Best Answer: yes carbon dioxide is a pure substance, provided there is nothing else in it. as soon as you add some oxygen (O2) or methane (CH4) etc it is not pure. the actual molecule is CO2, one carbon and 2 oxygen atoms everytime which makes it pure. it is the same as saying pure salt. salt has sodium and chlorine in it but is still a pure substance provided nothing else is in it.
Yes, mother cats do mate with their offspring. I had cat which had become so old that my family members used to call her grandmother cat. I had once seen her mating with her offspring and THEIR offspring at different times!
Within two days after mating the femaleâs eggs will become fertilized and the queen will officially be pregnant within a little over a week. It is actually possible for a female cat to become pregnant by several different male cats at once since the period of heat can last over a week.our first choice may be to buy some earplugs and lock your cat in a room, but thatâs not going to solve the problem in the long term. There are a few things you need to understand about why cats go into heat, for how long, how often, and how it can be stopped permanently.
