Answer:
<em>Read explanation.</em>
Explanation:
Well, because it plays such an important role in problem solving. Science is all about solving the problems, puzzles and riddles of this world and universe, and to do that, we elaborated something called the scientific method.
The scientific method is a method we follow to encounter, solve and understand certain problems. A famous example would be the "broken torch example":
Torch doesn't work → is it the batteries? → we try replacing the batteries
↓
or is it the circuit?
↓
we have concluded that it is not the batteries
↓
we try finding the problem in the circuit
↓
etc.
As you can see, in the example, the 2 possible problems that would explain why the torch isn't working, are our 2 hypothesis.

Chloroplasts;
These contain grana, the site of the light-dependent reaction of photosynthesis, and stroma, a fluid substance that is the equivalent of cytoplasm in cells, which is the site of the light-independent reaction of photosynthesis. Grana are structures made of stacked thylakoid membranes, necessary for chemiosmosis, connected to one another by lamellae.
Only bacteria can reproduce outside a host and bacteria are not dependent on a host
Answer:
Chemical properties are very useful in identifying substances. However, unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance.
