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.

Fragments of copied DNA created on the lagging strand are true. Because on the lagging strand short DNA fragments are formed.

Lagging stands are slow stands where that are used to extend DNA strands or to grow Okazaki fragments. Lagging stands are synthesized discontinuously by DNA polymerase.

Okazaki fragments are short DNA fragments (sections) in the DNA replication process in the slow DNA strands.

Meanwhile, the leading strand is the guard strand of DNA which is synthesized in the 5`-3` direction continuously and very quickly.

The lagging strand starts replication opposite to the replication process that occurs in the leading strand, namely from 3' to 5'. This process begins with the steps of the primase enzyme which forms a new part called the RNA primer. This process takes place continuously but in the primary formation, it is broken into certain parts.

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.

Demetrius's results suggest that digestive enzymes are crucial to maintaining homeostasis in the body by breaking down large molecules of food into smaller, more easily absorbed molecules.

Digestive enzymes are produced by different organs of the digestive system such as the salivary glands, stomach, pancreas and small intestine. These enzymes work together to break down food into smaller molecules that can be absorbed and utilized by the body's cells.

Homeostasis is the maintenance of a stable internal environment in the body. The body needs to maintain the correct balance of nutrients, electrolytes, and other substances in order to function properly. Digestive enzymes are essential for maintaining this balance by breaking down food into the correct molecules that can be used by the body.

Moreover, Digestive enzymes also play a key role in the regulation of blood sugar levels, by breaking down carbohydrates into glucose, which can be used as an energy source by the body, preventing fluctuations in blood sugar levels and avoiding conditions such as diabetes.
