Answer:
Independent assortment
Explanation:
The law of independent assortment says that genes for different traits or characteristics assort independently from each other during gamete formation. So each contrasting character's pair assort independently and do not show any association with the pair of other characters.
So after gamete formation collectively the gametes have all the possible combinations of alleles because all the genes are assorted independently in gametes.
This independent assortment of traits leads to some new combination of characteristics in the offspring. Therefore the correct answer is independent assortment.
Answer: The heating process and the freezing process
Explanation:
When ice is heated up and begins to melt, the matter that makes up the ice (water) is infused with energy. The energy causes the ice to melt into a liquid and then into a gas. As the energy becomes greater and faster, the heat is more effective on melting/evaporating the ice/water.
When water is put in the freezer to chill, the cold air causes the energy cells to slow down, causing air to condense into water, and water to freeze into ice.
These are some examples that are easier to understand than other concepts, but there are many more of these occurrences in the world!
