Short Answer Questions
Directions: For each short answer question, please type your response
below the question.
1. Define the term homeostasis. Why is it important for the body to
maintain homeostasis? What happens if the body loses homeostasis?
Provide your answer here. Is the state of balance in your body. To ensure
that we live by adapting to external changes and prevent distrubtions that
could make you sick or even die. If we lose homestatis it could make us sick,
organ damage or failure or even death in some cases.
2. How do negative feedback loops help the body maintain homeostasis?
Discuss one example of a negative feedback loop in the body.
Provide your answer here. When negative feedback happens it start with the
receptor it senses the change around us then goes to the control center
which receives and uses this feed to determine apporiate response then goes
to the effector bu reacting to bring the
, body back to balance. Example body temp rises-we sweat-then body cools
off
3. What is diffusion? How does diffusion work to move materials across the
plasma membrane of a cell?
Provide your answer here. The movement of particles from an area of higher
concenteration to lower concentration this is due to some random
molecule motion. By allowing molecues to move from a high concentration
to low conce
