... times more than the hydrogen atom. Atoms that make up one
alement are not like atoms that make up another element.
These (atoms) are not simple particles, their structure is very complexe.
They are, in fact, made up of smaller bits of matter called subatomic particles.
An atom has two parts. Those two parts are; 1)at the center is a nucleus, a
densely packed core composed of two kinds of paticles: protons and neutrons and
2)electrons. The charge in a nucleus of an atom is carried by a particle called
a proton, the number of protons in an atom's nucleus is calle the atomic number
of the atom. Ato ...

Mass And Science

... of matter.
Since we all live at the surface of the earth where the acceleration of gravity is relatively constant, it has been natural for us to confuse the concepts of mass and weight. To study the difference, we need to separate these two "parameters." We could either leave the earth's gravitational field so that we would have no weight, or create an experimental situation where weight is not a factor. An easy way to do this is to use floating objects. Floating objects still have all their mass, and move almost friction-free in still water, but we don't notice their weight since the water supports (o ...

... tissue. The body is enveloped in a thick layer of blubber that aids in bouyancy, helps to preserve body heat, and is a source of stored energy. A cetacean’s skin is free of sweat glands, oil glands, or hair, and feels much like smooth, wet rubber to the touch.
Cetaceans, like other mammals, have lungs. They breathe air through a single nostril, or pair of nostrils, located on the top of the head; but contrary to a popular image, they do not “spout” water when they exhale. The visible spout, the size and shape of which is unique to many species, is simply water vapor in the lungs and a small amou ...

... death situation. If the baby will not be able to live without the procedure being done, then it is acceptable. But nowadays, doctors are performing genetic engineering to pre-determine the baby’s sex. If parents are now allowed to choose the sex of their child, who can say where to stop? Every parent would want their child to be the "perfect" child. How the child looks, how it thinks, and anything else would be the parents choice and that is not their decision. It is God’s. This is not how God made the world to be. Sooner or later, every person will look and act the same. God made people to be ...

... plants and cars, the cumulative effect of air pollution poses a grave threat to humans and the environment.

multitude of worlds in a rather short period of time then deigns to lower
itself into becoming a puppet-master and "pulling the strings" of the Earth
and all of the people therein.
Since this paper touches upon many scientific terms, I feel that in

greater understanding of this essay and give us an even ground upon which
to begin.
