Indeed the Mysterious Universe

Dark Matter and Dark Energy

95% is the percentage of matter and energy in the Universe that is currently unobservable.

Matter and energy are the two basic components of the entire Universe. An enormous challenge for scientists is that most of the matter in the Universe is invisible and the source of most of the energy is not understood.

Modern calculations say dark matter comprises about 26% of the Universe. We don’t yet know what it is, but we are searching for answers.

We have known that the Universe is expanding since the early 20th century. But recent observations of distant supernovae and other observations show that the Universe is not only expanding, but the expansion is accelerating. This astonishing discovery came as a complete surprise because the expansion of the Universe should slow down with time because of the gravitational attraction between galaxies and clusters of galaxies. The unseen repellant force required to explain this observation has been labelled “dark energy,” and current models say it makes up about 69% of the Universe. That leaves only 5% of the Universe that is visible to us.

What are characteristics shared by all living organisms?

LIVING THINGS. - ppt video online download

The things that live here on Earth all have a lot in common. The tiny parts inside you that are responsible for helping you do everything you do, like walking, breathing, and digesting your food – those tiny parts are almost exactly the same in all types of life, from flies and fish to trees and cows.

All types of life have other things in common, too. All living things have a body of some kind. Some things have body parts that allow them to walk or fly or swim. These are things like legs and wings and fins. All of the living creatures we know have to eat food in order to have the energy to move and grow. All living things can respond to their surroundings, just like you can taste something awful then spit it out and shout “YUCK!” And all life comes from other life – just like how you came from your mother and father. So even though we look so different from other living things, we are much more the same than different. There are many characteristics shared by all living organisms on Earth.

For example, all known organisms are highly complex chemical systems. They have thousands of interdependent molecular components. Even the simplest life forms are capable of hundreds of different chemical reactions, and these reactions wouldn’t occur otherwise in nature. They don’t occur spontaneously; they only occur in living things. Most of life’s chemical reactions require enzymes: these are molecular catalysts. They greatly increase the efficiency of reactions, and the catalyst or the enzyme itself is a molecule that doesn’t change in the process of facilitating that chemical reaction.

These are traits that human beings share with other living things.
