What is considered to be the first evidence of differentiation in the cells of an embryo?
a. cell division occurring after fertilization
b. the occurrence of mrnas for the production of tissue-specific proteins
c. determination of specific cells for certain functions
d. changes in the size and shape of the cell
e. changes resulting from induction

Option (B).

Explanation:

The process of cell differentiation in the embryonic stage is important for the cell to differentiate into a specific cell type. The cell differentiation also occurs in the adult stages also.

Various experiments have been done to find the evidence of cell differentiation. The occurrence of the specific mRNAs for the formation of tissue specific proteins provide the evidence that cell differentiation occurs in the embryonic stage.

Thus, the correct answer is option (B).

the right answer is a. skin cells forming from sunlight.

the liver is an organ endowed with a fantastic ability to regenerate

. thus, if a hepatectomy (ablation) of 70% of the hepatic mass is performed in the rat, there is complete recovery in 7 to 10 days.

prokaryotes are beings that have existed since the existence of life on earth, and do not come from another realm.

ribosomes are organelles that exist naturally in eukaryotes, either in free form or attached to the endoplasmic reticulum.
