20. (5 points) An unemployed science teacher decided to make a
house out of 2" (5 cm) pink foam
board. He made the house in the
shape of a box that was 3 meters
long, 2.6 meters wide, and 2 meters
high. How much power will an
electric heater need to keep the
house at 22°C (72°F) if the outside
air temperature is -2°C. You can
assume that the heat loss from
conduction is the main factor. (W)
[kpink foam = 0.03 W/m/°C]

explanation:

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
