Explanation:
Answer:
b. Works within an upper and lower range
c. " Is regulatory. "
d. Is very common in biological systems
Explanation:
Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.
For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.
Answer:
C) The percentage of pink flowers should increase over time.
Explanation:
According to the given information, the plants with pink flowers are able to reproduce more but are also have higher rates of herbivores as the slugs preferably eat the pink-flowered plants.
If slugs are removed from the system, the plants with pink flowers would have an absolute reproductive advantage over the plants with white flowers. This would increase the frequency of plants with pink flowers as they exhibit reproductive success over the plants with white flowers.
