Biology Volume-6(Zoology-II)
Description: Darwin's theory of evolution proposes natural selection as the mechanism driving the gradual change and adaptation of species over time
Description: Industrial melanism is the adaptation of organisms to dark coloration in polluted environments, driven by natural selection for camouflage
Description: Convergent evolution: unrelated species evolve similar traits due to similar environmental pressures. Adaptive radiation: rapid diversification of species into different ecological niches.
Description: Common human diseases include cardiovascular diseases, respiratory infections, cancer, diabetes, and mental health disorders, impacting individuals worldwide across ages.
Description: Immunity is the body's defense system against pathogens, involving white blood cells, antibodies, and memory cells for long-term protection.
Description: Founder effect: genetic drift in small population founding a new colony, leading to reduced genetic diversity. Bottleneck effect: population drastically reduced.
Description: Organ grafting involves transplanting organs from a donor to a recipient to replace damaged or failing organs, often saving lives.
Description: Biotechnology uses biological systems, organisms, or their derivatives to develop products and technologies for various fields, including medicine and agriculture.
Description: Agricultural biotechnology applies genetic engineering and molecular biology to improve crop yield, resistance to pests, and nutritional content for agriculture.
Description: Biotechnology in medicine uses genetic engineering and bioprocessing to develop drugs, vaccines, and therapies for treating diseases and improving healthcare.
Description: PCR amplifies DNA segments in vitro. Genetic engineering manipulates DNA to create organisms with desired traits for various applications.
Description: Electrophoresis separates DNA fragments by size. Cloning vectors are DNA molecules used to carry foreign DNA into host cells for replication.
Description: The origin of life involves abiogenesis, where life arises from non-living matter, possibly through chemical evolution in primordial environments.
