Answer:
Totipotent Stem Cells - They can differentiate into any type of human body cell or the placenta.
Example: Fertilized egg cells.
Pluripotent Stem Cells are from totipotent cells and can differentiate into any cell in the human body; however, not many are in the placenta.
Example: Blastocyst cells.
Multipotent Stem Cells - They can only differentiate into closely related cells.
Example: Blood stem cell
Unipotent Stem Cells - They can only produce their type of cell.
Example: Skin stem cells (which can only become a new skin stem cell).

Answer:
Function of Ribosomes. Ribosomes are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes.
Explanation:
Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.
Answer:
The correct answer is option A. diploid zygote and a triploid endosperm.
Explanation:
Double fertilization is a type of fertilization that is a complex mechanism takes place in angiosperms in which a female gametophyte fuse with two male gametes. In this process, pollen grains pollinate the female reproductive structure which is the stigma of the carpel.
The double fertilization process includes two male gametes, one of the gametes fuses with the egg cell and fertilizes it which forms the zygote whereas other gamete fuses with the nuclei cell which is two in number to form the endosperm.
Thus, the correct answer is option A. diploid zygote and a triploid endosperm.
Answer:
The outcome would be one bag over the other because they would use science to disprove the others argument.
Explanation:
Ok... is this what modern science has come to?
