It is true that telomerase activity declines with old age which explains why cells lose their ability to divide after many replications.
Telomeres are DNA–protein complexes found at the ends of each chromosome they contain repetitive sequences of DNA. Telomeres protect the genome from nucleic bases degradation, unnecessary recombination, repair, and prevent the fusion of chromosomes. Telomeres, therefore, play a vital role in preserving the information in our genome.
Telomeres shorten with every consecutive DNA replication cycle limiting the number of cell divisions a cell can undergo, Telomeres act as a tumor suppressor by halting the replication of cells which contains several mutations after many division cycles.

A) 2 identical cells each with original number of chromosomes
Answer:
Fluorescence-Activated Cell Sorting or FACS is a method that allows us to sort out different cell types on the basis of fluorescence emitted by cell membrane components bound compounds.
In the case of CD95 integral protein which is known for highly glycosylated, if use antibodies against cells with CD95 marker, will not identify glycans and can’t be targeted by antibodies as antibodies only recognize protein structures.
Therefore, two different proteins should be used in order to get the correct sorting of cells. One of these would bind to these glycosylations, and the other would be antibodies (with a fluorescent tag) against first.
The olfactory system is involved in the sense of smell. The receptors of smell are not routed through the thalamus. The signals id directly routed from the olfactory bulb to the olfactory cortex and thalamus is not contacted in between. This is the difference between the taste and smell receptors, although both of their receptors are stimulated from mucus/saliva in the mouth.
