Why cannot sound travel through outer space?

Sound needs an atmosphere to travel around and everyone knows space ain't got an atmosphere, also the speed of sound is 340 metres per second through the air. it travels so much faster on water or solids, but in a vacuum like space there is no matter for the sound to travel through.

hope this helps you good luck

How can the proteins be used to increase the amount of oil produced by a plant?

Explanation:

Here, the main discovery was the function of these proteins in plants. They regulate the production of fatty acids which in turn are part of plant fats and oils. Since the discovery was related to this function of proteins further investigations should be around it. Out of all the given options only the last question directly tackles the function of these proteins. It talks about altering their activity to increase the amount of oil produced by plants. This can be commercially helpful since many of these oils are used for cooking or in other products like essential oils. Rest of the questions like "are plants non renewable source" or "how are proteins produced" are general questions which can be asked even in the absence of this discovery.
