Science 8: Biology MEGA QUIZ

A multicellular unicellular( multicellular, unicellular ) organism is better because the jobs of the cells are more spread out confined( spread out, confined ). In a unicellular organism, that one cell has to take care of the entire organism entire organ brain( entire organism, entire organ, brain ). Unicellular organisms interact directly through blood through oxygen( directly, through blood, through oxygen ) with the outside world. Multicellular organisms use blood cell membrane oxygen( blood, cell membrane, oxygen ) to transport nutrients to their organs organelles( organs, organelles ).

Every cell in a multicellular unicellular( multicellular, unicellular ) organism is specialized to do its function. Nerve cells are long and spread out small and tight compressed thin and flowy( long and spread out, small and tight, compressed, thin and flowy ) because they need to take signals multiply( take signals, multiply ) from many places to the brain. Red blood cells are disklike flat round( disklike, flat, round ) so they can flow slide push through things( flow, slide, push through things ) and transport oxygen.

Organelles Machines Organs DNA RNA Orgenallas( Organelles, Machines, Organs, DNA, RNA, Orgenallas ) are the structures within outside of around on the roof of( within, outside of, around, on the roof of ) cells that carry out activities necessary for life. The most common cell organelles between both an animal and plants cell include: Nucleus Chloroplasts( Nucleus, Chloroplasts ), Vacuole Diaphragm Alveoli( Vacuole, Diaphragm, Alveoli ), Membrane Cell Wall( Membrane, Cell Wall ), and Cytoplasm Semipermeable Citoplasm Floor( Cytoplasm, Semipermeable, Citoplasm, Floor ).

Xylem transports water and solutes glucose and amino acids( water and solutes, glucose and amino acids ) from the roots to leaves roots to anywhere it's needed( the roots to leaves, roots to anywhere it's needed ).
Phloem transports glucose and amino acids water and solutes( glucose and amino acids, water and solutes ) to where it's needed roots to leaves( where it's needed, roots to leaves ).

Xylem is made of dead living( dead, living ) cells that are impermeable permeable semi-permeable( impermeable, permeable, semi-permeable ) to water.
Phloem is made of living dead( living, dead ) cells that move things.

Xylem tissue: If placed in the middle, it can protect it from being pulled from the ground being squashed or bent( being pulled from the ground, being squashed or bent ). If placed near the edge, the plant can't be squashed or bent pulled from the ground( squashed or bent, pulled from the ground ).

Transpiration is the evaporation condensation leaking( evaporation, condensation, leaking ) of water from stem and leaves roots flowers( stem and leaves, roots, flowers ). This helps move water up down( up, down ) the plant. It creates a transpiration pool transpiration pond evaporation pool evaporation pond( transpiration pool, transpiration pond, evaporation pool, evaporation pond ) that draws water up the plant. Water is cohesive a liquid transparent( cohesive, a liquid, transparent ) which helps this.

Roots have root hairs root fingers nerves( root hairs, root fingers, nerves ), giving them a large surface area volume capacity( surface area, volume, capacity ) for water absorption suction evaporation( absorption, suction, evaporation ). Water enters through osmosis diffusion( osmosis, diffusion ) to the concentration gradient and finally to xylem vessels.

Diffusion Osmosis( Diffusion, Osmosis ): The spreading of something (particles) from an area of high concentration low concentration( high concentration, low concentration ) to an area of low concentration high concentration( low concentration, high concentration ); to spread out evenly unevenly on one side( evenly, unevenly, on one side )

Osmosis Diffusion( Osmosis, Diffusion ): Molecules of a solvent passing through a semi-permeable permeable impermeable( semi-permeable, permeable, impermeable ) membrane from a highly concentrated lower concentrated( highly concentrated, lower concentrated ) solution to a lower concentrated higher concentrated( lower concentrated, higher concentrated ) solution; evening out unevening( evening out, unevening ) the concentration of either side.

