A.so that the experiment is cheaper and easier to conduct
b.so that a specific problem can be solved as quickly as possible
c. so that no one else will know what is being studied
d. so that they respond to the test as they would normal conditions
The maximum probable speed of walking is restricted mainly by two factors, that is, the length of the leg and the free fall acceleration. The animals with longer legs exhibit higher maximum walking speed, while the animals with very short legs exhibit low maximum walking speed.
The large birds like pheasants usually walk brief distances, however, birds like chickadees never walk. In the case of pheasants, they exhibit a higher maximum walking speed, on the other hand, the chickadees exhibits a low maximum walking speed. Thus, the chickadees should never walk, they should fly or hop.
Also, more energy is utilized in flying than in walking. Therefore, large birds like pheasants usually walk brief distances so that energy can be saved.
Answer: D. helps in digestion
Explanation: Gastric juice in the stomach contains HCL which creates an acidic condition(pH1.5-2.0) which is optimal for the action of enzymes in the stomach. HCL stops the activity of salivary amylase & helps to kill bacteria in food. It doesn’t help in digestion cuz it is not an enzyme.
