The ability of an organism to maintain a stable internal environment.
What is homeostasis?
This is the endocrine gland responsible for releasing hormones to regulate blood sugar.
What is the pancreas?
To maintain homeostasis, your body may do this as part of the cooling response.
What is sweating or dilating your blood vessels?
Which reproduces faster, prokaryotic cells or eukaryotic cells?
What is prokaryotic
Disrupts homeostasis
What is disease or illness?
This hormone is released after meals to lower blood sugar levels.
What is insulin?
To maintain homeostasis, your body may do this as part of the warming response.
What is shivering, goosebumps, or constricting your blood vessels?
Describe the role of the Nucleus
Controls the functions of the cell
Three aspects of the body that must be maintained in order to achieve homeostasis.
What is pH, Body Temperature, and Blood Sugar?
This hormone is released in between meals to raise blood glucose levels.
What is glucagon?
For these organisms, organelles help to regulate homeostasis by responding to the external environment.
What are unicellular organisms?
Where is the DNA in a eukaryotic cell located?
What is in the nucleus
cells function in only a narrow range of what two body "conditions"
What is temperature & pH
Blood sugar levels rise and fall throughout the day because signals are sent due to this mechanism.
What is a feedback mechanism or loop?
In extreme cold, the body may shut off blood flow to limbs in order to protect the temperature of these.
What are vital organs?
What type of cell is complex and has many organelles
What is eukaryotic
Excess glucose is stored as glycogen in these cells.
What are liver and fat cells?
This is the part of the brain responsible for sensing changes in the body’s temperature and adjusting to maintain homeostasis.
What is the hypothalamus?
long twisted molecule found floating around in the cytoplasm. Also known as genetic material.
What is DNA?