Functions of the organs in the digestive system:

Mouth: Chews up and sends food down the esophagus trachea throat( esophagus, trachea, throat )
Esophagus: Transports food to the stomach/liver stomach/lung liver/lung pancreas/stomach( stomach/liver, stomach/lung, liver/lung, pancreas/stomach )
Stomach: Uses three four two( three, four, two ) layers of muscle to physically mix squeeze absorb( mix, squeeze, absorb ) food(only begins digesting meat vegetables wheat( meat, vegetables, wheat )). Makes and secretes stomach acids juices( acids, juices ) and Pepsin insulin blood( Pepsin, insulin, blood ).
Liver: Filters blood food water( blood, food, water ) coming from the digestive tract before passing it to the rest of the body stomach heart( rest of the body, stomach, heart ). Secretes bile acids( bile, acids ) to intestines
Gallbladder: Secretes bile acids( bile, acids ) and helps digest fatty meaty chewy( fatty, meaty, chewy ) foods
Pancreas: Produces enzymes that help break down separate warm up( break down, separate, warm up ) food. Also makes insulin bile Pepsin acids( insulin, bile, Pepsin, acids ) that tells the liver and pancreas stomach kidneys( pancreas, stomach, kidneys ) how much glucose to take in
Small Intestine: Where 90% 85% 80% 95%( 90%, 85%, 80%, 95% ) of food absorption of minerals vitamins( minerals, vitamins ) from food takes place
Large Intestine: Absorbs water liquids minerals( water, liquids, minerals ) and produces waste

In the small intestine...

Proteins > Amino acids Sugars Lipids Muscles( Amino acids, Sugars, Lipids, Muscles )
Carbohydrates > Sugars Amino acids Fats Lipis( Sugars, Amino acids, Fats, Lipis )
Fats > Lipids Sugars Amino acids( Lipids, Sugars, Amino acids )

Functions of the organs in the circulatory system:

Heart: Pumps and cleans Filters Removes and creates( Pumps and cleans, Filters, Removes and creates ) blood throughout the body while supplying nutrients and oxygen carbon dioxide( oxygen, carbon dioxide ) and removing creating( removing, creating ) waste
Arteries: Carries clean used( clean, used ) blood from the heart organs( heart, organs ) and to other organs the heart( other organs, the heart )
Veins: Carries used cleaned( used, cleaned ) blood from the organs heart( organs, heart ) back to the heart organs( heart, organs ) to be cleaned used( cleaned, used )
Capillaries: Transfers oxygen and nutrients from the bloodstream heart liver( bloodstream, heart, liver ) to the organs heart bloodstream( organs, heart, bloodstream ) directly. Only one two three four( one, two, three, four ) cell cells milimeters milimeter( cell, cells, milimeters, milimeter ) wide.
Blood: Carries things between organs

Functions of the organs in the nervous system:

Brain: Receives and sends signals particles feelings( signals, particles, feelings ) to respond changes to our surroundings

Functions of the organs in the respiratory system:

Mouth/Nasal Cavity: Takes in oxygen carbon dioxide( oxygen, carbon dioxide ) and gets rid of carbon dioxide oxygen( carbon dioxide, oxygen ) through the trachea esophagus arteries( trachea, esophagus, arteries ). Nasal cavity detects smell taste sight( smell, taste, sight ).
Trachea: Transports air between the mouth and lungs mouth and nose lungs and heart( mouth and lungs, mouth and nose, lungs and heart ). Splits off at the back off the throat.
Larynx: Also known as the voice box talk box pharynx( voice box, talk box, pharynx ). Air passes through this to make our voice.
Lungs: Takes oxygen carbon dioxide( oxygen, carbon dioxide ) from the trachea esophagus larynx( trachea, esophagus, larynx ), gives it to the blood organs tissues( blood, organs, tissues ) and takes carbon dioxide oxygen waste( carbon dioxide, oxygen, waste ) out. Protected by the ribs heart spine( ribs, heart, spine ). Left Right( Left, Right ) lung protects the heart.
Bronchia: A split organ pipe( split, organ, pipe ) in the trachea to distribute air between the lungs.

Alveoli: Tiny air bubbles that hold oxygen carbon dioxide( oxygen, carbon dioxide ) in the lungs. They tend to pop grow multiply( pop, grow, multiply ) regularly. Humans start off with 600 million 800 million 300 million 500 million( 600 million, 800 million, 300 million, 500 million ). Oxygen is taken to blood by capillaries veins arteries( capillaries, veins, arteries ).

Functions of the organs in the excretory system:
