Biology

saw5 [17]3 years ago
4 0

A change in which no new substance is formed is called a physical change.

Examples: Crushing a can, Melting an ice cube, Boiling water, Breaking glass, Dissolving sugar in water, Shredding paper, and Chopping wood.

All of these examples may involve a change in shape, form, or appearance, but it DOES NOT involve a change in the molecule structure.

Negative feedback
zhuklara [117]

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.
