The property of a body by which it resists any change in the state of rest or uniform motion in a straight line is called inertia. It is described by Newton’s first law of motion, often summarized as “an object ...
Swimming in water is possible due to Newton’s third law of motion. This law states that for every action, there is an equal and opposite reaction. The action of pushing against the water with hands and feet results in a ...
For every action, there is a reaction in equal and opposite direction. This is called Newton’s third law of motion. It states that when one object exerts a force on another object, the second object exerts an equal and opposite ...
Fungi store reserved or accumulated food substances in the form of glycogen. Glycogen serves as their primary energy reserve, akin to how animals store energy in the form of glycogen. It acts as a readily accessible energy source when needed ...
The cell wall of fungi is made of chitin and hemicellulose. Chitin, a polysaccharide, provides structural support and rigidity to the cell wall, while hemicellulose contributes to its strength and flexibility. This composition distinguishes fungal cell walls from those of ...
Agar-agar is obtained from algae. Specifically, it is extracted from the cell walls of certain species of red algae, such as Gelidium, Gracilaria, and Pterocladia. This polysaccharide-rich substance is commonly used as a gelling agent in various food and microbiology ...
The red color of the Red Sea is due to the presence of algae. Specifically, it’s caused by a type of algae called Trichodesmium erythraeum, also known as “sea sawdust” or “red tide.” These algae contain pigments that give the ...
The unicellular algae used to control the supply of oxygen in space programs is Chlorella. Chlorella is known for its rapid growth rate and high oxygen production, making it an ideal candidate for maintaining oxygen levels in closed environments such ...
Blue green algae act as bio-fertilizer for rice crop. They form symbiotic relationships with rice plants, fixing atmospheric nitrogen into a form usable by the plants. This enhances soil fertility and promotes healthy growth, ultimately increasing rice yield and sustainability ...
