Skylab was the first space station.
The very first terrarium was created by Nathaniel Bagshaw Ward in the year of 1842. He was a botanist. He was interested in studying insect behaviour. Once he accidentally left one of his bug jars open. A fern spore in the jar sprouted, grew and germinated into a new plant. This is how the first terrarium had been created.
Because of the different conditions within, terrariums can be classified into two types: closed and open. Closed terrariums have a lid to enclose the plants entirely within the glass container. Open terrariums do not require a lid.
Answer: ATP- ADT-ADP is a cycle.
Explanation:
Adenosine triphosphate is like a charged battery and Adenosine diphosphate is a dead battery.
ATP is hydrolysed and the ADP and Pi is obtained by the addition of water and in response energy is released.
The ADP can be recharged as a battery and to get converted into ATP by the addition of the inorganic phosphate and this process releases energy and this cycle continues.
