Answer:
C . A cell that is surrounded by a rigid cell wall is the correct answer .
Telomeres are found at the end of chromosomes to protect
genes from reduction during replication
of chromosomes, especially during meiosis
or mitosis. They are composed of repetitive sequences
that do not code for protein. Telomeres become
reducted <span>especially due</span> to the inability of the lagging strand to be completely replicated to the end of the chromosome. However, while
the telomeres become shorted with every
replication, the telomeres are usually slightly elongated by telomerase reverse
transcriptase.
Answer: Cell division
Explanation:
Cell division can be define as the process by which the parent cell divides into daughter cells. It is the part of the cell cycle.
In multi-cellular organisms there is specialization of cells for performing different functions thus cell division is required for this purpose the cells divide and a mass of cell or tissue performs functions. These functions are necessary for the growth of the organisms.
In uni-cellular organisms the functions are few. Thus a single cell divides to produce multiple cells to produce the offspring. It is the mode of asexual reproduction.
It is an indicator of poor air quality from air pollution. This pollution is most often ozone or particulates. Typically it indicates that the air is unhealthy for children, the elderly, and sensitive groups.
