Answer:
option A is correct 
Explanation:
when atoms in the solid state are heated they gain energy and start vibration due to which  solid molecule lose their rigidity and are converted into liquid by the gain of energy
 
        
             
        
        
        
Answer:
Forest floor
Explanation:
Tropical rainforest is characterized by high rainfall that allows a diverse growth of plant species. The different species of plants and animals species that make up a rainforest are found in different layers. There are four layers or sections in the rainforest from top to bottom viz: emergent layer, canopy, understory and forest floor. 
Since the layers are classified from top to bottom, each layer receives different amount of rainfall and sunlight. According to the question, the FOREST FLOOR receives the least amount of sunlight making it the darkest section of the rainforest. Due to the inhibited penetration of sunlight into this layer, it usually does not support any plant growth.
 
        
             
        
        
        
Osmosis is the diffusion of water across a semi-permeable (or differentially permeable or selectively permeable) membrane. The cell membrane, along with such things as dialysis tubing and cellulose acetate sausage casing, is such a membrane. The presence of a solute decreases the water potential of a substance.
        
                    
             
        
        
        
Answer:
Explanation:
We are being provided with little information about the question in the study.
The 50 ml is required to make an unknown solution which has a mass of 5g, 
SO, we are to determine the amount of grams that will be needed to make the product.
We are not given information about the product, as such this will be difficult and impossible to answer.
You can add the additional information required in the comment section below and further explanation and the detailed solution will be provided.

Answer:
After a motion is proposed, if the motion requires a second and none is immediately offered, the chair of the body will usually ask, "Is there a second?" If no second is obtained within a few moments of proposing the motion, then the motion is not considered by the assembly, and is treated as though it was never offered. Such a motion may be introduced again at any later time.
