Answer:
The correct answer - The Gas giants are much much larger in size.
Explanation:
There are two distinct types of planets that are four rocky planets and four gas giants plants. Mercury, Venus, Earth, and Mars are four rocky planets, and Neptune, Uranus, Saturn, and Jupiter are four gas giants.
The Gas giants plants are much much larger in size in comparison to the rocky planets. It is because rocky planets have relatively low gravity than gas giants and were not able to attract large amounts of gas to their atmospheres.
Thus, the correct answer - The Gas giants are much much larger in size.
 
        
                    
             
        
        
        
The cycle runs like this: 
Deoxygenated blood enters from the body to the heart via the superior/inferior vena cava. It goes directly to the right atrium and down to the right ventricle. From there it'll pass through the pulmonary artery into the lungs where diffusion will happen in the capillaries. Gas exchanges will occur and the blood will become oxygenated and return to the heart via the pulmonary vein. From the pulmonary vein it will enter back into the left atrium and then will give the final pump of oxygen rich blood into the aorta and then into the entire body.
 
        
             
        
        
        
Higher phosphates is typically associated with a large amount of organic material in a water supply. A large amount of organic material implies rapid growth, so higher phosphates is the only feasible choice. 
        
             
        
        
        
A fossil would from through mineral replacement by replacing the existing material of the animals bones with minerals, to become petrified. The Minerals will keep the fossil preserved longer.
Have a good day!!
