Which of the devices described below is an example of one that uses DIGITAL technology?

1. A record album stores sound information in physical grooves

2. A clock displays time information by the position of its "hands"

3. A cell phone converts sounds to numerical data and sends it

4. A thermometer shows temperature based on the height of a column of mercury

3. A cell phone converts sounds to numerical data and sends it

Explanation:

Digital technology are electronic device that has the ability to store data, process data and transfer the day as information. It allows large information to be stored up in a small device

A cell phone is an example of electronic device that has the ability to receive and process data.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
