(deoxyribonucleic acid) A self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information. Located in the nucleus of eukaryotic cells.
Science dealing with the study of living organisms
A group separated from the rest of the experiment where the independent variable being tested cannot influence the results
Take a Break
Process by which organisms maintain a relatively stable internal environment.
Chemical reactions in living organisms that are necessary to maintain life
An experiment in which only one variable is manipulated at a time.
A conclusion one can draw from the presented details
A hypothesis that has been tested with a significant amount of data. Is usually agreed upon in the science community
Microscope that allows light to pass through a specimen and uses two lenses to form an image.
a microscope with high magnification and resolution, employing electron beams in place of light and using electron lenses.
Make appear larger than it is, usually with a lens or microscope.
A substance that speeds up the rate of a chemical reaction.
A type of protein that speeds up a chemical reaction in a living thing
The part of an enzyme or antibody where the chemical reaction occurs.
A compound or molecule that a spesific enzyme binds to and on which it acts
A substance formed as a result of a chemical reaction(Catalyst)
Digestive Tract; Mouth to anus
A physical process in which large pieces of food are torn and ground into smaller pieces
Occurs when enzymes and other chemicals break down large food molecules into smaller ones.
Involuntary waves of muscle contraction that keep food moving along in one direction through the digestive system.
A substance produced by the liver that breaks up fat particles
Fingerlike projections in the small intestine that increase surface area and maximize the absorption of nutrients.
Amount of energy needed to raise temperature 1 gram of water 1 degree C
Compounds that help regulate many vital body processes, including the digestion, absorption, and metabolism of other nutrients.
Body uses to form healthy bones and teeth, keep blood healthy, keep heart and other organs working properly.
A fat that is solid at room temperature and found in animal fats, lards, and dairy products. Bad
A fat that is liquid at room temperature and found in vegetable oils, nuts, and seeds. Good
Where fats, proteins and carbs are digested
I DONT KNOW
material between the cell membrane and the nucleus
two membranes surrounding the nucleus allowing materials to move both in and out.
a part of the cell containing DNA and RNA and responsible for growth and reproduction; the "command center" of the cell.
The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus
small particle in the cell on which proteins are assembled; made of RNA and protein. Free floating or attached to the rough ER.
Rough Endoplasmic Reticulum
Part of the cell's internal membrane system studded with ribosomes; helps to transport and export materials through and from the cell.
Smooth Endoplasmic Reticulum
Part of the cell's internal membrane system which helps to transport and export materials throughout the cell and assemble lipid-based components of the cell membrane.
Organelle associated with the ER; modifyies, sorts, and packages proteins and other materials for storage or secretion.
Enzyme-filled organelles serving as "clean-up crews" digesting organic molecules for the cell's use.
Saclike storage structures in the cell.
The site of cellular respiration; the "power house" of the cell!
The site of photosynthesis; energy from sunlight is converted into chemical energy.
Hair-like projections on the cell surface used for locamotion or the movement of fluid over a cell.
Most often a single hair-like that allows a cell to move.
The semi-permeable phospholipid bilayer surrounding a cell.
The structure outside of the cell membrane that is used to provide support and protection. Present in plants, alagae, fungi, and many prokaryotes.
Cells that contain a nucleus and are more complex/larger
ex. plants, animals, fungi
No nucleus and no membrane organelles
A tiny cell structure that carries out a specific function within the cell.
A difference in the concentration of a substance across a distance
Cavity in the cytoplasm of some protists that collects water and discharges it from the cell
Bursting of a cell
Movement of molecules from an area of higher concentration to an area of lower concentration.
A state of balance among the components of a system.
(of a solution) having a higher osmotic pressure than a comparison solution
(of a solution) having a lower osmotic pressure than a comparison solution
(used of solutions) having the same or equal osmotic pressure
Diffusion of water through a selectively permeable membrane
Movement of particles across a membrane using NO energy
Collapse of a walled cell's cytoplasm due to a lack of water. (The plant cell shrinks away from its cell wall)
The pressure that water molecules exert against the cell wall
Movement of particles across a membrane using energy
Cellular uptake of biological molecules and particulate matter via formation of new vesicles from the plasma membrane.
Process by which a cell releases large amounts of material.
A type of endocytosis in which the cell ingests extracellular fluid and its dissolved solutes.
A membrane bound sac that contains materials involved in transport of the cell.
The major air passages of the lungs that diverge from the windpipe.
Any of the many branches into which a bronchus divides.
It plays a major role in breathing, as its contraction increases the volume of the thorax and so inflates the lungs.
any of the many tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place. (oxygen diffuses into blood --> goes to heart)
Explain how oxygen gas and carbon dioxide are exchanged in the alveoli.
The change in partial pressure from the alveoli (high concentration) to the capillaries (low concentration) drives the oxygen into the tissue and the carbon dioxide into the blood (high concentration) from the tissues (low concentration), which is then returned to the lungs and exhaled. Osmosis!!!
A protein produced by some white blood cells to attack specific foreign materials.
(medicine) the condition in which an organism can resist disease
A protein that, when introduced in the blood, triggers the production of an antibody. (Foreign materials)
Red Blood cells
Blood cells that carry oxygen from the lungs to the heart.
An iron-containing protein in red blood cells that reversibly binds oxygen. (holds the oxygen in the red blood cell)
White Blood cells
Blood cells that check a foreign substance perform the function of destroying disease-causing microorganisms.
Small parts of the blood that cause clotting in order stop bleeding.
Blood is dark blue when deoxygenated. The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs.
Bright red when oxygenated. The heart pumps oxygenated blood to the body and oxygenated blood to the whole body.
The pressure of the blood in the circulatory system,
The muscular-walled tubes forming part of the circulation system by which oxygenated blood is conveyed from the heart to all parts of the body.
The tubes forming part of the blood circulation system of the body, carrying in most cases deoxygenated blood to the heart.
any of the fine branching blood vessels that form a network between the arterioles and venules. (Very small)
