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!
How do cats have mate? When the female cat goes into heat, the male will mount her and bite the scruff of the female cat's neck and place his penis inside her vulva. A male cat's penis has barbed riâ¦dges on it, which stimulates ovulation in the female. Then, once you hear the female let out a piercing howl, he has mated her.
