Answer:
The correct answer is - less efficient signaling.
Explanation:
Second messengers are the molecules that help in transferring the information in the form of intracellular signal that has come from external stimulus.
Second messenger molecules should be short-lived as the concentration of these molecules should be decreased fastly so the cell can be available for other stimuli mediated by the same second messenger.
With increased lifetime, signaling will be less efficient as another stimulus cannot be detected.
Thus, the correct answer is - less efficient signaling.
Answer: Sugar and oxygen
Explanation:
The producers are plants that use carbon dioxide and water to convert it glucose. During this process not only glucose is produced, oxygen is also released into the atmosphere as a by-product of this process.
The Oxygen that is released into the environment is the excess oxygen that is not used by the plants for the process of cellular respiration.
The glucose that is made by the plants is used in this form, it is converted into adenosine tri phosphate for the plants to use.
Hence, the correct options are sugar and oxygen.
