Which advance in biology resulted from developments in cell technology?
a- somatic cells
b-immortal cell lines
c- aseptic technique
d- tissue typing

Ans.

The immortalised cell lines are defined as the cell population, form of a multicellular organism that would usually do not proliferate indefinitely, but have escaped normal cell senescence due to mutations. Thus, these cells keep undergoing indefinite divisions.

The immortalised cell lines can be also developed in vitro by using advance cell technologies. These technologies include hybridoma technology, artificial expression of proteins that make cells immortal, and introduction of mutations in normal cells.  

Thus, the correct answer is option B). 'immortal cell lines.'

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs.
