35 grasshoppers/10 square meters has the highest population density.
 
- The highest population density of grasshoppers is 35 grasshoppers/10 square meters because more number of organisms are present in less area as compared to other population density.
-  In the option i.e. 40 grasshoppers/20 square meters and 50 grasshoppers/30 square meters have more number of organisms but the area is also greater.
- And we know that high population density means more number of organisms in less area so we can conclude that 35 grasshoppers/10 square meters has the highest population density.

Answer:
Glucose
Explanation:
The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.
Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.  
Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.  
The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.
Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.

Volumes.
If you put equivalent volumes in a bag, where both weigh the same, the density might get equal.
