Monocot & Dicot Seeds Flowering plants generally referred to as angiosperms, fall into two classes, based on the number of cotyledons or seed leaves, within their seeds. For monocotyledons, also referred to as monocots, seeds contain only one cotyledon and when a monocot seed germinates, it produces a single. It is usually long and narrow, … Read more
The intestines are a long, continuous tube running from the stomach to the anus. Most absorption of nutrients and water happen in the intestines. The intestines include the small intestine, large intestine and rectum. What Is Small Intestine? The small intestine also referred to as small bowel, is an organ in the gastrointestinal tract where … Read more
What Are R-Selected Species? R-selected species, also referred to as r-strategist, are species whose populations are determined by their maximum reproductive capacity (biotic potential). R-selected species thrive in unstable habitats such as freshly burned grasslands, vernal ponds, carrion or forests characterized by canopies that open abruptly such as when a forest’s tallest tree has been … Read more
What A Is Food Chain? A food chain is a descriptive diagram including a series of arrows, each pointing from one species to another, representing the flow of food energy from one feeding group of organisms to another. There are two types of food chains, they include: Grazing food chain Detritus food chain The grazing … Read more
When it comes to digital electronics and sequential logic circuits, counters play an important role in a number of applications. They serve as indispensable components for tasks such as counting, frequency division, and synchronization. Among the various counter types available, two prominent contenders often stand out: the Ring Counter and the Johnson Counter. Both of … Read more
Generally, a flower is the reproductive organ of flowering plants, containing sepals, petals, pistils and stamens. Based on the position of calyx, corolla and androecium in respect of the ovary on thalamus (receptacle), the flowers can be described as Hypogenous, Perigynous or Epigynous. What Is A Hypogenous Flower? Hypogenous flower is a flower in which … Read more
In evolutionary science, classification of living organisms is critical in understanding life’s history of group of organisms. For a very long time, scientists and researchers have tried in very many ways to represent these complex relationships in a visually informative manner and in all their trials, two methods have always emerged as the best . … Read more
What Is A Light Microscope? Microscopes are very important tools for scientists; they are used in microbiology, material science, mineralogy and medicine. A light microscope can simply be defined as, an instrument that uses visible light and magnifying lenses to examine small objects not visible to the naked eye or in finer detail than the … Read more
An inotrope is agent that alters the force or energy of muscular contractions. There are two categories of inotrope that is negatively inotropic agents and positively inotropic agents. Positively inotropic agents such as dopamine, Epinephrine, Isoproterenol, Amiodarone, etc. increase the strength of muscular contraction while negatively inotropic agents such as labetol and propanolol weakens the … Read more
What Is Osmotic Potential? Osmosis takes place across water potential gradient i.e water moves from a region of high water potential to a region of low water potential. Water potential is the measure of concentration of free water molecules (the ones that are free to move) in other words, the potential energy. Water potential of … Read more
