Natural selection is the process by which individual organisms with favorable traits are more likely to survive and reproduce than those with unfavorable traits. In order for natural selection to occur there must be heritable variation for a trait and there must be differential survival and reproduction associated with that trait. (C.Stated) Heritable traits become either more or less common in population as the inherited traits in the differential reproductive success of the better adapted organisms

conservation of natural resources conservation of natural resources‚ the wise use of the earth’s resources by humanity. The term conservation came into use in the late 19th cent. and referred to the management‚ mainly for economic reasons‚ of such valuable natural resources as timber‚ fish‚ game‚ topsoil‚ pastureland‚ and minerals‚ and also to the preservation of forests‚ wildlife‚ parkland‚ wilderness‚ and watershed areas. In recent years the science of ecology has clarified the workings of the biosphere;

STATED CLEARLY: EVOLUTION AND NATURAL SELECTION (TRANSCRIPT) What exactly is evolution? In biology‚ the theory of evolution doesn’t exactly tell us how life began on Earth‚ but tells us how life‚ once it came into existence‚ diversified into the many incredible forms we see now and in the fossil record. It also helps us make sense of the way in which modern creatures continue to adapt and change today. In biology‚ evolution can be defined as: ‘Any change in the heritable traits (those are physical

Title: Background In Bangladesh‚ natural gas is one of the important sources of energy that accounts 75% of commercial energy of the country. Again‚ Bangladesh is important to world energy markets because of its large potential natural gas reserves. This resource really reduces importing fuel from other countries and saving large number of foreign currencies. All power‚ fertilizer and today the transport sector of Bangladesh are by no means dependent on Natural Gas. From the beginning of this century

statement about evolution is FALSE? 1. Natural selection is about slow but steady progress. Through it‚ populations constantly get better-adapted. When this process is completed for all populations‚ evolution will come to a stop. 2. According to evolutionary theory‚ you are related to a bacterium‚ to a yeast cell‚ to a snake‚ and to a whale. In fact‚ you are related to every species now alive on Earth‚ and to fossil species like dinosaurs as well. 3. Natural selection acts on genetic differences

There is a common misconception that evolution occurs randomly. This misunderstanding incorrectly assumes that natural selections itself is random. However‚ even though randomness plays a part in the process of evolution through genetic mutations‚ it does not necessarily stipulate that species evolve without cause. Genetic variation occurs randomly and is determined by the fitness and success of a species. It is directly related to its inherited traits with the context of its local environment. The
