A magnetic monopole is an isolated pole of a magnet that serves as an elementary particle in the field of Particle Physics. It can be either a single North or a single South Pole with a net magnetic charge on it. Its existence is purely hypothetical as according to the magnetic theory, even the smallest part of a magnet comes with two poles, north and south. Still a monopole is essential for defining certain physical quantities and doing calculations in the fields of electromagnetism and magnetism....

What is a Neutron A neutron is an uncharged sub-atomic particle found in all atomic nuclei and has a mass similar to a proton. A neutron is thus one of the three particles that constitute an atom. The other two being proton and electron. The common symbol of the neutron is n or n 0 . Neutrons are used in nuclear reactors where it helps to continue the process of nuclear chain reaction....

Nitrogen is the most abundant element in nature that is essential for plant growth and reproduction. It forms a significant component of chlorophyll, the pigment needed for photosynthesis. It is also found in ATP, nucleic acids, and amino acids, the building blocks of proteins. Although found abundantly, plants can only utilize reduced nitrogen from the soil. Nitrogen Fixation What is Nitrogen Fixation Atmospheric nitrogen fixation or only nitrogen fixation is when atmospheric nitrogen (N 2 ) is converted to ammonia (NH 3 )....

The nuclear envelope, also called the nuclear membrane, is the outer covering of the nucleus in eukaryotic cells. It is a double-layered barrier that separates the contents of the nucleus from the cytoplasm in both plants and animal cells. It also protects the genetic material of the cell, the DNA. If the nucleus is a city hall, the nuclear membrane is like the security fence around it. Among other organelles such as the endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, and the plasma membrane, the nuclear envelope is part of the endomembrane system, involved in the selective transport of molecules within the cell and also with the external environment....

What is the Life Cycle of a Plant Plants are living things that grow and reproduce, similar to all other living organisms on earth. The plant life cycle describes the stages that the plant goes through from its birth until its death. They are found in all types of plants; flowering or non-flowering and vascular or nonvascular. In flowering plants, the process starts with seed formation, which then germinates to give rise to a new plant....

All living organisms can be classified into three basic types of body symmetry. They are radial, bilateral, and asymmetrical. In this article, we shall discuss radial symmetry in detail. What is Radial Symmetry Radial symmetry is the type of body plan where an organism can be divided into many equal parts from a common center point, the central axis . The planes dividing the body are called the planes of symmetry ....

How is the pressure held constant in Rankine cycle when heat is added or rejected?

What is Amoeba Amoeba is an aquatic, single-cell (unicellular) organism with membrane-bound (eukaryotic) organelles that has no definite shape. It is capable of movement. When seen under a microscope, the cell looks like a tiny blob of colorless jelly with a dark speck inside it. Some parasitic amoebae living inside animal bodies, including humans, can cause various intestinal disorders such as diarrhea, ulcers, and liver abscesses. Entamoeba histolytica is an example of such amoeba that causes a disease called amoebic dysentery or amebiasis in humans....

The biosphere is where living organisms are found on, above, and below the Earth’s surface. It is thus one large ecosystem characterized by biotic (living things), abiotic (non-living) factors, and energy working together as a single unit. Since the biosphere supports life on Earth, it distinguishes our planet from other planets in the solar system. Several life forms are found to exist on Earth, from single-celled microorganisms to large, multicellular animals....

What is Chloroplast The chloroplast is a type of cell organelle called plastids found in plants and blue-green algae. It contains the pigment chlorophyll that traps the light energy of the sun to convert them to the chemical energy of food by a process called photosynthesis. The word ‘chloroplast’ is derived from the Greek words ‘chloros’, which means ‘green,’ and ‘plastes’, meaning ‘the one who forms’. Hugo von Mohl first discovered chloroplast in 1837, while Eduard Strasburger, in 1884, adopted the term ‘chloroplasts’....

What is Diffraction? Diffraction is the bending or spreading of light waves around an obstacle. The obstacle can be an aperture or slit whose size is approximately the same as the wavelength of light. The amount of bending depends on the relative size of the opening compared to the wavelength of light. The bending will be almost unnoticeable if the opening is much larger than the wavelength. Due to diffraction, the direction of waves changes as they pass around an obstacle in their path....

An electric field is an invisible force field caused by an electric charge resulting in an alteration of space (air or vacuum) around the charge. A magnetic field is an invisible force field generated by a moving electric charge (current), spinning electrons, and magnets. How are Magnetic and Electric Fields Similar Both electric field and magnetic field are two aspects of the same concept. Both are components of an electromagnetic wave moving perpendicular to each other....

Gluons, along with quarks, are the building blocks of protons and neutrons, which are, in turn, the building blocks of atomic nuclei. Just like photons transmit electromagnetic force between two charged particles, gluons are the exchange particles between quarks. So, they are responsible for binding protons and neutrons together in atomic nuclei. They are fundamental particles and thus cannot be broken down into smaller ones. They are named gluons because these particles function as the ‘glue’ that holds the nucleus and its constituent baryons together....

‘Hetero’ means other, and ‘trophe’ means ‘nourishment. A heterotroph is an organism that depends on other organisms for food and energy. These other organisms are known as autotrophs (primary producers). Unlike autotrophs, they cannot prepare their food from inorganic molecules. Thus, heterotrophs are also called consumers. Heterotroph All members of kingdom Animalia are heterotrophs, including dogs, cats, squirrels, rabbits, mice, lions, and leopards. Some plants, such as Venus flytrap and pitcher plants, are also heterotrophs as they feed on insects for their food....

The lifecycle accomplished by the virulent phages for their reproduction is called the lytic cycle. During the lytic cycle, the virus takes total control over the cell, reproduces new phages, and then destroys the infected cell and its membrane, releasing the virus particles. Here, the viral DNA exists as a separate entity within the host cell and replicates separately, which is its main difference from the lysogenic cycle. T4 bacteriophage is an example of a lytic phage infecting the bacterium E....

Plant tissues are of two main types: meristematic tissue and permanent tissue. Meristematic tissue is like stem cells in animals that have the potential to divide throughout life, thus contributing to plant growth. They are found in the stem and root meristems. Types of Plant Tissue Types of Meristematic Tissue Meristematic tissues are of three types, based on their location in plants. They are: 1. Apical Meristems They are found at the tips of roots and stems, enabling a plant to extend in length....

What is a Simple Leaf A leaf that has a single, undivided lamina is called a simple leaf. Unlike a compound leaf, the lamina of a simple leaf never gets divided into smaller leaflets. Characteristics A simple leaf shows the following characteristics: Directly attached to a twig by its stem or the petiole. Lateral buds are present at the base of the petiole. Margins or edges can be smooth, jagged, lobed, or parted....
