Answer:

C

Explanation:

Iodine is used to test for starches. When iodine is placed in a solution with starch (non-reducing sugars) it turns blue-black color. When amylase, a starch, is mixed with saliva, it is ‘digested’ to glucose, a reducing sugar (the brown colour of the aqueous solution remains).

Which of the following statements correctly describes the relation between frequency, wavelength energy and velocity of a wave t
Sedbober [7]

The statement that correctly describes the relation in the question is ; ( A ) As wavelength decreases, frequency increases, energy increases and the speed remains the same.

The Frequency of a wave travelling in a medium is directly proportional to the energy produced by the wave and inversely proportional to the wavelength of the wave.  

Changes in the wavelength and frequency of a wave has no effect on the wave speed. but has an effect on the energy produced by the wave. therefore the wave speed remains constant regardless of the changes in wavelength and frequency

Hence we can conclude that   As wavelength decreases, frequency increases, energy increases and the speed remains the same.

The administration method that takes the longest time for the drug to reach the brain is __________.
photoshop1234 [79]

Oral ingestion or swallowing is the administration method that takes the longest time for the drug to reach the brain. When using this method, the drug is swallowed through the mouth, moves to the stomach and then into the bloodstream before it can be transported to the brain. This means that it takes longer for a swallowed drug to start functioning than it does with other methods of administration such as injecting.
