The genes we inherit from our mother & father determine our blood group.
Blood is explained by the type A, B, AB or O & the Rhesus (Rh) factor. The Rhesus factor is a protein which is either present or absent on the surface of our red blood cells. In medical this is indicated by a plus sign (+) or a minus sign (-). Best example, the blood type O+ means which the blood is type O & each blood cell has the Rhesus factor.
A blood group is recognized by a collection of inherited chemical substances (antigens) located on the surface of each red blood cell. The antigens, with the Rhesus factor, help the body to distinguish its own blood from the blood of another person.

Boron family exists in the earth's crust to the extent of only about ten ppm. The pure & original element is shiny & black. Boron is very hard & in extremely pure form is nearly as hard as diamond, but much too brittle for practical use. At high temperatures boron is a good conductor but at room temperature & below is an insulator. This behavior & many of its other properties earns it the classification of a metalloid. In order to the crystalline form of boron there is also an amorphous dark brown powder
Boron exhibit -3 oxidation state in borides example Mg3B2
No regular trend is noticed in the melting points of these elements in order to the structural changes in the elements. The M.P is high because it exists as large covalent polymer in solid & liquid states. The low melting point of gallium is because to its simple molecular structure.
Boiling point decrease frequently in boron family

Weight of human heart is 10-12 ounces for a male & 8-10 ounces for a female. The weight increases with age & is especially noticeable in males.
Man heart weight is 300g
Female heart weight is 200g
The Weight of human heart is between 200 g - 450 g, however, this number can be extremely varied when the heart is diseased. A heart which is deceased can sometimes weigh as much as 1000 g; more than 2 pounds! The human heart is located between the lungs & in approximately the middle of the chest, slightly left of the breast bone. Approximately 2 thirds of its mass lies to the left of the body's midlines. In an average adult weighing approximately 80 kg, the human heart is approximately 0.3% of the total mass.

Mechanical waves are referred as a local oscillation of material. Only the energy propagates; the oscillating material does not travel far from its initial equilibrium position; the wave travels by jumping from 1 particle of the medium to another. Hence, mechanical waves transport energy & not material
Water waves, Sound waves, & waves in solid objects are all best example of mechanical waves
A mechanical wave is the transport of energy through a medium
Make a note that it is energy which is moving and not the material through which the energy travels.

The nucleus of the cell includes much of the DNA of the cell, & it regulates the activities of that cell, whatever those activities are. The nucleus is compiled of chemical structures that orchestrate chemical reactions that make the cell function. It is the nucleus, or, rather, those things in it, which control what the cell does, including those activities that keep the cell alive, as well as the things it does to contribute to the functioning of the organism whose structure it is a part of.
The nucleus controls & manages all cell activity. The nucleus has the capacity to copy exactly, its own DNA. The nucleus is a circular central form.

Graham's law is also called as Graham's law of effusion, was formulated by Scottish physical chemist Thomas Graham. Graham invented experimentally that the rate of effusion of a gas is inversely proportional to the square root of the mass of its particles.
Graham's law affirms that the rate of effusion of a gas is inversely proportional to the square root of its molecular weight. Thus, if the molecular weight of 1 gas is 4 times that of another, it would diffuse through a porous plug or escape through a small pinhole in a vessel at half the rate of the other. A complete theoretical description of Graham's law was provided years later by the kinetic theory of gases. Graham's law impart a basis for separating isotopes by diffusion — a method that came to play a crucial role in the development of the atomic bomb.

Solubility formula of a substance is its highest amounts which can be dissolved in a specified amount of solvents at a specified temperature. Solubility formula depends leading the environment of solute & solvent as well as temperature & pressure.
Let us learn about metallurgical process The method of extracting a metal from its ore & refining it, is said to be as metallurgical process or simply as metallurgy.
There are a variety of metallurgical process generating off-gases including a variety of SO2 concentrations & impurities. Each process is special & unique that dictates the gas be treated in different ways in order to remove impurities & treat the SO2 in the gas
A metallurgical process for bending steel bars & rods to the desired finished curvature or straightness without the normally expected losses in strength properties by bending the steel to straighten, etc., while at a temperature within the range of 300°-900° F. & preferably 400°-700° F. Steels that respond to such treatment are of the type that precipitation harden in response to such bending.

The frog is covered by thin, a soft, moist skin composed of 2 layers, an inner dermis & an outer epidermis. The skin does not only protect the frog but also helps in respiration
A broad network of blood vessels runs throughout the frog's skin. Oxygen pass through the membranous skin, thereby enters directly into the blood. When a frog immerse beneath the water, all frog’s respiration takes place through the skin. Oxygen can be obtained directly from the water.
The frog does not breathe through its skin alone. Adult frogs have saclike lungs, paired simple, as in man, air enters the body through 2 nostrils, passes through the windpipe, & is received by the lungs. The mechanism of breathing is different in the frog from that in man. In human beings breathing is aided by the ribs, the diaphragm, & the chest muscles. The frog has no ribs or diaphragm, & its chest muscles are not involved in breathing.
A frog may breathe by simply opening its mouth & letting air flow into the windpipe. However, it may also breathe with its mouth closed. The floor of the mouth is lowered, causing the frog's throat to "puff out." When the nostrils open, air enters the enlarged mouth. Then, with nostrils closed, the air in the mouth is forced into the lungs by contraction of the floor of the mouth.

