Magnets

Science > Physics > Magnetism > Magnets About 600 to 800 BC the people living in Magnesia in Asia Minor found a stone (an ore of iron Magnetite Fe2O3) which was capable of attracting iron pieces towards it. They called this stone as magnetite. During the course of time, the name changed to a magnet. […]

Blood Plasma

Science > Biology > Human Anatomy and Physiology > Cardiovascular System > Composition of Blood: Blood Plasma When a human blood sample is prevented from clotting and spun in a test tube (centrifuged), in a machine called a centrifuge, the blood separates into a straw coloured liquid called plasma and a dark brown mass […]

The Blood

Science > Biology > Human Anatomy and Physiology > Cardiovascular System > The blood, an Overview In the Cardiovascular system, the ‘‘heart’’ (cardi) pumps the blood in a ‘‘little circle’’ (circul), which travels through ‘‘little vessels’’ (vascul). In human, the transportation is done through blood circulatory system and lymphatic system. Thus two fluids move through […]

No Comments on Circulatory System and its Functions

Science > Biology > Human Anatomy and Physiology > Cardiovascular System > Circulatory System and its Function In living things, many substances such as food, gases, minerals salts, hormones and waste products have to be transported from one part of the body to another. Plants and animals have a system of transporting substances throughout their body. […]

Nutrition

Science > Biology > Digestion and absorption in Human > Nutrition Energy is required by living beings for performing different activities. Energy is contained in the food. Food can be defined as a collection of chemicals taken by an organism for the purpose of the growth, repair, and replacement of body cells, energy releases, and […]

Types of Forces

Science > Physics > Force > Types of Forces Depending upon the interaction between the bodies and level of contact forces are classified a) Contact forces b) Non-contact forces. Muscular force is a contact force. Electrostatic force is non contact force. Contact Forces: A force which can be applied only when it is in contact […]

The Leaf

Science > Biology > Botany> Morphology of Plants > The Leaf The body of a typical flowering plant can be divided into the underground root system and aerial shoot system. The shoot system is heterogeneous. The shoot system (stem) is an aerial and erect part of the plant body that grows upwards. It is usually above […]

Modification of Stem

Science > Biology > Botany> Morphology of Plants > Modification of Stem In this article, we shall study the modification in stem in some plants for performing the functions other than its primary function. Primary functions of the stem are To support and orient the leaves in a manner that they are exposed to maximum sunlight […]

Modification of Roots

Science > Biology > Botany> Morphology of Plants > Modification of Roots In this article, we shall study the modification of roots for the purpose of food storage, respiration, support, etc. Roots in some plants change their shape and structure and become modified to perform functions other than absorption and conduction of water and minerals.
