The phenotype is the outwardly visible appearance of an organism with its various characteristics. Both genetic makeup (genotype) and environment influence the expression of the phenotype. What is the phenotype? The phenotype is the outwardly visible appearance of an organism with its various characteristics. The visible expressions of an organism, but also the behavior and … Phenotype: Function, Tasks, Role & Diseases
Phenotypic variation describes different trait expressions of individuals with the same genotype. The principle was popularized by the evolutionary biologist Darwin. Diseases such as sickle cell anemia are based on phenotypic variation and were originally associated with an evolutionary advantage. What is phenotypic variation? By phenotypic variation, biology refers to the different trait expressions between … Phenotypic Variation: Function, Role & Diseases
The appearance of an organism is called its phenotype. In this context, the phenotype is shaped both genetically and by the environment. Natural phenotypic changes in an organism are usually caused by environmental factors. What is phenotypic change? Natural phenotypic changes to an organism are usually caused by environmental factors. Phenotypic changes can occur in … Phenotypic Changes: Function, Task & Diseases
Amelogenesis is the formation of tooth enamel, which is carried out in two phases by ameloblasts. A secreting phase is followed by a mineralizing phase that hardens the enamel. Enamel formation disorders make teeth more susceptible to decay and inflammation and are often treated with crowning. What is amelogenesis? Amelogenesis is the formation of tooth … Amelogenesis: Function, Tasks, Role & Diseases
Nuclear division (mitosis) of cells of eukaryotic organisms with replication of DNA can be divided into four main phases. The second main phase is called metaphase, during which chromosomes contract in a spiral pattern and position themselves in the equatorial plane at approximately equal distances from both opposite poles. The spindle fibers, starting from both … Metaphase: Function, Tasks, Role & Diseases
Callus hardening is the fourth phase of the five-phase secondary fracture healing process. Osteoblasts form a callus of connective tissue to bridge fracture gaps, which they mineralize with calcium to harden it. In fracture healing disorders, this process is impaired and the bone lacks stability. What is callus hardening? Callus hardening is the fourth phase … Callus Hardening: Function, Tasks, Role & Diseases
Chewing creates swallowable bites and is much more than reducing the size of food in the mouth. It is the first step in the digestive process and is critical for healthy teeth and an intact gut. What is chewing? Chewing creates swallowable bites and is much more than reducing food in the mouth. It is … Chewing: Function, Task & Diseases
Skin aging is a very complex biological process that varies greatly from person to person. It is usually of cosmetic interest only, but can also be an indicator of pathological processes in the body. Aging of the skin is influenced by both external (environment) and internal factors (genetics). What is skin aging? Skin aging occurs … Skin Aging: Function, Tasks, Role & Diseases
The term palmar flexion is used on the human body exclusively for a movement of the hand. It is involved in many everyday and athletic movements. What is palmar flexion? Palmar flexion is a flexion that is in the direction of the palm. It involves the palm of the hand approaching the forearm. Like its … Palmar Flexion: Function, Tasks, Role & Diseases
Digestion is the elementary process for every human being, which begins with food intake and ends with defecation. In between, food is broken down to obtain energy and substances important for cells. Digestive disorders range from heartburn and stomach pain to diarrhea and vomiting and should always be taken seriously. What is digestion? The chemical … Digestion: Function, Tasks, Role & Diseases
The threshold potential describes a specific charge difference at the membrane of excitable cells. When the membrane potential attenuates to a certain value in the course of depolarization, an action potential is induced via the opening of voltage-dependent ion channels. The value to be reached in each case, which is necessary for the generation of … Threshold Potential: Function, Tasks, Role & Diseases
