Answer:
The correct answer will be option- Increase in cAMP
Explanation:
Epinephrine is the hormone which is secreted during the stress conditions which prepares the body for fight or flight response. The epinephrine for flight activates the cAMP pathway in the muscles which leads to the activation of glycogenolysis process.
The epinephrine hormone binds the receptors in the muscles which convert ATP to cAMP. The cAMP bind to inactive PKA and activate it. The activated PKA converts the Phosphorylase b which activate the glycogen phosphorylase a which converts the glycogen to glucose 6 phosphate.
Thus, option- Increase in cAMP is the correct answer.

Explanation:
Answer: Option A
Explanation:
A tunicate is marine invertebrate animal which is a part of chordates. They have notochords and dorsal nerve chord. The subphylum of the organism is called as Urochordata.
The adult urochordates lack notochord but the larval stage of the urochordates have notochord. This is because it helps in swimming of the organism which is required only at the larval stage.
The adult stage of the tunicates is sessile and they do not swim so they do not require notochord.
