Answer:
translocation occurs between non-homologous chromosomes.
Explanation:
Ice forms from the top of the water column down, creating a protective barrier over the liquid water.
The higher-density liquid water shelters organisms from cold air better than the less-dense ice.
The higher-density liquid water traps nutrients for primary producers better than the less-dense ice.
Answer:
The higher-density liquid water shelters organisms from cold air better than the less-dense ice.
Explanation:
Because of this difference in density, the waters of lakes and seas do not freeze completely because a less dense ice layer forms on the surface and creates a natural thermal insulator that makes the water below it remain in the liquid phase. This saves the animal and plant life of lakes and seas.
Ice works as a thermal insulator because its specific heat (2.03 J/g. ºC) is lower than that of water (4.18 J/g. ºC).
After the cold is over and the hot season comes, the surface ice melts easily. But that would not happen if the ice dropped to the bottom of lakes and seas. With this, the animal and plant life would be compromised.
Another important point is that, as already mentioned, liquid water reaches its maximum density at approximately 4ºC, which is 1,000 g/cm3. Therefore, during times such as spring and fall, the water reaches temperatures near this and becomes denser than the rest, going to the bottom. This causes a vertical movement called the convection current, which is responsible for mixing the nutrients dissolved in water.
The higher-density liquid water shelters organisms from cold air better than the less-dense ice.

Answer/Explanation:
Let's say the allele for short hair is S and the allele for long hair is s. Since long hair is recessive, an individual would need to have two copies of that allele to show the genotype (h0m0zygous - ss). That means they must inherit one from each parent.
A guinea pig with short hair could be h0m0zygous (SS) or heterozygous (Ss)
Since a short haired male and a short haired female produced some long haired offspring, they must each have a copy of the long haired allele (s). Otherwise there is no way their offspring could inherit two copies of the s allele. The offspring must have got one s allele from each parent.
Therefore, the parents must both be heter0zygous (Ss)
