The significance of the radioactive isotopes Hershey and Chase chose is that C. Phosphorus is abundant in DNA, while sulfur is abundant in proteins.
What is the relative importance of the experimental procedure by Hershey and Chase?The relative importance of the experimental procedure by Hershey and Chase is based on the fact that they found which of these biomolecules (i.e. DNA or proteins) represents the genetic material in the organisms which is inherited across generations in order to shape the phenotypic features of the species. This experiment is based on the use of radioactive isotopes that were incorporated into the biomolecules.
Therefore, with this data, we can see that the relative importance of the experimental procedure by Hershey and Chase is founded on the observation that DNA is the genetic material inherited across generations in order to shape traits.

How many atoms are in a mole of oxygen atoms?
The number of atoms in one mole of oxygen atoms is 1 mole of oxygen gas contains 6.02 × 1023 molecules of O2
One mole represents the amount of substance of a system that contains a number of elementary quantities (atoms, molecules and ions) equal to the number of atoms present in exactly 12 grams of the isotope Carbon 12.
To calculate the number of atoms, use the formula Avogadro's constant = 6.02 × 1023 particles. This means that one mole of any substance will have the same number of particles, which is equal to 6.02 × 1023 particles. Then the number of atoms in one mole of oxygen atoms is 1 mole of oxygen gas contains 6.02 × 1023 molecules of O2.

Crossing over is the mechanism that occurs during meiosis in order to produce and maintain genetic variation in natural populations.
Crossing over is the event that takes place in the pachytene stage of the Prophase I of meiotic cell division. It is the process where the exchange of the genetic material takes place between the two non-sister chromatids of the homologous chromosomes.
Meiosis is the type of cell division that results in the formation of daughter cells from one single parent cell. The number of chromosomes are halved in the daughter cells and therefore it is named as the reductional division. Meiosis can be accomplishes in two parts: meiosis I and meiosis II.

What are the types of natural selection in biology?
The types of natural selection in biology are: Stabilizing selection, Directional selection, Disruptive selection, and Sexual selection.
Natural selection is the process by which certain traits become more or less common in a population over time, based on how well those traits enable the individuals who possess them to survive and reproduce.
1. Stabilizing selection: This occurs when traits that fall within a certain range are favored, while those that deviate from that range are selected against. This leads to the stabilization of a trait within a population.
2. Directional selection: This occurs when a certain trait becomes more or less favorable, causing the population to shift in that direction. This leads to a change in the average value of a trait within a population.
3. Disruptive selection: This occurs when traits at both extremes of a range are favored over those in the middle. This can lead to the splitting of a population into two distinct subpopulations, each with their own favored trait.
4. Sexual selection: This occurs when certain traits are favored because they increase an individual's ability to attract a mate. This type of selection can lead to the evolution of exaggerated or flashy traits, like the colorful plumage of a peacock.
