activity connection

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..

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..

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..

Impulse transmission through the conduction system generates electrical currents that may be detected on the body's surface. A recording of the electrical changes that accompany the cardiac cycle is called an Electrocardiogram (ECG). The instrument used to record the changes is an Electrocardiograp..

>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..

>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..

. Transition State explains the rate of reaction in term of formation of a transition state of reacting molecules. The formation of transition state requires energy of activation. Transition state theory connects kinetic rates with thermodynamic properties of reactants and the t..

Earthworms possess a similar simple tubular excretory system called the metanephridia. A metanephridium has internal openings or nephrostomes that collect coelomic fluid when the cilia present on the funnel shaped opening beat. Metanephridia have both excretory and osmoregulatory functions. Cru..
