Here are my quick example slides:

1st Picture:
just a title page

2nd Picture:
I just gave the definition of an organelle you could go more in-depth. The picture doesn't have to be there, of course.

3rd Picture:
Examples of organelles in plant and animal cells, these are just examples of how I would do one.

This was just to show how you could do it because it would be kind of hard for me to explain just in words.

Hope I could help! c:

What is the frequency of a 4,600 cm wave?
ddd [48]

The frequency of a 4,600 cm wave is 652 Hz

Frequency is the number of waves that pass a fixed point in unit time

Here given data is

Wave =  4,600 cm = 4.6 × 10⁸ nm

We have to calculated frequency = ?

Frequency =v = c/λ

Frequency = 3×10⁸m / 4.6 × 10⁸ nm

Frequency = 652 Hz

The combustion of ethanol ( C 2 H 6 O) produces
Mrrafil [7]

Explanation:

The combustion of ethanol is best represented by the equation below:

                C₂H₅OH + 3O₂   →   2CO₂   +   3H₂O    +   heat

Combustion process is very common among hydrocarbons.

Ethanol is an alcohol and in the presence of oxygen it will combust.

In combustion heat energy is always released into the environment.

     C₂H₅OH + 3O₂   →   2CO₂   +   3H₂O    +   heat

We see that ethanol combines with oxygen to give carbon dioxide and water in the reaction above.

The heat produced signifies that the reaction is exothermic in nature.

Excitation and relaxation of electrons in what element are responsible for most of the light reaching Earth from the Sun? A) Arg
vfiekz [6]
The answer here is B: Helium.

As many stars, the sun is largely composed of hydrogen and helium. The sun is able to give off radiant energy through the nuclear fusion process. This involves the process by which hydrogen isotopes fuses to create one helium atom and then creates radiant energy that travels to Earth.
