Answer:
A. dihybrid crosses
Explanation:
A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.
Answer:
The presence of similar <u>fossils(B)</u><u> </u> and <u>rock formations(C)</u> on several different continents supports the theory of Continental Drift.
Explanation:
Alfred Wegener observed fossils of organisms that were not supposed to have survived in the climate of where they were found. Other key findings is that he found fossils of organisms that were found in one continent and the same fossils found on another continent whose edges seem to fit together.
He also observed rock formations or stratas of mountain ranges in one continent seem to fit together with another continent.
<u>Added note:</u>
Even if Alfred Wegener had these evidences to present, his theory of Continental Drift was rejected mainly because he could not explain the mechanism of how the super continent (Pangaea) split.

Genetics is the study of genes.
Answer:
As the yeast eats the sugar, it releases a gas called carbon dioxide. The gas fills the bottle and then fills the balloon as more gas is created. Each bit of yeast makes tiny gas bubbles and that puts millions of bubbles (holes) in our bread before it gets baked.
