Answer:
The earth has different layers because as it formed, the lighter parts (like continental crust) floated to the surface, and the really heavy parts (like iron and nickel in the core) sank to the middle. It is just like when you mix oil and water: the oil will float to the surface because it is lighter (or less dense) than the water.
The correct answer here is C. A molecule that has both polar and
nonpolar regions is called ampipathic. The polar end of the molecule is
water-loving, or hydrophilic, and the nonpolar end of the molecule will
be water-repelling, or hydrophobic. This means the molecules are able to
connect both to other water molecules, and to molecules of other
substances.
This is a multi step process with multiple enzymes acting but the most basic answer would be DNA Polymerase.
Answer:
The process of photosynthesis converts light energy into stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen. ... As matter and energy flow through different organizational levels of living systems, chemical elements are recombined in different ways to form different products.
Explanation:
A homogeneous mixture of two or more substances is called a solution.
