Answer:
True.
Explanation:
Enkephalins and endorphins are endogenous peptides while morphine is an exogenous peptide.
Enkephalins and endorphins are powerful analgesics 18 to 500 times more than morphine. Hence, morphine is less analgesic than enkephalins and endorphins.
Enkephalins and endorphins act on the  mu, kappa , delta receptors and morphine also acts on the same receptors. All of them has same effects on the body.
Hence, Enkephalins and endorphins are peptides that act like morphine.
 
        
                    
             
        
        
        
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.
 
        
             
        
        
        
Answer:
Factor  Analysis
Explanation:
Factor Analysis is a statistical procedure that can be used to identify clusters of behaviors (such as verbal skills, intelligence) that are related to a trait. 
Factor analysis helps to accumulate a lot of data in many variables into a few variables which can be used for further analysis or study. The aim of factor analysis is to aggregate individual behaviors into a minimized number of factors.
