I would say 4. To create a hypothesis, you would need some knowledge about what you're studying. This is where prior knowledge could come in handy.
Answer:
Triacylglycerols are acylglycerols with three fatty acid molecules, generally long chain, which can be the same or different; we speak of simple triacylglycerols when there is the same fatty acid in all three glycerol positions, but most are mixed triacylglycerols, with at least two different fatty acids. The properties of triacylglycerols will depend on the type of fatty acids they contain.
Most of the fats and oils of both animal origin (tallow, butter) and vegetable (olive, corn, sunflower, palm, and coconut oils) are formed almost exclusively by triacylglycerols.
Physiologically, triacylglycerols are an important energy reserve. In most eukaryotic cells, triacylglycerols are stored in the cytosol as microscopic fat droplets. In vertebrates there are specialized cells in the storage of fat, adipocytes. In humans, the presence of fatty tissue under the skin, in the abdominal cavity and in the mammary gland stands out.
A theory is a hypothesis that someone had but has not proven it.
A law is something that is proved.
Example: Sir Issac Newton had a theory on gravity he sat under a tree and then had a conclusion.
Answer:
The cone releases the seeds, and they float in the wind until they reach the ground where they can germinate and grow. Some do not produce seeds, instead they use spores to reproduce.
Ex. of Spore producing plants include: mosses and ferns