Bacteria are one of the germs which cause infection. Bacteria are prokaryotic organisms which reproduce asexually. Bacterial reproduction most commonly takes place by a kind of cell division said to be as binary fission. Binary fission results in the formation of 2 bacterial cells which are genetically identical.
Bacterial reproduction most commonly takes places by a kind of cell division is said to be as binary fission. Binary fission results in the formation of 2 bacterial cells that are genetically identical. During binary fission the single DNA molecule replicates & both copies attach to the cell membrane. The cell membrane begins to grow between the 2 DNA molecules. Once the bacterium just about doubles its unique size the cell membrane begins to pinch inward. A cell wall then forms between the 2 DNA molecules dividing the original cell into two identical daughter cells.

plot line graph is called as a Cartesian co ordinate’s plane. Plot line graph contains a couple of vertical lines is said to be as coordinate axes. The horizontal axis value is the x axis value & the vertical axis y axis value. The points of intersection of those 2 axes values are said to be the origin of coordinate graphing pictures. Moreover, point to a right of the origin on the x axis value & above the origin on the y axis represents positive real numbers. The points to the left of the origin value on the x axis or below the origin on the y axis represent negative real numbers. In this blog we shall discuss about plot a line graph.
Plot line graph are more popular than all other graphs combined because their visual features reveal data trends clearly and they are easy to create. Particularly, a line graph is a set of quantitative data, plotted in an x-y coordinate system, that are connected together by lines. The data used to create a line graph must be composed of pairs of observations. The best example, a time series is composed of pairs of values: measurements or statistics of some type, & the time periods during which those measurements were taken or for which those statistics were estimated.
Merits of using line graphs include:
Plot line graph are good at showing specific values of data, meaning that given one variable the other can easily be determined.
Plot line graph show trends in data clearly, meaning that they visibly show how one variable is affected by the other as it decreases or increases
Plot line graph enable the viewer to make predictions about the results of data not yet recorded.

Nitrogen has several uses. 1 of these uses is preparing light bulbs. Light bulbs are almost always filled with Nitrogen. Another use is explosives. Nitrogen can be used to make 4 different explosives. 1 of these is Ammonium Nitrate (N2 H4 O3). During1947, a shipload of Ammonium Nitrate went off in the harbor of Texas City, TX. The explosion wrecked the city therefore thoroughly; it seemed that airplanes had bombed the city. The other 3 explosives made from Nitrogen are Nitrocellulose, Nitroglycerin, and Trinitrotoluene. You may know Trinitrotoluene better by the initials TNT. Hence another use for Nitrogen is that it is used to make Laughing Gas.
One field for use is to save the freshness of foods by packaging them in nitrogen. This greatly helps us to reduce the spoilage of the food, due to it getting rancid or suffering other forms of oxidative damage.
Argon gas has been used in incandescent light bulbs to preserve the tungsten filament from burning up, since argon is an inert material. At present Nitrogen is being used as an inexpensive alternative to argon.
Other fields where nitrogen is used is in dealing with liquid explosives as a safe measure, in military aircraft fuel systems to reduce the fire hazard, & in the production of electronic parts such as diodes, transistors & integrated circuits.

An ionic compound is a chemical compound in that ions are held together in a lattice structure by ionic bonds. Generally, the positively charged portion consists of metal cations & the negatively charged portion is an anion or polyatomic ion. Ions in ionic compounds are apprehended together by the electrostatic force between oppositely charged bodies. Ionic compounds have boiling point & a high melting & they are very brittle & hard
Ionic compounds are basically defined as being compounds where 2 or more ions are held next to each other by electrical attraction. One of the ions has a positive charge (called a "cation") and the other has a negative charge ("anion"). Cations are generally metal atoms & anions are either nonmetals or polyatomic ions
Those molecules that made up of charged ions with opposite charges are called IONIC. These ionic compounds are usually solids with high melting points & conduct electrical current. Ionic compounds are generally formed from metal & non-metal elements.

Muriatic acid is nothing but Hydrochloric acid. Anciently Muriatic acid was also known as spirits of salt & was prepared from the reaction between vitriol &common salt.
Muriatic acid comes in the category of monoprotic acid, hence Muriatic acid dissociate only once to give H+ ion.
Hydrochloric acid is an aqueous solution of (HCI) gas. Muriatic acid is a highly corrosive acid. Muriatic acid is used commonly as a reactive chemical solution
A wide range of Hydrochloric Acid (HCl) is manufactured, which has been appreciated by many clients for its quality and performance. Muriatic acid is known as a strong acid & it is a foremost component of gastric acid.
The octet rule indicates that atoms tend to gain, lose or share electrons so as to have eight electrons in their outer electron shell. It is useful rule but we should also know that there are many bonding situations where it does not apply.
The octet rule turns out to be violated almost as much as it is followed. The octet rule comes from the realization that since atoms wants to have noble gas structure and some noble gases have eight electrons in their valence shell, atoms should have eight electrons around them.
The atoms that commonly follow the octet rule are
Carbon: C
Nitrogen: N
Oxygen: O
The halogens, F, Cl, Br, I
Each of these above atoms will probably have 8 electrons around it.
