Introduction: Mutation, recombination during gamete development, and environmental variables all cause variations. Genetic variation leads to differences in alleles, therefore, having different genotypes. To understand the process of variations within a population, let’s dive into this article. Genotypic variance: Changes in the chromosome or genes and different alleles of the same gene generate a genotypic…
Introduction: STIs, or sextually transmitted infections occur when an infected person passes their body fluids on to a healthy person. This level of intimacy usually occurs during sex – thus the name! STIs are often caused by bacteria or viruses. This guide explores common infections caused by these pathogens, and resulting STD symptoms. Bacterial STIs…
Introduction: Although the potential to procreate and recuperate may have been lost before this time, the death of the last individual of the species is typically regarded as the moment of extinction. There are different types of extinctions with various causes. Let’s learn the impact of extinction and what causes it. Effects of extinction: When…
Introduction: The human body is a complex and minutely organized structure of unique cells, all working together to accomplish specific functions required for sustaining life. Proteins, vitamins, and minerals are essential nutrients necessary for the nourishment, maintenance, and functioning of the human body. Hormones in the body regulate the balanced functioning of various organs, including…
Introduction Protists are unicellular eukaryotic organisms and they are grouped in a separate kingdom named ‘Protista.’ Protists are primarily aquatic organisms present in marine or freshwater environments. They are also present on damp terrestrial areas, decaying leaves, etc. They are autotrophic, heterotrophic, or both, and they reproduce asexually and sexually. Usually, harmful protists are animal-like…
Introduction: The cnidarians are part of the animal kingdom, and examples are jellyfish, corals, sea anemones, and hydrozoans. The species can be found throughout the world and are quite diverse. When the cnidarian gets damaged, these can regenerate their body parts, making them immortal. Facts about cnidarian Even though the scientific name is ‘Cnidaria’, they…
Plant Evolution Like any other living being, plants also undergo a series of evolutionary steps. Over time they adapted, changed, and became what we see today. The evolutionary history of plants has been preserved in fossils. These fossils date back to some 400-500 million years back. It is believed that the evolutionary development of the…
Plant Classification The classification of plants is based on their evolutionary and genetic relationship. Plant taxonomy is a branch of science that keeps changing because new species are found each day! Plant classification is done in various ways. High-level classifications include vascular and nonvascular plants. The plant categories like vascular plants are further categorized into…
Plant Growth Growth is regarded as one of the most fundamental characteristics of a living being. It can be defined as a permanent and irreversible rise in the sizes of one or all of its parts. Metabolic processes follow growth. For example, the enlargement of a leaf is called growth. What is Growth and Development…
Comparitive Anatomy Scientists always try to find more and more evolutionary relationships between species. But why do they do that? They are in search of a common ancestor, of course. Scientists have come so far by understanding the concept of evolution that organisms undergo for their survival. You must’ve seen animals with the same body…
