Dogs can regulate their body temperature by the time they are 7 weeks old.
Dogs have remarkable internal mechanisms that maintain their body at the proper temperature at all times, irrespective of the air temperature because they are unable to endure large changes in their body temperatures.
Dogs do not perspire through the skin as people do due to their insulating coats.
A comfortable winter temperature for most dogs is between 68 and 72 degrees. The same considerations mentioned above for selecting a safe, comfortable summer temperature setting apply to selecting a winter thermostat setting.

The correct answer is option B. The scientists were studying if the mud snails can reproduce both sexually and asexually. The characteristics in the study included parameters such as the mating season, number of offspring, effect of environmental stress conditions and lack of mates. Out of all the parameters being studied can affect asexual reproduction in the mud snail but lack or presence of mates is a parameter required to be studied to determine the mode of reproduction i.e. sexual or asexual because need for mates or mate dependent reproduction occurs in case of sexual reproduction.
