Numerous scientific and technological advances were accomplished by the Ancient Greeks. Greek philosophers started to adopt new perspectives on the world. They developed hypotheses about how the universe operated and believed that the natural world adhered to a set of rules that could be observed and understood via research.
Pythagoras studied geometry. Pythagoras kept track of all the mathematical advancements that were accomplished in Greece over time. To determine the sides of a right triangle, he established the Pythagorean Theorem, which is still in use today.
Euclid was arguably the most significant Greek mathematician. Numerous works titled Elements were written by Euclid on the subject of geometry. For 2000 years, these texts served as the de facto reference on the subject. Sometimes referred to as the most influential textbook in history, Euclid's Elements.

The macromolecule must be starch.
Explanation:
Starch is a polymer of Glucose joined by glycosydic bond.
Starch is the main energy storage substance in green plants.
Starches react with iodine and give a bluish black or black color and thus iodine test is considered as a confirmatory test for starches.
In this experiment ,the solution turns very dark black on addition of iodine so we can be sure that the solution contained starch.

Answer:
The correct option is <em>B. Crossing- over </em>
Explanation:
In biology, crossing over can be described as a phenomenon by which homologous chromosomes exchange segments during the process of meiosis.
The unexpected results came because the DNA segment between the homologous chromosomes was exchanged during meiosis. The alleles got shuffled by this process and hence showed the unexpected results.
Crossing over and independent assortment are phenomenon which occurs only during the process of meiosis. These phenomenons cannot be observed during mitosis.
