Answer:
Element.
General Formulas and Concepts:
<u>Chemistry</u>
- Reading a Periodic Table
- Diatomic Elements
Explanation:
Diatomic Elements are elements that are bonded to themselves. Naturally, these elements are not found alone in nature.
Diatomic Elements:
Hydrogen
Nitrogen
Oxygen
Fluorine
Chlorine
Bromine
Iodine
Since Nitrogen is a diatomic element, we would find Nitrogen in nature as N₂.
Answer:
Option A, Tectonic plates above the currents move toward each other.
Option C, One plate will submerge beneath another plate.
Option D, A convergent boundary is formed at the site of the collision.
Explanation:
The convection currents are the ones responsible for the movement of the tectonic plates, thus shaping the Earth's appearance with their movement, as well with the structures created by the movement. If the convection currents move toward each other, than the tectonic plates are moving toward each other. That will cause collision between the continents, and convergent boundaries will be formed. If the collision is between two or more continental plates, than they will merge, and from the pressure mountain ranges will start to form, but if there an oceanic plate involved as well, than the oceanic plate will be subducting beneath the continental plate or plates.
Answer:
Decomposition reaction
Explanation:
2NO —> O2 + N2
The above equation clearly indicates decomposition because a single reactant (NO) produces two products (O2 and N2). Decomposition reaction is a reaction in which a single compound breaks down into two or more elements or compound as seen in the equation above.
Answer: E. they enable enzymes to bind to their substrates.
Explanation:
The cofactors are the molecules that help the enzyme catalyze the reactions. The Cofactor can be defined as a non-protein chemical compound that either loosely or tightly binds to the enzyme. This facilitates in performing the reactions that enzyme cannot perform alone. They can be divided into prosthetic group and coenzymes. The cofactors enhances the binding affinity of the enzymes with their substrates so that products can be formed.
The ligaments, tendons, and muscles of the knee prevent it from hyperextending or bending backwards. Most notably, the posterior cruciate ligament (PCL) prevents the knee from hyperextending by connecting the femur (thigh bone) to the tibia (shin bone).
