Take a nichrome wire of about 50 cm length and apply a potential difference of 1.5 V from a battery. Measure the current flowing through the wire using an ammeter connected to it in series, and note the potential difference across the resistance using a voltmeter connected acros..

This is the simplest type of modem to install because you don't have to open the computer. External modems have their own power supply and connect with a cable to a computer's serial port. The telephone line plugs into a socket on the rear panel of the modem. Because external modems have..

The iron object is connected to a more active metal either directly or through a wire. Fe acts as the cathode. The more reactive metal is the anode. It loses electrons and gradually disappears. Example: Fe can be connected to Mg, Zn or Al which are called the sacrific..

Water Pollution - Pollution of water is a broad subject dealing with different types of pollutants entering the hydrological cycle. Surface flowing river water, underground water and vast sea water are included in a broad subject of water pollution. Out of them, drinking water pollution is most imp..

Hypothalamus - The hypothalamus is a part of the brain, situated at the base of the fore brain. It consists of several masses of the grey matter called hypothalamic nuclei, scattered in the white matter. It is connected to the anterior lobe of the pituitary gland by hypophysal portal bloo..

P.R. Stout and Dr. Hoagland have proved that mineral nutrients absorbed by the roots are translocated through the xylem vessel. Mineral salts dissolved in water moves up along the xylem vessel to be transported to all the parts of the plant body. Translocation is aided, by transpiration. As water i..

The impulse is received by the dendrites and passed through the cell body to the axon. An impulse is an electrical disturbance. All along the nerve fibre, the cytoplasm is more electronegative than the outside and is thus having a potential. This is due to the differential distribution of sodium a..

>As copper is lower in the metal activity series, it does not undergo a similar reaction and hence remains a region of deficiency of electrons. So, when the zinc plate and the copper plate are connected by means of a metal wire, free electrons from the zinc plate flow to the cop..

Nucleus - Nucleus is the most conspicuous and the largest organelle in the cell. Most cells have a single nucleus and hence they are described as uninucleate. Some cells have two nuclei (binucleate) while a few may be even multinucleate. A nucleus generally occurs in all eukaryotic cells. However, ..

>The myosin molecule is shaped like a rod with a round head. Myosin rods form the long axis of the thick myofilaments and the heads form projections called cross-bridges, which connect to the active site present on the acti..
