Thermal conduction is the flow of thermal energy (heat) from higher to lower temperatures through molecular vibrations and collisions. Conduction occurs within an object or from a hot object to a cold object in contact with the former. It can occur in solids, liquids, and gases but is primarily observed in solids where molecules are closely packed. Heat will continue to flow until thermal equilibrium is reached. Conduction Examples Warming hands by touching a hot body Heating one end of a metal rod Heating a frying pan on top of a stove Hot air immediately above the Earth’s surface How is Heat Transferred Through Thermal Conduction...

What is Cytolysis The word cytolysis comes from the Greek word ‘kytos’ meaning ‘a hollow cell’ and ‘lysis’ that stand for ‘loosening’. So, cytolysis translates to the loosening of a hollow cell’. Cytolysis, also known as osmotic lysis, is defined as the breakdown or destruction of cells due to excessive influx of water into the cell. Cytolysis What Causes It It occurs when the capacity of the plasma membrane to hold the fluid exceeds its normal level....

A food chain shows a single feeding pattern between a predator and a prey in an ecosystem. However, in reality, the relationship between them is much more complex. An organism can have multiple food sources (prey) and simultaneously be eaten by multiple predators. Such a relationship is represented pictorially using a food web. It consists of all the interconnected and overlapping food chains in an ecosystem. Each living organism is part of multiple food chains that shows a possible path that energy and nutrients follow as they move through the ecosystem....

Grasshoppers are insects most commonly seen in autumn that can fly and leap. They belong to the order Orthoptera and suborder Caelifera. Around 11,000 species of grasshoppers in different colors are found to exist today worldwide; most of them are herbivores. They vary in size, although an adult grasshopper is about 1 to 7 cm in length. Stages of Grasshopper Life Cycle Grasshoppers, like the dragonfly, only have 3 stages in their lifecycle....

How do I get my energy Calculating for electricity

Your explanation is just WRONG. Please understand Newton’s Third Law before spewing your ignorance around, confusing others, because they take you as an authority: “…It applies a force due to its weight. According to Newton’s third law of motion, the surface responds by applying an equal and opposite force on the object. ” No! In your example, Newton’s 3rd law refers to the earth gravitationally attracting the object (action) and the object gravitationally attracting the earch (reaction)....

The photoelectric effect refers to the phenomenon where light, typically in the form of photons, can cause the emission of electrons from a material’s surface. In simple terms, when light shines on a material, it can transfer its energy to electrons within the material. If this energy is sufficient, the electrons can overcome the attractive forces holding them to the material and eject as free particles. These emitted electrons are referred to as photoelectrons....

What is a Refracting Telescope? Many scientific telescopes today use lenses to collect more light than the human eye could collect on its own. Their role is to focus the light and make distant objects appear brighter, more transparent, and magnified. A refracting telescope, or a refractor, uses a combination of lenses to produce images of distant objects, e.g., stars and planets that would otherwise not be visible with the human eye....

A volcano is an opening on the earth’s surface through which molten rocks, lava, volcanic ash, debris, and gases from the magma chamber reach the earth’s surface. Earth’s crust is broken into 17 major tectonic plates, which float on its mantle (the layer beneath the earth’s surface). Since these plates are always converging or diverging, sometimes they collide or pull apart, and volcanoes may erupt in these active zones. During a volcanic eruption, molten rock or lava come out through vents in Earth’s crust....

Have you ever wondered how electricity travels safely from power plants to your home or how your phone charger changes the voltage from the wall outlet to a safe level for your phone? Transformers are electrical devices that make it possible to transport and safely use electricity efficiently. They transfer energy between circuits using a principle called electromagnetic induction, which involves electricity flowing through a magnetic field to change the voltage....

Consider an electric field generated by a positive point charge. The direction of the electric field is such that it is radially outwards. When a positive test charge is brought closer to the point charge, it will experience repulsion due to electrostatic or Coulomb force. Energy is needed to overcome the repulsive force and move the test charge closer to the point charge, which is a source charge. This energy is known as electric potential energy....

Gluconeogenesis is the metabolic pathway in which glucose is produced from non-hexose precursors like glycerol, lactate, pyruvate, and some amino acids. It is a ubiquitous, anabolic process found in plants, animals, fungi, bacteria, and other microorganisms. In animals, including humans, gluconeogenesis occurs in the liver and, to some extent, in the cortex of the kidney. It is one of two primary mechanisms, along with glycogenolysis, used to maintain a proper glucose level in our blood....

An integral or intrinsic protein is a membrane protein found permanently embedded in biological membranes. For a protein to be an integral membrane protein, it would have to be amphipathic, with at least one hydrophobic region. The hydrophobic part is a transmembrane domain residing within the lipid bilayer. An integral membrane protein plays a critical role in the movement of molecules across the membrane and signal transduction. Insulin receptors, aquaporins, cell adhesion molecules such as integrin, cadherin, selectins, rhodopsin, and G-protein coupled receptors are typical examples of integral membrane proteins....

Mechanical waves are produced when particles vibrate in a medium through which the waves propagate. A longitudinal wave is a mechanical wave where the particles of the medium move parallel to the direction of wave propagation . Imagine a slinky stretched out on a flat surface. When you push one end of the slinky forward and backward, some coils compress while others spread apart. These regions of compression (where particles are squeezed together) and expansion or rarefaction (where particles are spread apart) create a longitudinal wave that travels along the slinky....

The mesophyll is ground tissue found between the leaf’s two epidermal layers. They consist of mesophyll cells and the bulk of the internal tissues of a leaf. These cells making up the mesophyll layer contain chloroplasts, thus making it the primary site of photosynthesis in green plants. The word ‘mesophyll’ is derived from two Greek words, ’ mesos’, meaning middle, and ‘phyllo,’ meaning leaf. Types of Mesophyll Cells with Functions The structure of mesophyll is best viewed with the help of a leaf cross-section under a light microscope....

What is Photosynthesis It is the process by which green plants, algae, and certain bacteria convert light energy from the sun into chemical energy that is used to make glucose. The word ‘photosynthesis’ is derived from the Greek word phōs, meaning ‘light’ and synthesis meaning ‘combining together.’ Jan Ingenhousz, the Dutch-born British physician and scientist, discovered the process of photosynthesis. Photosynthesis Diagram Where does Photosynthesis Occur Photosynthesis takes place mainly in the leaves of green plants and also in the stems of herbaceous plants as they also contain chlorophyll....

The first diagram is just incorrect. Plants absorb CO2 and release oxygen not the way it is in the picture.

Saprophytes, or saprotrophs, are heterotrophic organisms that obtain their nutrients by breaking down dead or decaying organic matter. They play a crucial role in breaking complex organic compounds into simpler forms, a process known as decomposition, and thus are also called decomposers. Examples of Saprophytes Saprophytes can be found in various kingdoms of life. They include: Fungi , such as mushrooms, molds like Penicillium , and yeast Some plants , like orchids and Indian pipe ( Monotropa uniflora ) Certain bacteria , like those belonging to the genus Bacillus and Clostridium Characteristics of Saprophytes Saprophytes possess a range of adaptations that enable them to thrive in their specialized ecological niche....

What is Stokes’ Law Stokes’ law is a mathematical equation for the drag force experienced by small spherical particles passing through a viscous fluid medium. It deals with the resistive (friction) force applied to a body under the action of gravity as it is dropped into a fluid – liquid or air. Historically, Stokes’ law has been named after Anglo-Irish physicist and mathematician George Gabriel Stokes after he derived the expression for drag force in 1851....
