Oxygen
Nitrogen

2-Ureters
3-Bladder
4-Urethra
A cell with an equal amount of solutes inside and outside of the cell is in a(n) ______ environment, while a cell with a higher concentration of solutes outside the cell is in a(n) _____ environment.
isotonic, hypertonic
isotonic, hypotonic
hypertonic, hypotonic
hypotonic, hypertonic
Using what you have learned about the prefixes, hypo-, hyper-, and iso-, which of the following would be the best explanation of a condition called hypothyroidism?
A condition where the thyroid gland produces enough of the hormone.
A condition where the thyroid gland produces too much of the hormone.
A condition where the thyroid gland stops working altogether.
A condition where the thyroid gland produces not enough of the hormone.
What was the purpose of using chemical indicators in the creation of the cell model?
to determine which substances were used
to determine which substances passed through the cell membrane
to determine which chemicals to avoid putting in your body
to determine where the cell membrane is located
A cell membrane is “selectively permeable” this means,
all cell membranes allow the same substances into the cell
a cell membrane regulates which molecules are able to pass in and out of the cell.
a cell membrane stops all molecules from entering the cell.
a cell membrane selectively determines at which times molecules can pass into the cell.
The inviting smells of homemade chili brings you into the kitchen from your bedroom. This is because the molecules in the chili have,
diffused across the house in a direct path to your room.
diffused across the house randomly
moved to an area of higher concentration.
used energy to become more ordered
In this type of diffusion, water is moved from an area of greater concentration to an area of lesser concentration.
osmosis
facilitated diffusion
active transport
concentration gradient
In this type of diffusion, cells use transport proteins and energy to move substances.
osmosis
facilitated diffusion
active transport
concentration gradient
In the gas exchange system, ____________ is moved from your lungs into the bloodstream, __________ is moved from bloodstream to lungs, then air.
oxygen, carbon dioxide
carbon dioxide, oxygen
nitrogen, oxygen
oxygen, nitrogen
The kidneys are a vital part of regulating
the gas exchange of oxygen and carbon dioxide throughout the body
blood, by filtering it to remove wastes
waste, by holding waste containing urine before it is released from the body
nutrients, by transporting them to cells throughout the body.
In the circulatory system, blood moves away from the heart through _________________ and returns to the heart through _________________. These are both types of _________________.
veins, arteries, vessels
arteries, vessels, veins
vessels, arteries, veins
arteries, veins, vessels
In the body, cells are within 0.01 mm of a capillary. Which of the following illustrate what is happening as the blood flows past these cells?
Blood flows into the cells, dissolving through the membrane of the cell
Oxygen, glucose and other substances move out of the blood into the cell
Carbon dioxide, glucose, and other substances move out of the blood into the cell
Cells with waste products are carried by the blood stream out of the body
The gas exchange system, circulatory system, and urinary system work to maintain the internal conditions of the body. Which of the following descriptions incorrectly explains how these systems function?
Oxygen from the lungs is moved to the bloodstream via the heart
Blood vessels network into smaller and smaller vessels until it reaches the capillaries
Blood is filtered to eliminate water, salts and wastes by the urinary system.
Exchanging materials across cell membranes occurs via diffusion, osmosis, facilitated diffusion and active transport
Imagine the waste from your cells moves out of your body like the waste from your home moves to the landfill. If the organs of the urinary system are not working properly, it is most like,
the trash at your home or apartment not being picked up
the trash building up in your kitchen garbage can.
the trash collector truck breaking down before it reaches the landfill
the trash in your home sorted into recyclables and non-recyclables
The kidneys play many important roles in the body. Which of the following is NOT performed by the kidneys?
regulate blood pressure and hydration
restore the balance of water and salts in the blood
filter blood to produce urine
convert ammonia to urea
The difference in the color of urine, very dark to very light, is due to
the amount of water that is reabsorbed by the kidney
the amount of water that is reabsorbed by the liver
the amount of water that is reabsorbed by the bloodstream
the amount of water that is reabsorbed by the nephrons
Sweating is another way waste moves out of cells. Which of the following best describes what happens?
The bloodstream carries excess salts which move out of the body as sweat
The bloodstream carries chemical waste which moves out of the body as sweat
The bloodstream carries carbon dioxide which moves out of the body as sweat
The bloodstream carries glucose which moves out of the body as sweat.
Eukaryote cells are distinguished by what characteristic?
have a nucleus in their cells
do not have a nucleus in their cells
are multicellular
are uni-cellular
The filtering unit of the urinary systems is?
lungs
kidney
blood
liver
The microscopic sacs in the gas exchange system are called
lungs
heart
alveoli
arteries
A substance that increases the amount of urine produced is called a?
diuretic
anti-depressant
hypotonic
ventricles
A cell which gains mass when placed in a solution is said to be in a _________________ environment.
hypertonic
hypotonic
isotonic
tonic
Diffusion and osmosis preserve the health of the cell by maintaining
homeostasis
energy
measurements
selectivity
The diagram above shows the beginning of an experiment. Which statement best describes the probable results of this experiment?
The water in the beaker will turn blue because the starch will move out of the bag into the beaker.
The contents of the bag will turn blue because the iodine will move out of the beaker into the bag.
The bag will shrink in size because water will move out of the bag into the beaker.
The contents of the beaker and the contents of the bag will eventually reach equilibrium.
Diffusion is the movement of molecules from—
an area of low concentration to an area of high concentration.
an area of high concentration to an area of low concentration.
an area of low concentration to high concentration using energy.
an area of high concentration to low concentration using energy.
Examine the figure above. Which statement is correct?
The cell in beaker A will shrink due to a lower concentration of solvent outside the cell.
The cell in beaker B will shrink due to a higher concentration of solvent outside the cell.
The cell in beaker A will swell due to a higher concentration of solvent outside the cell.
The cell in beaker C will swell due to a lower concentration of solvent outside the cell.
If eggs from the saltwater fish shown above are placed into a beaker of distilled water, what will happen to the eggs?
they will swell and burst because water will move into the eggs
they will shrink because water will move out of the eggs
they will stay the same because water will move equally in and out
they will stay the same because the water will not move in or out
