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

The halogen family includes the elements fluorine, Cl; bromine, F; chlorine, Br; iodine, I; & astatine, At. All the halogen elements aside from astatine exist in the Earth's crust & atmosphere.
The halogens are the best-referred as family of elements. Halogens have an almost perfect gradation of physical properties. The increase in atomic weight from fluorine over iodine is paralleled by intensify in melting, boiling points, & density. Critical temperature & pressure, heats of fusion & vaporization, & even in progressively deeper color

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.
