Sympathetic tone refers to the state of excitation of the sympathetic nervous system, which cannot be precisely measured and is constantly changing. Increased sympathetic tone puts the body into a type of response mode such as flight or attack. It is noticeable, among other things, by an increase in blood pressure, acceleration of the heart … Sympathetic Tone: Function, Task & Diseases
Crossing-over is the exchange of maternal and paternal chromosomes as it occurs during the prophase of meiosis. This piece exchange allows for the trait diversity of offspring. Errors in crossing-over cause diseases such as Wolf-Hirschhorn syndrome. What is crossing-over? Crossing-over is the exchange of maternal and paternal chromosomes that occurs during the prophase of meiosis. … Crossing Over: Function, Tasks, Role & Diseases
The induced-fit theory originated with Koshland and corresponds to an extension of the lock-and-key principle, which assumes that anatomical structures fit together. Induced-fit refers to enzymes such as kinase that change their conformation to form an enzyme-ligand complex. In enzyme defects, the induced-fit principle may be affected by perturbations. What is induced-fit? There is binding … Induced-fit: Function, Tasks, Role & Diseases
A short nap or daytime nap refreshes and makes you more efficient. While young children still take extended naps, daytime naps become less important as they grow older. It can even be harmful.

How hereditary diseases are inherited Every hereditary disease is inherited either monogenetically or polygenetically: this means that there is one or more gene locus that must be altered in order to cause a disease. Furthermore, genetic traits can always be inherited dominantly or recessively: Recessive means that there must be a predisposition for this particular … How hereditary diseases are inherited | Genetic diseases
Xeroderma Pigmentosum Xeroderma pigmentosum is a rare, hereditary disease in which certain enzymes in the skin of the affected individuals do not function. These enzymes normally repair the DNA, which can be damaged by sunlight or the UVB light it contains.

According to chronobiology, day people or so-called larks are genetically day-active early risers. Night people or so-called owls, on the other hand, are nocturnal and sleep longer in the morning. Those who live contrary to their biologically pre-programmed sleep-wake rhythm in the long term can develop daytime fatigue and even psychoses. What are day and … Day and Night People: Function, Task & Diseases
Hemoglobin synthesis is composed of heme synthesis and globin synthesis. Finally, the linkage of the prosthetic heme group with four globins each occurs to form the iron-containing protein complex hemoglobin. Both disorders in heme synthesis and globin synthesis can lead to serious health problems. What is hemoglobin synthesis? Hemoglobin is an iron-containing protein complex found … Hemoglobin Synthesis: Function, Role & Diseases
