Astrobiology

  The study of the origins, evolution, distribution and future of life in the universe is known as astrobiology .  Astrobiology, previously known as exobiology, is a multidisciplinary science that investigates the origins, early evolution, distribution, and future of life in the universe. Astrobiology is the study of whether or not alien life exists, and if so, how we can detect it .  This interdisciplinary field necessitates a thorough knowledge of biological, planetary, and cosmic events. The quest for habitable environments in our Solar System and on planets orbiting other stars, as well as the search for evidence of primordial chemistry or life, is all part of astrobiology. Searching for evidence of prebiotic chemistry or life on Solar System worlds such as Mars, Jupiter's moon Europa, and Saturn's moon Titan; and studying the origins, early evolution, and assortment of life on Earth.  Astrobiology combines molecular biology, biophysics, biochemistry, chemistry, ...

Heredity and Evolution

  Heredity is the transfer of biological characters from one generation to another via genes in simple words transfer of characteristics from parents to offspring is heredity. Johann Gregor Mendel is the pioneer of modern genetics.  Because of Hugo de Vries mutational theory, the cause of the abrupt alterations was discovered in 1901.  Living organisms, according to de Vries' mutation theory, can generate alterations to their DNA that drastically alter the organism. These alterations are handed down from generation to generation, resulting in the emergence of new species. To know the reasons behind the same characteristics and facial features check out my blog: https://bustlingmindd.blogspot.com/2021/05/dna.html When a new species evolves, it becomes stable and ceases to change.   The fact that both the father and the mother contribute nearly equal amounts of genetic material to the kid determines the rules for the inheritance of such qualities in humans. This indica...

Brain(Structure, Function, Parts and disorders)

  The brain is a three-pound organ that regulates all bodily processes, analyses information from the outside world, and embodies the mind and soul's essence. The brain controls many things, including intelligence, creativity, emotion, and memory. The brain of an adult human weighs about 1300-1400 grams and consists of approximately 100 billion neurons.  The cerebrum, cerebellum, and brainstem are the parts of the brain that are protected within the skull. The forebrain, midbrain, and hindbrain are the three main units that make up the brain. The top section of the spinal cord, the brain stem, and a wrinkled ball of tissue called the cerebellum make up the hindbrain. 1. Cerebrum : This is the largest part of our brain and consists of two cerebral hemispheres. The cerebrum is split into two hemispheres: left and right. The corpus callosum nerve fibers link the two sides. These hemispheres are joined with each other with the help of tough fibers. 2.  Cerebellum:  ...
