Question

question 5
blood clotting
when a part of the body is injured, it releases chemicals that activate blood platelets. platelets are responsible for stopping bleeding by forming clots. an activated platelet, in turn, activates more platelets, which group together to form a blood clot.
question: was the stimulus increased or decreased?
the stimulus was decreased.
the stimulus was increased.
the stimulus stayed the same

Explanation:

When the body is injured, chemicals are released to activate platelets for clot - formation to stop bleeding. As more platelets are activated and clots form, the bleeding (the initial stimulus) is reduced. So the stimulus is decreased.

Answer:

The stimulus was decreased.
