Starting from definition, pleiotropy is seen as a situation in which one gene controls for the expression of multiple phenotypic traits. These traits do not have to be clearly linked, i.e., eye color and eye shape, but can rather be completely unrelated. In many situations, this multi-trait impact is because of a gene code … Read more
Surface Chemistry: Brownian movement One of the first pieces of evidence for how gases move was discovered by Robert Brown a botanist who noticed that pollen grains in the water moved about randomly. Robert Brown noticed that small grains of pollen (Clarkia) suspended in water, moved in a haphazard or random fashion. In 1905, Einstein … Read more
Viewing plant breeding from the agricultural perspective, it makes use of principles from a variety of sciences to improve the genetic potential of plants. And this particular process involves combining parental plants to reproduce the next generation with the best characteristics. Breeders are improving plants by choosing those with the greatest potential based on … Read more
Introduction Patterns do exist at various scales in time and space. Patterns range from population abundances through ecosystems, communities, biomes, and the whole biosphere. Ecology is still ambivalent about pattern-seeking regardless of the many years of research, which is a curious fact in itself. Ecological scientists are yet to collect significant data about patterns … Read more
Studies have shown reasons for vary in biodiversity pattern across the globe. Biodiversity is not evenly distributed, and it varies greatly across the universe as well as within regions. other factors are, the diversity of all living things “biota” depends on soil, temperature, altitude, appreciation, geography and the presence of other species. And the … Read more
Parturition means childbirth. Childbirth is the culmination of pregnancy, during which a baby grows inside a woman’s uterus. Childbirth is also called labor. Pregnant women go into labor mostly after nine months of conception. Dilation The first stage of parturition begins when the labor starts. It continues until the cervix is fully dilated. This … Read more
Parthenocarpy is seen in plants as a relatively unusual condition which does occur in some of the common fruit. This circumstance occurs when the ovary of a flower develops into a fruit without any fertilization. It resulted in a seedless fruit. Now, what is Parthenocarpy? The word ‘Parthenocarpy’ comes from the Greek word meaning … Read more
Surface Chemistry: Tyndall effect A beam of sunlight is not visible to the naked eye unless the light passes through particles of water (mist) or dust in the air. These particles are responsible to scatter the sunlight and show its direction of penetration. Similarly, the light becomes is visible as it passes through a colloid. … Read more
Parasitism is the type of population interaction, in which one organism lives inside or on the body of another organism, for getting the nutrition for its survival. The organism, which serves the other one is the host, and the organism which gets the food is the parasite. The host is larger, and generally, the … Read more
Ozone layer depletion is characterised by the large, seasonal, decrease in stratospheric ozone over Earth’s polar regions and a slow decline of four per cent in the total volume of Ozone in Earth’s ozone layer since the ’70s. A balance between the photochemical production and recombination determines the overall amount of the Ozone in the … Read more
