    The science which studies the progress of the human race through the laws of heredity is called [C] Eugenics. Eugenics is a controversial branch of science that seeks to improve the genetic quality of the human population by promoting selective breeding and controlled reproduction. It aims to increase desirable heritable traits and decrease undesirable ones, based on principles of genetics and inheritance. Eugenicists advocate for policies and practices such as sterilization of individuals deemed “unfit” or “undesirable,” encouragement of reproduction among those considered genetically superior, and restriction of reproduction among certain groups.

    However, eugenics has historically been associated with unethical and discriminatory practices, including forced sterilization and racial hygiene programs. Despite its discredited history, some aspects of eugenics still influence discussions about genetics, reproductive technologies, and public health policies today, highlighting the ongoing ethical and social implications of studying human heredity and genetic improvement.

    The branch of zoology that studies ductless glands is called [B] Endocrinology. Endocrinology is a specialized field of biology that focuses on the study of hormones, their production, secretion, and effects on the body. It encompasses the endocrine system, which includes ductless glands such as the thyroid, adrenal, pituitary, and pancreas. Endocrinologists investigate how hormones regulate various physiological processes, including metabolism, growth, reproduction, and stress responses. They explore hormone interactions with target cells, tissues, and organs, as well as their roles in maintaining homeostasis and coordinating bodily functions.

    Endocrinology plays a crucial role in understanding and treating endocrine disorders, such as diabetes, thyroid disorders, and hormonal imbalances. By studying endocrinology, researchers aim to advance knowledge of hormone biology, develop new treatments for endocrine-related diseases, and improve human health and well-being.

    Improving the race by improving the human environment is called [B] Euthenics. Euthenics focuses on enhancing human well-being by improving environmental factors such as education, nutrition, housing, sanitation, and social conditions. It aims to create a conducive environment that fosters physical health, mental well-being, and overall societal progress. Unlike eugenics, which emphasizes genetic selection and manipulation to improve the genetic composition of the human population, euthenics addresses societal and environmental factors that contribute to human development and quality of life.

    Euthenics promotes interventions at the community and societal levels to create healthier and more equitable living conditions for all individuals, aiming to uplift populations and foster collective advancement. By improving the human environment through education, infrastructure development, healthcare access, and social policies, euthenics seeks to enhance human potential and create a more thriving and inclusive society for future generations.

    The study of the rules of inheritance is called [C] Genetics. Genetics is a branch of biology concerned with the study of genes, heredity, and genetic variation in organisms. It examines how traits are passed from parents to offspring through the transmission of genetic information encoded in DNA molecules. Geneticists investigate the mechanisms of inheritance, including Mendelian genetics, molecular genetics, and population genetics, to understand how genes are expressed and regulated within organisms and populations. By studying genetics, researchers gain insights into the genetic basis of traits, diseases, and behaviors, as well as the evolutionary processes shaping genetic diversity over time.

    Genetics plays a crucial role in various fields, including medicine, agriculture, biotechnology, and conservation biology, contributing to advances in personalized medicine, crop improvement, genetic engineering, and biodiversity conservation. Overall, genetics provides fundamental knowledge about the principles governing inheritance, driving advancements in science and technology.

    The study of the shells of animals of the Mollusca community is called [D] Malacology. Malacology is a specialized branch of zoology that focuses on the scientific study of mollusks, including their anatomy, physiology, behavior, ecology, evolution, and classification. It particularly emphasizes the examination and analysis of mollusk shells, encompassing their structure, composition, growth patterns, and functional adaptations. Malacologists investigate various aspects of mollusk shells, such as their role in protection, locomotion, camouflage, and buoyancy, as well as their significance in environmental monitoring, paleontology, and biogeography. Through field surveys, laboratory experiments, and museum collections, malacologists contribute to our understanding of mollusk diversity, distribution, and conservation, providing valuable insights into the ecological roles and environmental interactions of mollusks. Malacology plays a crucial role in biodiversity research, ecosystem management, and the preservation of marine and freshwater habitats inhabited by mollusks.
