Darina [25.2K]

Smoking have life-threatening effects on a smoker's lungs. A smoker is at a high risk of lung cancer and chronic obstructive pulmonary disease. In order for a coach to explain the destructive effects of smoking on the performance of the athletes, it is best to show a diagram of the flow of the oxygen-rich blood in a non-smoker's body and then the flow of blood with less-oxygen in smoker's body. This will show the difference between the two situations clearly, and show how the airway resistance effects the performance of a person.

Hence, the answer is 'option C - Diagram the flow of oxygen-rich blood in non-smoker's body and the, diagram of flow of blood with less oxygen in smoker's body'.

Explanation:

Las células procariotas son más primitivas que las eucariotas, por ende, sus estructuras son más simples. Las células procariotas están en organismos unicelulares tales como las bacterias, mientras que las células eucariotas están en organismos unicelulares y pluricelulares como en plantas, animales, u hongos. La diferencia más notoria entre ambos tipos de células es la ausencia de núcleo en las procariotas haciendo que el ADN está disperso en el citoplasma mientras que en las células eucariotas, el ADN está dentro del núcleo celular.
