What are the four components of a human organism?
cells, tissues, organs, systems.
What is a cell?
A cell is the basic structural and functional unit of all living organisms.
What is tissue?
Tissue is a group of cells that work together to perform a specific function in the body.
What is an organ?
An organ is a group of tissues that work together to perform a specific function in the body.
What is a system?
A system is a group of organs that work together to perform complex functions in the body.
What is homeostasis?
Homeostasis is the process by which biological systems maintain a stable internal environment despite external changes.
What is a negative feedback loop
A negative feedback loop is a biological mechanism where a change in a physiological variable triggers a response that counteracts that change, helping to maintain homeostasis.
What is a positive feedback loop?
A positive feedback loop is a biological mechanism where a change in a physiological variable triggers a response that enhances that change, leading to an amplification of the initial effect.
What is an example of a negative feedback loop?
An example of a negative feedback loop is the regulation of body temperature in humans, where an increase in body temperature triggers mechanisms to cool the body, such as sweating.
