Definition An ecological niche is defined as the role and position a given species plays in its environment; how it reproduces, survives,and acquire the need for food and shelter. Ecological niches include both biotic factors (living things) and abiotic factors (non-living things). Introduction. The uniqueness of an organism’s niche is of importance because it … Read more

  Birth control is the prevention of pregnancy before it can begin. It is also known as fertility control, or contraception. Since ancient times, many birth control methods have been controlled, but the safe and effective methods only become available in the 20th century.

  In many countries, the most notable group of diseases are sexually transmitted diseases. These diseases are more common in people who are 150-50 years old. Mainly, sexually transmitted diseases are infections and are spread by sexual contact. They can cause severe damage to the body, infertility, pregnancy complications, and may even lead to death. … Read more

  Natural selection is a term that is used to refer to the evolution, over a certain period in the species, in which the genes are responsible for their survival, and adaption. The idea of natural selection was proposed by Charles Darwin, who is the main researcher behind the modern concepts of evolution. In natural … Read more

  National parks are used for the conservation of biodiversity. Often, the national parks are the combination of developed, semi-natural and natural land that is owned by the sovereign state. The national parks are differently designated by the individual nations, but the idea of the national park is the same all over the globe, which … Read more

  Mutualism is an association, between the organisms of two different species, where they give benefit to each other. The mutualistic arrangements develop when the organisms are greatly different from each other according to their living conditions. Mutualistic interactions are beneficial for both of the interacting species. Mutualism is found to exist between the 200, … Read more

  Alleles are seen as an alternative form of a gene, and they are usually responsible for differences in the phenotypic expression of a particular trait e.g., brown eyes versus green eyes. A gene in which at least two alleles exist is referred to as polymorphic. In a situation in which a particular gene may … Read more

  Binary fission is the type of asexual reproduction, where, new bodies are formed by the separation of already existing bodies. In this process, the genetic material of the organism is duplicated and then by the cytokinesis, it is divided into two parts. One copy of the DNA is received by each new organism. In … Read more

  The modern synthetic theory is based on the genetic changes in the populations, which causes the formation of the new species. It also explains the Mendelian population or the genetic population, gene frequency, and the gene pool. The concepts which come under the synthetic theory of evolution are geographical and reproductive isolation, natural selection, … Read more

Wastewater can do serious damage to the surroundings if left untreated. That’s as a result of waste from humans and pets square measure supply of many kinds of waterborne diseases and microorganisms contamination. Thanks partly to microorganisms, treating wastewater and waste material is feasible. The role of microorganisms in effluent treatment helps to treat and … Read more
