blondinia [14]

Answer:

The resistance of the device is 27Ω

Explanation:

When a device is used in a circuit in which the voltage is 81 V, the current flowing through the device is 3 A.

In order to calculate the resistance of the device, we know that the resistance is directly proportional to the voltage in the terminals of the device and the current flowing through it.

Using Ohm's law

R=\frac{V}{I} \\R=\frac{81V}{3A}=27Ω

Which carbohydrates are found in our genetic material?
Kisachek [45]

The carbohydrates found in our genetic material are the two sugars deoxyribose and ribose.

Carbohydrates are defined as organic compounds which occur in food and living tissue and include starch, sugars and cellulose. They are composed of hydrogen, oxygen and carbon.

Deoxyribose is a sugar found in the structure of DNA, while the sugar ribose is found in the structure of RNA.

DNA is the molecule that carries the cell's genetic information while RNA is the molecule involved in synthesis of protein using the coded information received from DNA.

Both DNA and RNA are termed as the genetic molecules of life.
