Homeostasis in the human body is often maintained by a:

neutral feedback loop

solar feedback loop

positive feedback loop

negative feedback loop

Cells can function

at any temperature and pH.

only in a narrow range of temperature and pH.

in rapidly changing temperatures and pHs.

in a wide range of pHs and temperatures.

Organisms must be able to adapt to a changing external and internal environment. An organism's ability to maintain a stable internal environment is known as homeostasis. How does a cell's membrane help an organism maintain homeostasis?

Cell membranes directly control the temperature of the cell.

Cell membranes control the substances that enter or leave cells.

Cell membranes use a large portion of the cell's energy supply.

Cell membranes protect the cell organelles from large doses of radiation.

Select the correct statement about the process of homeostasis?

Controls and coordinates body activities through chemical

controls and coordinates body activities through electrical impulses

For maintenance of a steady state in the internal environment

remove metabolic waste products from the cel

Difficulty regulating insulin can lead to which disease?

Heart Disease

Alzheimer's Disease

Diabetes

Kidney Disease

chemical made by glands that tell cells to make something or respond in some way.

acid

enzyme

perspiration

hormone

How does the body balance blood sugar levels when glucose gets too high?

Sweating

Shivering

Filtering in the kidneys

Producing more insulin

Rapid growth during puberty causes your body to release more and more growth hormones. As you grow, more and more growth hormones are released until puberty is reached, and then the hormones stop.

What is the function of insulin?

diagnose diabetes

turn glucose into energy

allow cells and organs to use glucose

all choices

10.

What are the 2 main problems associated with all diabetes patients?

type 1 and 2

mood swings and increased hunger

high and low blood sugar

11.

What type of diabetes is characterized by insulin resistance?

Type I

Type II

Prediabetes

Gestational diabetes

12.

High blood sugar levels after a meal usually stimulate

Glucagon release from the liver

Glucagon release from the pancreas

Insulin release from the liver

Insulin release from the pancreas

13.

The group of organisms that use the process of homeostasis includes

mammals, only

animals, only

plants and animals

all living things

14.

Why does pulse rate increase during exercise?

Oxygen and carbon dioxide must be removed from the body ASAP

Gas exchange adjusts to happen more quickly than when a person is at rest

Oxygen must be moved to the lungs and carbon dioxide must be moved to cells more quickly

Carbon dioxide must be moved to the kidneys to be excreted

15.

Which of the following is most likely to cause a person's blood cells to burst?

eating many salty foods

eating many greasy foods

drinking small amounts of water

drinking very large amounts of water

16.

Which system sends electrical messages that helps control the body's responses to internal and external changes?

nervous

endocrine

reproductive

integumentary

17.

What hormone is produced in the pancreas that lowers blood sugar?

Insulin

Glucagon

Ketones

Glucose

18.

These two body systems regulate feedback mechanisms.

Skeletal & Muscular

19.

What is an example of a positive feedback mechanism?

20.

If the calcium in your blood decreases below homeostasis levels, a gland in the brain will sense the decrease and send a chemical message to your bones. Your bones will release calcium into the blood, bringing blood calcium levels back up.
