How can scientists know for sure that the cell theory is true? What evidence do we have to prove it?

Akimi4 [234]

I agree with it.The most widely accepted theory is that the first cells were created by groups of molecules working together to make the basic biomolecules (Carbs, Lipids, Proteins, Nucleic Acids). These biomolecules eventually found each other and supported each other creating cells. Over millions of years these unicellular organisms evolved into multicellular organisms, eventually leading up to humans and other common life forms today.

How many electrons pass through a 20-ohms resistor in 10 min if there is a potential drop of 30 volts across it?

tangare [24]

The number of electrons passes through 20 ohms resistor in 10 minutes is 5.625e+21.

<h3>What is a resistor?</h3>

In an electronic circuit, a resistor is an electrical component that limits or regulates the flow of electrical current.

Given, the resistance is 20 ohms.

The potential difference is 30 volts

Time is 10 minute

By the formula of current

$\rm I = \dfrac{30}{20} = 1.5 \;C/s$
