At the end the energy of the system is the same as 200 J.
<u>Explanation:</u>
It is a closed complex system and it has 200 J of energy.
Here the system is converting from one form to another form and then to another form.
As we know that there is a conservation of energy when one form is converted to another form without losing or gaining energy, whereas it may convert from one form to another form with the energy being conserved.
So after there is a conversion of one form to another form but there is no loss or gain of energy and same energy must be retained.
The correct option is D.
Alchemists are early chemical scientists, who first delved into the subject of chemistry. These early scientists were able to study the characteristics of common elements, the features of compounds and some of the laboratory methods that they developed then were found useful by later scientists. One thing that alchemists are known for is their quest to turn lead into gold.
Answer:
Stomata and guard cells facilitate this job of gas exchange in plants. Here, the guard cells are parenchyma cells, and they are the cells that surround stomata. Guard cells control transpiration, which is an essential process of plants that keep plants healthy.
