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. virus is able to cause an infection
Are there options? because there are lots of answers.
Firstly, eukaryotic DNA tends to be much longer; it's held inside a nucleus, so it has to be separated from the rest of the cell; and there are also mitochondria in most eukaryotic cells, which have their own RNA, which has to be separated.
Its a 50% chance that the seed will be wrinkled.
Graph and
table are similar because they both present the evidential and statistic data
given and yielded from a certain experiment or testing. They both have a role
in classification, categorization, interpretation and organization of the data.
A table can be very direct and arranged while graph can be very audience-friendly,
effective and prolific display of the results. Tables can be a system of rows
and columns while graph are representations of objects which can display
relationship however these two tools are relational with each other.
