10 Questions
Which type of regulation involves a self-adjusting mechanism to maintain stability, balance, or equilibrium within a cell or the body?
Negative feedback regulation
What type of regulation involves the release of hormones into the blood controlled by a stimulus?
Negative feedback regulation
Which mechanism of regulation involves continuous adjustments to meet the 'Set Point'?
Negative feedback regulation
What type of regulation requires adjustments of conditions when changes occur inside and outside the system?
Negative feedback regulation
Which type of regulation involves stability, balance, or equilibrium within a cell or the body?
Negative feedback regulation
Which of the following is an example of positive feedback regulation in biological systems?
Lactation (milk production)
In osmoregulation, what happens when [solutes] increases above normal in the extracellular fluid?
Intracellular fluid moves to extracellular surface causing cell shrinkage
What is the most common feedback loop in the biological system and acts to reverse the direction of change to maintain the set point?
Negative feedback regulation
What ensures a balance of water and solutes across cell membranes for optimal functioning of biochemical processes?
Osmosis
Which condition will result in the death of cells during osmoregulation?
[Solutes] decreases in the extracellular fluid, causing extracellular fluid to move into cells and swelling
Test your knowledge of negative and positive feedback regulation mechanisms in biological systems, including osmoregulation, thermoregulation, and hormonal regulation. Understand how positive feedback regulation acts to speed up the direction of change with examples such as lactation and milk production.
