and infinite loop of more fuel needed to carry the mass of the more fuel in space travel...

No. animal cells are not as mobile as bacteria, which means they don’t need a flagellum. Animal cells do not need a cell wall- as the cell wall is primarily used to maintain structure, which is needed in photosynthetic plants. please give this brainliest!
Gene therapy is replacing defected genes with new ones, the goal is to be able to cure some diseases caused by defected genes or make them better
