Because the three-horned alien is heterozygous, we know that three must be dominant to four, because the gene for the three horns is "hiding" the gene for four horns. Therefore, the three-horned alien has the genotype Tt (T for three horns, and t for four horns). The four horned alien must be tt, because that is the only way that a recessive trait may be seen. If you solve the punnet square on a cross between Tt and tt, you end up with half three (heterozygous) and half four (homozygous recessive) it is a bit easier to explain with something a little "closer to home" if you want me to explain it again, just say so, I don't mind!
The metal heats faster than the water because it requires less energy to heat it up (it has a lower heat capacity). 4. Why do you think different substances heat up and cool down at different rates? ... Water has a very high potential energy due the intermolecular forces between the polar water molecules.
Maintaining the genetic diversity is long term solution which help to maintain polar bear population.
Explanation:
Polar bear from Norwegian way bears are genetically unique. These bears are only who survive in the world. they have lack genetic diversity so it is possible to they stay healthy and somehow survive in worst condition.
The climate and condition of Norwegian is way better so it is necessary to relocate the other polar bear. The other important thing is to ensure about their food. Polar bear mainly eat seal but due to the melting of ice they are unable to get proper food.
The answer would be Cement,Bricks, and rock salt because in Florida they mine for hard materials
B water pollution is the answer
