The 5 Largest Animals to Have Ever Lived on Earth

Image
Well, this list doesn't contain Godzilla or King Kong. So, you can have a glance of five humongous beasts that animals that once roamed on Earth: 1. Blue Whale (Balaenoptera musculus):    - Size: The blue whale is the largest animal to have ever lived on Earth. Adult blue whales can reach lengths of up to 100 feet (30 meters) or more.    - Weight: They can weigh as much as 200 tons (approximately 400,000 pounds).    - Amazing Facts: The tongue of a blue whale alone can weigh as much as an elephant, and its heart can be as large as a small car. Despite their immense size, blue whales feed primarily on tiny shrimp-like animals called krill. They are known for their deep, haunting songs that can be heard over great distances. 2. Argentinosaurus (Argentinosaurus huinculensis): - Size: Argentinosaurus is one of the largest known dinosaurs. It was a long-necked sauropod dinosaur that could reach lengths of around 100 to 130 feet (30 to 40 meters).    - ...

Acids and Bases

Image
Acids and bases are fundamental concepts in chemistry that describe two distinct types of chemical substances based on their properties. Let's explore each of these concepts in more detail. What are Acids? Acids are substances that can donate protons (H⁺ ions) in a chemical reaction. They typically have a sour taste, can turn blue litmus paper red, and have a pH value less than 7. Acids can be categorized into two main types: - Strong acids: Completely dissociate in water, releasing all their protons. Examples include hydrochloric acid (HCl), sulfuric acid (H₂SO₄), and nitric acid (HNO₃). - Weak acids: Partially dissociate in water, releasing only some of their protons. Examples include acetic acid (CH₃COOH) found in vinegar and citric acid (C₆H₈O₇) found in citrus fruits. And What are Bases? Bases are substances that can accept protons (H⁺ ions) in a chemical reaction or donate hydroxide ions (OH⁻). They typically have a bitter taste, feel slippery, and turn red litmus paper blue....

The Human Digestive System

Image
The human digestive system is the system of organs that take part in breaking down of food to release energy and absorb nutrients. It consists of two parts: alimentary canal and digestive glands. Alimentary canal(or gut) is the path which food takes from the mouth to the anus. Digestive glands are associated with it and secrete digestive juices and enzymes to help in digestion. ‌ Journey of Food Mouth When we take in food, it enters our mouth. Our mouth is the anterior opening of the digestive system. Digestion of food begins here. The space in the mouth is known as buccal cavity. The Teeth, tongue and salivary glands are present here. Teeth An adult person has 32 permanent teeth and 16 in each jaw. There are four types of teeth in humans: incisors, canines, premolars and molars. We have 8 incisors, 4 canines, 8 premolars and 12 molars in our mouth. Incisors are used for cutting food, canines for tearing food whereas premolars and molars are used for grinding and crushing food...

Males are generally larger than females, with an average length of around 9 to 12 feet (2.7 to 3.7 meters), ...

Photosynthesis

Image
Photosynthesis is a vital biological process in which plants make their own food. They combine Water and Carbon dioxide to make Glucose and Oxygen in the presence of chlorophyll and sunlight.  How does it happen?  First of all, plants need water. They have roots that suck in water and nutrients from the soil. Plants have two distinct type of vessels that run through the stem - xylem and phloem. The roots end their collected water to the xylem which transports it to the leaves.  After this plant need Carbon dioxide. They have tiny microscopic pores on their leaves called stomata. These are surrounded by guard cells that open and close to take in air.  Is that enough? Well, No. Plants need sunlight to process their food. To absorb it they have special pigments called chlorophyll. During photosynthesis, chlorophyll absorbs energy from blue- and red-light waves, and reflects green-light waves, making the plant appear green. Then an endothermic reaction takes place w...
