Answer:
Telomeres cap and protect the ends of chromosomes from degradation and illegitimate recombination. ... Abolition of telomerase activity in such cells nevertheless results in telomere shortening, a process that eventually destabilizes the ends of chromosomes, leading to genomic instability and cell growth arrest or death.

Why does your heart have to pump your blood to your lungs BEFORE it can pump it to the rest of the body?
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
what is responsible for pumping blood to the lungs?
The oxygen-poor blood fills the right atrium and then flows to the right ventricle, where it is pumped to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, which comes from the air that you breathe in.
Answer :Aneuploidy often results in serious problems such as Turner syndrome, a monosomy in which females may contain all or part of an X chromosome. Monosomy for autosomes is usually lethal in humans and other animals. Klinefelter syndrome is a trisomy genetic disorder in males caused by the presence of one or more X chromosomes. The effects of trisomy are similar to those of monosomy. Down syndrome is the only autosomal trisomy in humans that has a substantial number of survivors one year after birth. Trisomy in chromosome 21 is the cause of Down syndrome; it affects 1 infant in every 800 live births
