Homeostasis in Humans

what is the function of control centre? 

• Process message and sends response message to effector

• Produce a respond to bring back factor value to normal condition

• Regulation of chemical and physical factors

• detects changes in stimulus and send message to control centre

which of this NOT the important of maintaining homeostasis?

• to ensure optimal conditions for cellular activities

• Enables organisms to survive in extreme conditions

• Allows enzyme-catalysed reactions to function optimally

• Allow organism to carry out metabolic activity on their wish

Hey there, science explorers! Can you help Harper figure out what homeostasis means?

• The process of maintaining a stable internal environment

• The process of maintaining a stable environment

• Keeping your temperature at a set point

• Receptors sensing changes in your body

Answer explanation

Homeostasis refers specifically to the process of maintaining a stable internal environment, which is crucial for the proper functioning of organisms. The other options do not fully capture this definition.

During a fun science class, Olivia asked, 'Which hormone is the superhero responsible for lowering blood glucose levels?'

• Glucagon

• Insulin

• Adrenaline

• Cortisol

Answer explanation

Insulin is the hormone primarily responsible for lowering blood glucose levels by facilitating the uptake of glucose into cells, thus reducing blood sugar levels. Glucagon, adrenaline, and cortisol have the opposite effect.
