Answer:
7 days.
Explanation:
In 7 days the moon will be in its last quarter phase. In the last quarter phase, the half part of the moon is illuminated and the other half is hide in darkness. The illumination of the sides of the moon provide information about the dates of the month. Last quarter phase is also called third phase of the moon. In this phase, the Moon is in quadrature and has the elongation of 270 degree. It is also the indication that the half cycle of the moon is completed and the other half is started.
 
        
             
        
        
        
Answer:
38 ATP
Explanation:
On complete oxidation of one molecule of glucose yields 38 ATP.  Break up of energy production is given below:  
- During glycolysis 2 ATP and 2 NADH is produced.
- During formation of Acetyl CoA, 2 NADH is produced.  
- During Citric Acid Cycle, 2 ATP, 6 NADH, 2 FADH₂ are produced.  
Finally during Electron transport chain, reduced coenzymes NADH and FADH₂ oxidised to release ATP. Each NADH produce 3ATP and each FADH₂ produces 2 ATP. Altogether 10 NADH is produced during entire process of cellular respiration which yield 30 ATP and 2 FADH₂ yields 4 ATP. Therefore, on complete oxidation of one molecule of glucose yields 38 ATP.
 
        
                    
             
        
        
        
Medications can be tested on cell cultures instead of being injected into patients unnecessarily.
Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells.
 
        
                    
             
        
        
        
Answer:
The correct answer is A. Since the Earth has a tilted angle of 23.5 degrees as it moves around the sun, the amount of sunlight that is received by the hemispheres vary from time to time. This is mainly responsible for the changes in the temperature and daylight hours, which are the indicators of the changes in seasons.
In this case, when one hemisphere of the Earth is tilted toward the sun, it receives more sunlight than the other end. Therefore, this region experiences summer, wherein the daylight is longer and the temperature is warmer
