Ethylene is released fruit is ripening because of this ethylene fruit nearby will also ripen what type of feedback is this

a. negative
b. positive
c. partial
d. neutral

Hi!

The answer would be B. Positive

Explanation:

A positive feedback mechanism is that in which a stimulus induces an output which in turn functions to magnify the same response (acting as a stimulus to itself).

As in this case, Ethylene acts as a stimulus for fruit ripening (response). When it is released during fruit ripening, it stimulates nearby fruits to ripen (response), which in turn acts to stimulate further fruits to ripen (response), resulting in the effect being widespread (magnified)

Hope this helps!

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
