There are many fuels that produce energy. Some are:
- Coal
- Nuclear Energy
- BioFuel
- Oil / Gas
Hope this helps!
It is b because many species live in an ecosystem
A competitive inhibitor will stop the reaction from happening because it blocks out the hydrolase from the enzyme, and a noncompetitive will try to block it but in a different way. The noncompetitives change the shape of the enzyme active site so that the hydrolase cant bond with it.
1. The study of cosmos is known as cosmology. It is a branch of physics and astrophysics, which deals with the study of origin and evolution of the universe. The cosmology includes the study of nature of the universe. The study of cosmos which is now known as cosmology was earlier known as the celestial mechanics.
2. Most of the astronomers gave different theories regarding the formation of the universe. The most accepted theory is the Big Bang theory. This theory was given by Dr. Stephen Hawkins. According to the Big Bang theory, the universe was formed during a giant explosion occured around 10 to 20 billion years ago. The explosion is known as the Big Bang explosion. Big bang is simply the expansion of the universe during which the energy, time and matter was created. During the expansion of the universe all the matter spread in the space in all the directions and also causes the expansion of space also. After the expansion of the space the universe started cooling due to which the matter, starts combining which are expected to form all the galaxies, stars and planets.
3. The two evidences that supports the Big bang theory are the Red shift and the Cosmic microwave background (CMB) radiation. Due to doppler effect the change in the frequency of the position of lines which represents the spectrum of helium moved towards the red spectum. Hence it is known as the red shift.
The CMB radiation is reffered to the microwaves which are coming from all the directions on the space. These microwaves are the energy waves which are created after the big bang and formation of the universe. All these energy or microwaves are continuously travelling in the space.
4. During the expansion of the universe all the matter spread in the space in all the directions and also causes the expansion of space also. The galaxies are formed and assembled in clusters due to the gravity.
5. The galaxies are the clusters of stars, it also consists of dust, gas concentrated in the galaxies due to the gravity. The study of galaxies helps to learn about the formation of the universe. These galaxies are visible so that the study of stars, planets become convenient for the astronomers.
