Sugar(glucose) and oxygen.
This is the Prophase.
<span>1) The chromosomes coil up and become visible while the nuclear envelope disappears.
2) Sister chromatids are appears.
3) A centriole forms at each pole and spindle fibers made of microtubules grow out of it.
4) Short microtubules stick out from the centriole in a star shape known as an aster.
I don't remember liking biology but I do remember some things from it.</span>
The protein structures can be classified into four levels, namely the primary structure, secondary structure, tertiary structure, and quaternary structure. The primary structure is the simplest of all the structures. When all the hydrogen bonds are disrupted, the secondary, tertiary and the quaternary structures gets disrupted, which leads the protein to the most simplest structural form, that is the primary structure. In this structure, the a carbon atom is bonded to hydrogen atom, carboxyl group, amino group, and an 'R' group.
1. Radiation - energy transmits through particles that ionize. Conduction - heat is transferred through a substance without moving the material. Convection - transfer of heat through movement.
2. Earth receives energy from the sun, which is transferred between Earth and its atmosphere.
3.<span>Wildland fires, dust storms, and volcanic activity. They release CO2, CH4, N20, and sulfur dioxide.</span>
4. Burning coal, releases carbon dioxide and other pollutants. Gasoline, releases air pollution. Factories, releases carbon dioxide, methane, and nitrous oxide.
