Abiogenesis: Early theory that held that some organisms originated from nonliving material.

Abnormal hemoglobin: Hemoglobin molecule with a different shape due to an altered amino acid sequence (ultimately caused by an altered DNA base sequence), such as in the inherited disease sickle-cell anemia.

Abscisic acid: A plant hormone that promotes dormancy in perennial plants and causes rapid closure of leaf stomata when a leaf begins to wilt.

Absolute time: One of the two types of geologic time (relative time being the other), with a definite age date established mostly by the decay of radioactive elements, although ages may also be obtained by counting tree rings, decay of a specific type of atom, or annual sedimentary layers (such as varves in lakes or layers in a glacier). The term is in some disfavor because it suggests an exactness that may not be possible to obtain.

Absorption: The process by which the products of digestion are transferred into the body's internal environment, enabling them to reach the cells.

Absorptive feeders: Animals such as tapeworms that ingest food through the body wall.

Acetylcholine: A chemical released at neuromuscular junctions that binds to receptors on the surface of the plasma membrane of muscle cells, causing an electrical impulse to be transmitted. The impulse ultimately leads to muscle contraction.

Acetyl CoA: An intermediate compound formed during the breakdown of glucose by adding a two-carbon fragment to a carrier molecule (Coenzyme A or CoA).

Acid: A substance that increases the number of hydrogen ions in a solution.

Acid rain: The precipitation of sulfuric acid and other acids as rain. The acids form when sulfur dioxide and nitrogen oxides released during the combustion of fossil fuels combine with water and oxygen in the atmosphere.

Acoelomates: Animals that do not have a coelom or body cavity; e.g., sponges and flatworms.

Acquired immunodeficiency syndrome (AIDS): A collection of disorders that develop as a result of infection by the human immunodeficiency virus (HIV), which attacks helper T cells, crippling the immune system and greatly reducing the body's ability to fight infection; results in premature death brought about by various diseases that overwhelm the compromised immune system.



Actin: The protein from which microfilaments are composed; forms the contractile filaments of sarcomeres in muscle cells.

Action potential: A reversal of the electrical potential in the plasma membrane of a neuron that occurs when a nerve cell is stimulated; caused by rapid changes in membrane permeability to sodium and potassium.

Active transport: Transport of molecules against a concentration gradient (from regions of low concentration to regions of high concentration) with the aid of proteins in the cell membrane and energy from ATP.



Adaptation: Tendency of an organism to suit its environment; one of the major points of Charles Darwin's theory of evolution by natural selection: organisms adapt to their environment.

Evolutionary pattern of divergence of a great many taxa from a common ancestral species as a result of novel adaptations or a recent mass extinction. Examples: mammals during the Cenozoic Era after the extinction of dinosaurs at the close of the Mesozoic Era flowering plants during the Cretaceous Period diversified because of their reproductive advantages over gymnosperm and non-seed plants that dominated the floras of the world at that time.

Amoebocytes: Amoeboid cells in sponges that occur in the matrix between the epidermal and collar cells. They transport nutrients.

Amphibians: Class of terrestrial vertebrates which lay their eggs (and also mate) in water but live on land as adults following a juvenile stage where they live in water and breathe through gills. Amphibians were the first group of land vertebrates; today they are mostly restricted to moist habitats.

MUSLIM SCIENTISTS WITH THEIR WORK

Thursday, 13 March 2014

Definition:
Science can be defined as study
"mainly concerned with the phenomenan of physical universe any or all of natural sciences or biological sciences."
or
Science as the "the field of study which attempts to describe and understand the nature of the universe in whole or part."

Science is the faculty to reason out the how and why of the things as they occur in the phenomenal world or the objective world..Basically science is the study of laws of nature and man has developed science by observing.Infact this subject has completely transformed our power over nature and the world outlook.Development of the modern technology is directly the outcome of the development of modern science.Without the scientific revolution the industrial revolution would not have been possible.

It has raised the human activity level by signifiacnt observations in the various fields of human existence.Whether its the exploration of human health,industrial progress,agrarian developments and modern communication technologies,the benefits gained from this major subject are enormous.Infact it would not be wrong to say that we are living in the age of science and is a dominant factor in our day to day existence.
