Rainforests are found near the equator. These regions are hot, humid, and wet, ideal for plants to grow and make food by photosynthesis. Among all biomes, tropical rainforests do not house a great variety of plants. They also provide food and shelter to various animals, including some rare species on Earth. How many Layers are there in a Tropical Rainforest A tropical rainforest is divided into four different layers. Each rainforest layer forms a habitat for a different group of plants and animals....

What are Ribosomes Ribosomes are cell structures present in large numbers in all living cells acting as the site of protein synthesis. In prokaryotes, they float freely in the cytoplasm, while in eukaryotes they are free or remain bound to the outer membrane of the endoplasmic reticulum. They are also found in the mitochondria and chloroplast of a eukaryotic cell. Ribosome Structure Diagram Location Their location in a cell determines what kind of proteins it makes up....

it is nice

I am studying about simple machines and their examples. This website is really helpful to me. It gives a lot of examples of simple machines. Thank you!

I’m very glad to find appropriate site to solve my doubts. Fantastic article! Thanks for sharing with us.

Ammensalism is a symbiotic interaction in which one organism is harmed or inhibited while the other is unaffected. Unlike mutualism, where both species benefit, or competition, where both species are negatively affected by their interaction, ammensalism is characterized by its lopsidedness. Also, ammensalism is not a type of predation or parasitism where one species actively benefits at the expense of another. Instead, ammensalism often arises as a side effect of an organism’s activities without any direct intention to harm or help another....

I love how your post simplifies the reverse osmosis process for non-science readers (like myself!). When a ro system boasts a water-to-waste ratio, is the wasted water due to the osmosis or the diffusion process?

Oxygen is essential to every living species for their survival. Lack of oxygen for an extended period can lead to the death of a living being. Human cells require oxygen in the final stage during aerobic cellular respiration, commonly known as oxidative phosphorylation. Two major components that form oxidative phosphorylation are electron transport chain and chemiosmosis. What is the Electron Transport Chain The electron transport chain (ETC) is a group of proteins and organic molecules found in the inner membrane of mitochondria....

The hydrosphere refers collectively to all forms of water on Earth. It includes surface water bodies like rivers, oceans, lakes, and ponds, groundwater, water vapor (clouds and fog) in the atmosphere, and ice. Hydrosphere clearly distinguishes our planet from others, as almost two-thirds of the Earth is covered with water. However, not all water is available to us. The water below the water table cannot be made available for human use....

What is Hydrotropism Hydrotropism is a type of tropic movement by which some plant parts, specifically root and stem, tend to move towards or away from water stimulus. The term ‘hydrotropism’ is a combination of two words, ‘hydro’ and ‘tropism’. Here, ‘hydro ‘means ‘water’, and ‘tropism’ stands for ‘tropic movement’. Tropic movement is a directional movement displayed by a plant in response to any external stimuli, such as light, gravity, chemical, touch, temperature, and water....

Lactic acid fermentation is anaerobic respiration occurring without oxygen that breaks down sugars, producing energy in the form of ATP. This process is so named because lactic acid is a byproduct of this reaction. A typical example of lactic acid fermentation is making yogurt by the bacteria Lactobacillus . History of Lactic Acid Fermentation It was first discovered in 1780 by a Swedish chemist, Carl Wilhelm Scheele, who isolated lactic acid from sour milk as impure brown syrup....

Otto cycle is a hypothetical thermodynamic cycle used mainly by spark ignition internal combustion engines. It describes what happens to a gas when it is subjected to a change in temperature, pressure, volume, and heat exchange. Therefore, the Otto cycle can explain how gasoline is converted into motion, specifically how chemical energy is converted into thermal and mechanical energy. Otto cycle is named after German engineer Nikolas Otto, the first to build a working four-stroke engine in 1876....

Meteorites are solid debris that originates in outer space and survives through the passage of the earth’s atmosphere to reach its surface. Due to high friction, pressure, and chemical reaction with atmospheric gases, they heat up and radiate energy, forming fireballs that are called ‘shooting stars’. This debris typically originates from comets, asteroids, or meteoroids. How many Types of Meteorites are There There are three different types of meteorites based on the proportions of rock-forming minerals and metallic materials (iron-nickel) in their composition....

What are Viruses Viruses are tiny, infectious agents that live and multiply only inside a living cell. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. A complete virus particle with all its parts that can infect a host organism is called a virion. Viruses were first discovered in 1898 by Dutch scientist Martinus Beijerinck. Virus Under Microscope Picture Basic Characteristics of Viruses Are They Alive Although Viruses display both living and non-living features, they are not considered alive because they lack most of the properties of a living organism....

What is Carbon Fixation Carbon fixation, or carbon assimilation, is how plants fix inorganic atmospheric carbon (mainly CO 2 ) into organic compounds. The compounds thus formed can be used as energy sources and for the synthesis of several biomolecules. It is a light-independent process, similar to photosynthesis taking place in the dark. All the autotrophs, algae, bacteria, and plants fix CO 2 primarily by photosynthesis. However, some organisms also use chemosynthesis in the absence of sunlight....
