Glycogen is the principal storage form of carbohydrates in animals, similar to starch in plants. It is a highly branched polymeric structure of α-D glucose linked to each other by a 1→4 glycosidic bond and a branching after 7-8 glycosidic residues by a 1→6 glycosidic bond. Glycogenesis is the biosynthesis of glycogen, the carbohydrate stored in the liver and muscle cells, by adding glucose molecules chain-wise. It is an anabolic process that requires one ATP molecule per glucose incorporated into the glycogen....

Grasslands are characterized by open spaces dominated by grasses and a variety of other plants. These ecosystems receive low to moderate rainfall, which is insufficient to support the growth of large plants. The Grassland biome is present on every continent except Antarctica. Plants in the grassland, like savanna and prairie, have developed several adaptations to endure the challenges of their environment. The three main types of adaptations are described below:...

What is Passive Transport Passive transport is defined as the movement of ions and other atomic or molecular substances from an area of high concentration to an area of low concentration without any energy input. Why is Passive Transport Important to Cells The main function of passive transport is to control the entry and exit of substances to and from the cell by means of a selectively permeable membrane. Also, it helps the system to attain a state of equilibrium by equalizing the concentration of substances in both regions....

What is Pinocytosis Pinocytosis, also known as fluid endocytosis, fluid-phase endocytosis, and bulk-phase pinocytosis, is defined as the process where a cell ingests tiny particles suspended in the extracellular fluid by forming an endocytic vesicle called a pinosome. The term pinocytosis combines two Greek words, where ‘pino’ means ‘to drink’, and ‘kytos’ denotes ‘cell’. So, the word stands for ‘cell drinking’. It involves the transport of extracellular fluids along with its contents of small dissolved molecules (solutes)....

Absolutely simplified, but extremely helpful. Thank you very much.

I LIKE YOUR NOTE THANKS!!!

What is Anaerobic Respiration and Where Does it Occur The term ‘anaerobic’ stands for ‘absence of air or free oxygen.’ Accordingly, anaerobic respiration is a type of cellular respiration, in which stored energy of glucose gets converted into biochemical energy coins, ATP without free oxygen. Many microorganisms rely on this process to produce energy when there is a lack of oxygen. These include prokaryotes, like bacteria and Archaea, and eukaryotes, such as plants and animals....

What is a Nucleus The nucleus is a double membrane-bound organelle located centrally only in a eukaryotic cell, enclosing the DNA, the genetic material. It is the most important and defining feature of all higher organisms, including plant and animal cells, whose main function is to control and coordinate the functioning of the entire cell. The word ‘nucleus’ (plural: nuclei) is derived from the Latin word ‘ nucleus ‘, meaning ‘kernel’ or ‘seed’....

Wonderful teaching and if possible send for me some sample question and their answers.thank

Radioactive decay, also known as nuclear decay, radioactivity, or radioactive disintegration, is a fundamental process in nuclear physics. It is a process in which an unstable atomic nucleus loses energy to become stable. It is a natural process and is important for medical imaging and determining the age of rocks and fossils. What Happens During Radioactive Decay Radioactivity occurs when an atom has an excess of energy, mass, or both, making its nucleus unstable....

Speciation is an evolutionary event through which new species arise from preexisting ones. It occurs when a group of members within a species becomes isolated, develops unique characteristics, can no longer interbreed with other members of the population, and evolves independently over time. An example of speciation is Darwin’s finches on the Galápagos Islands. Finches on islands with hard seeds evolved stronger, larger beaks to crack them, while those on islands with insects or soft fruits developed smaller, pointed beaks....

The Stefan-Boltzmann law states that “the total radiant power emitted by a surface across all wavelengths is proportional to the fourth power of its absolute temperature”. The law generally applies to black bodies that absorb all radiation falling on them. Stefan-Boltzman law is named after Austrian physicists Josef Stefan and Ludwig Boltzmann. Stefan formulated the law in 1877, and Boltzmann derived it in 1884. Formula Suppose P is the radiant heat energy emitted per second, A is the surface area of the emitter, and T is the temperature of the surface in absolute scale....

A transposon, also called a transposable element (TE) or jumping gene, is a segment of DNA (500–1500 bp long) that can move throughout the genome. Eukaryotic cells, including humans, typically contain them in large numbers. Almost 45% of the human genome, 90% of the maize genome, 12% of the C. elegans genome, and 37% of the mouse genome contain transposons. Prokaryotic cells also have them. They were discovered in the 1940s by geneticist Barbara McClintock in maize ( Zea mays )....

The tundra is a very cold, dry, and tough environment found in the Arctic ( Arctic tundra ) or on mountain tops ( Alpine tundra ). Temperatures usually range from 3°C to 12°C (37°F–54°F) but can drop below -30°C (-22°F). The tundra has poor soil, strong winds, little sunlight, and soil that is often frozen, making it hard for plants to grow roots. Examples of plants that live in the tundra include Arctic moss, lichen, Arctic willow, Bearberry, and blueberry bushes....

A liquid is a substance that takes the shape of a container to which it is confined. It is made up of molecules, which are separated by empty spaces called voids. The molecules are bonded by weak intermolecular forces, often by van der Waals forces. The compressibility of a substance is its ability to deform upon the application of force. Liquids are not compressible under normal circumstances. Why do Liquids Not Compress Easily Under Normal Circumstances The compressibility of a liquid depends upon its intermolecular bond and the spacing between the molecules....

What is a Cell Wall The cell wall is a rigid and protective outer covering commonly found in both prokaryotic and eukaryotic organisms such as plants, fungi, algae, bacteria, and archaea, but is absent in all animal cells. It is a non-living structure that varies in color and composition depending on the type of organism, and is freely permeable to natural substances. The cell wall performs many important purposes in a cell, including protection, structure, and support....

Electron capture is a type of radioactive decay that happens inside an atom’s nucleus when one of its inner (K or L shell) electrons is pulled in and combined with a proton. When this happens, the proton turns into a neutron. A new atom is formed, and a tiny particle called a neutrino is released. Electron capture usually happens in atoms that have too many protons and cannot release energy by other means....

It’s very good. My name is Anantika Samal. I am studying in class 6. I am 12 years old.
