Polyploidy occurs when a cell contains: multiple copies of specific RNA multiple copies of the nucleus of the cell multiple copies of specific DNA multiple copies of all chromosomes Inorganic mercury after acute exposure causes: garlic odor, dermatitis, and dementia inhibition of hemoglobin synthesis gastrointestinal irritation and loss of renal function corrosive destruction of the stomach and hepatic necrosis

Solution

1. Polyploidy can be defined as multiple chromosomes as poly means many and ploidy means sets of chromosomes. So polyploidy occurs in a cell when it has multiple copies of all chromosomes.

2. An acute high dose of mercury causes primarily chest pain, darkened discoloration of the oral mucous membrane and severe gastrointestinal symptoms due to extensive corrosive damage to the GI tract leading to mercurial stomatitis and impaired kidney function.

On a whole it causes gastrointestinal irritation and impaired renal function.
