<span>First, we need to clarify what negative feedback means. Negative feedback is a response that is fed back to the input and that tends to reduce the fluctuation of the output. Negative tries to confer stability to the system. So, you can see that the option B. cannot be because if you add more wood to a fire the fire will increase instead of extinguish. The option A implies a signal (from the high temperature) that starts the air conditioner, so it brings the system out of the equilibrium. The option C. indeed signals that the "full" signal es fed back and the organism will stop eating and so it reaches equilibrium. The answer is the option C. not eating any more when you are full.</span><span />
Answer:
The correct answer is - strata spinosum and strata basale.
Explanation:
The two strata of epidermis that are prone to the cancer are stratum basale and stratum spinosum. The stratum basale is the major stratum layer as it is only layer that can divide and mitotically active.
The other major layer that is succeptible to cancer is spinosum as it allows the maturation of the keratinocytes. The major culprit is UV light, however other causes such as radiation and arsenic can also cause cancer.
Thus, the correct answer is - strata spinosum and strata basale.
