. This difficulty is often overcome in high-fidelity systems by employing two speakers, a cone and baffle to provide the low frequencies up to possibly 1,000 cycle to 1,600 cycle, and a small high frequency horn to carry the frequencies above. The amplifier output is divided into two frequency rang..

The chromatin network condenses into chromosomes, which are long and slender threads. Each thread is a single chromatid, and not double as in Mitosis. Two homologous chromosomes come together and lie side by side. Pairing takes place along their entire length. The two homologous c..

The plasma membrane or cell membrane surrounds the cell contents in all types of cells. It is a multipurpose covering composed of phospholipids and proteins. fig. 16.4 - Cell Membrane Apart from the plasma membrane, an eukaryotic cell also shows intracellular and subcellular membranes around its or..

Inside the renal medulla, the efferent arteriole forms a capillary network around the tubules. Some of these blood capillaries are parallel, wide, thin walled, straight and loop like and are called vasa rectae. The blood flows in opposite directions in the 2 limbs of the vasa rectae. Blo..

In covalent crystals, the constituent particles are atoms of the same or different kind, which are bonded to one another by a network of covalent bonds. The important characteristics of covalent crystals are: The covalent crystals are incompressible and hard. They are extremely non-..

The simplest approach to the design of modems is to treat the entire PSTN as a linear analog network. [Note that PSTN is almost entirely due to the use of pulse-code modulation (PCM) for the transmission of voice signals.]..

In nature, the food and feeding relationships of plants and animals are rarely as simple as the examples of food chains described above, because many animals eat more than one kind of food. On this account, different kinds of food chains overlap each other or intercross each other. The food chains..

Chromosomes - Chromosomes (chroma = colour, soma = body) are tiny thread-like structures found in the nucleus of a cell. In a non-dividing cell they appear as a chromatin network while during cell division they become condensed to form short and thick chromosomes. Chromosomes are unique c..

Symmetric Modem Configuration - The simplest approach to the design of modems is to treat the entire PSTN as a linear analog network. [Note that PSTN is almost entirely due to the use of pulse-code modulation (PCM) for the transmission of voice signals..

A characteristic property of the elements of groups 14 is that these show allotropy. Allotropy is the existence of an element in two or more forms, which are significantly different in physical properties but have similar chemical properties. The difference may be due to difference in crystal stru..
