Mitosis is the process of cell division that creates a new cell identical to the original. Somatic cells, such as muscles, hair and skin, undergo mitosis regularly in humans and other organisms. This is an important type of cell division needed to facilitate the repair of damaged cells, growth and replacement of old cells with new ones.
When a new cell is created, it must have the same library of genetic information all other cells in the body have access to. Because all the material in the new cell must come from the first cell, the original cell must make a copy of its DNA before completing the process of mitosis. These two sets of DNA only exist for as long as it takes the cell to undergo mitosis, which can be anywhere from 30 to 90 minutes in certain human cells. When the cell division is complete, both of the cells have a single identical copy of DNA.
Competitive inhibition can be overcome by increasing the concentration of substrate while uncompetitive and noncompetitive inhibition cannot. Enzyme inhibitors are molecules or compounds that bind to enzymes and result in a decrease in their activity.
Answer AND Explanation:
When sodium atoms bond with one oxygen atom they form a covalent bond. However, there has to be two sodium atoms each with an extra electron that are donated to oxygen. Each of these sodium atoms gives oxygen one electron, allowing the oxygen atom to have a full shell with eight electrons. The sodium atom loses one orbital level since the electrons are donated.
4Na + O2 → 2Na2O

Explanation:
What is a divergent boundary:
In plate tectonics, a divergent boundary is a linear feature that exists between 2 tectonic plates <u>moving away</u> from each other.
They can produce rifts, which become rift valleys.
Divergent boundaries also form <u>volcanic islands</u>, which occur when the plates move apart to produce gaps that magma rises to fill.
<u>Sedimentary rocks</u> form due to <u>deposition, and accumulation</u>
<u>Metamorphic rocks</u> form in a <u>transformation</u> of existing rock to new rock in a process called <u>metamorphism</u>.
<u>Igneous rocks</u> form through the <u>cooling and solidification of magma or lava</u>.
When the filled gaps of magma cool off, it will produce <u>igneous rocks</u>.
