Answer:
A
Explanation:
A gene holds the instructions that forms the proteins in our bodies and these proteins are used for our traits and bodies.
1. Crust: The crust is mostly made of oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. Its temperature is about 500 °C (900 °F) to 1,000 °C (1,800 °F) ranging from depth.
2. Mantle: The mantle is mostly made of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals.
Its temperature is about 1000° Celsius (1832° Fahrenheit) near its boundary with the crust, to 3700° Celsius (6692° Fahrenheit) near its boundary with the core.
3. Outer Core: The outer core is mostly made of metals like iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth's magnetic field. The outer cores temperature is about 4400 °C (7952 °F) in the outer regions to 6100 °C (11012 °F)near the inner core.
4. Inner Core: The inner core is mostly made of iron and nickel, but 5 percent of it has been a mystery for a long time. This new study concludes that it's most likel. The inner cores temperature is about 6,000 C (about 10,800 F). That's as hot as the surface of the sun.
A chemical interaction is compelled by electrostatic forces which can occur both in vitro (studies are done outside living organisms), and in vivo (scientists conduct their studies with the use of whole living organisms). In simpler terms a chemical reaction is a change that occurs when two or more substances combine to form a new substance.
