1.a, 2.b, 3. c, 4. c, 5. c
Explanation:
1.
4H+O2→2H2O
2.
They must have two or more reactants.
3.
The reaction has more than one product.
4.
S + O2→SO2
5.

Answer:
because they have different genes
Explanation:
when animals mate or reproduce the parents share each other genes to make thr offspring when that accurse different beetles can have different genes that could code for longer horns or shorter. Their could also be a mutation.
I would say the answer is transport work!
Substances can go through the cell membrane through active and passive transport! Active transport is powered by adenosine triphosphate, ATP!
Cellular respiration input: pyruvate (partially oxidized glucose), ADP, and inorganic phosphorus. Output: ATP, carbon dioxide, and water. Photosynthesis input: water, carbon dioxide, and photon energy. Output: Oxygen and glucose.
Answer:Sunlight bounces off the surface of the lake. --Reflection
Sunlight shines on the beach and transfers heat to the sand. --Absorbtion
Waves of light are bent as they shine through the water to the lake bottom.--Refraction
Explanation: light occurs as beams which are made up of rays.
During reflection, light is re-emitted or through back from surfaces.it responsible for our ability to see things around us. Mirrors works on the principle of reflection
During refraction the direction of the wave changes as it travels from one medium to another of different optical density.in this case, light is passing from air to water,which are two media with different optical density.this change in media causes a bending of the light rays. This is the reason a stick placed a water may seem bent.
Sunlight carries heat .heat is a form of energy that moves as a result of temperature difference.heat from sunlight moves through the atmosphere without a material medium. Then it is absorbed by the particles of objects
