Genetics is the study of genes, genetic variation, and heredity in organisms. [ 1][ 2][ 3] It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically.
The first model proposed is the limbic-cortical model, which involves hyperactivity of the ventral paralimbic regions and hypoactivity of frontal regulatory regions in emotional processing. [79] Another model, the cortico-striatal model, suggests that abnormalities of the prefrontal cortex in regulating striatal and subcortical structures ...

[ 1][ 2] Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of ...

Like the banana, the avocado is a climacteric fruit, which matures on the tree, but ripens off the tree. Avocados used in commerce are picked hard and green and kept in coolers at 3.3 to 5.6 °C (37.9 to 42.1 °F) until they reach their final destination. Avocados must be mature to ripen properly. Avocados that fall off the tree ripen on the ...
Frequency. 15% (50 year olds), 70% (over 80 year olds) [ 7 ] Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly. [ 3 ]
Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), [ 2] and contains proteins, glucose, mineral ions, and hormones. The blood cells are mainly red blood cells (erythrocytes), white blood cells (leukocytes), and (in mammals) platelets (thrombocytes). [ 3]
British undergraduate degree classification. The British undergraduate degree classification system is a grading structure used for undergraduate degrees or bachelor's degrees and integrated master's degrees in the United Kingdom. The system has been applied, sometimes with significant variation, in other countries and regions.
