I believe that B is the answer. There are actually multiple disadvantages to using solar energy including the lack of reliablility, the amount of resources needing to be used to create solar panels, and even the lack of energy when there is no sun.
The reduced dependence on fossil fuels is an advantage and the same is involved when it comes to choice C. It is also important for it to become a renewable source so there isn't a lack of needed resources.
The function of the semi permeable membrane is to allow substances to diffuse (transport) across it, because its only semi permeable the substance are able to cross. If it was a non permeable membrane it wouldn't allow the transport of substances.
Answer:
water
Explanation:
because the surface of water is slippery
Answer:
Yes, there would be no sugars present in any of the solutions as no colour change was depicted.
Explanation:
Benedict's solutions can be described as a solution comprising of copper(II) sulphate, sodium carbonate and sodium citrate. This reagent is used for testing the presence of carbohydrates or reducing sugars in a solution.
A series of colour changes is seen in the Benedict's test if a solution has sugars present in it. Initially, the colour is changed from blue to green, then orange/yellow. And in the end, the solution acquires a brick red colour.
In the scenario discussed in the question, no colour change is depicted in any of the test tubes. Hence, there would be no sugar present any of the solutions.
