- Energy gained by stretched objects - Stored - Energy from the nucleus of atoms - Stored |
|
|
What is heat energy? |
- Occurs when energy is transferred from on place to another. - Active - Conduction, convection, radiation |
|
|
What is the conservation of energy? |
- Cannot be created or destroyed - It transforms from one for to another or one place to another - Energy transformation - Energy transfer |
|
|
What is renewable sources? What is non-renewable sources? |
- Electricity which does not run out - Electricity which will run out over time |
|
|
What is coal energy? |
- Fossil fuel formed over millions of years from decomposing plants -Burnt in power plants, heats up water and makes steam, steam pushes turbines and produces electricity. - Chemical~heat~kinetic~electrity - Non- renewable |
|
|
What is Tidal wave energy? |
- Uses the energy of tidal waves - Waves/tides turn the turbines and produce electricity. - Kinetic~kinetic~electrical - Renewable |
|
|
What is biomass energy? |
- Plant and material energy which is used to make energy - Plant and animal matter is turned into biomass fuel,biomass fuel is burnt in power stations to heat up water and turn into steam,steam pushes the turbines and produces electricity - Chemical~heat~kinetic~electricity -Renewable |
|
|
What is geothermal energy? |
- Uses heat energy from beneath the earth - Some of the heat from it goes to the surface - The steam pushes turbines in generators which produce electricity - Heat~kinetic~electrical - Renewable |
|
|
What is oil and gas energy? |
-Oil and gas are burnt in power stations to heat up water to turn into steam - The steam pushes the turbines - Chemical~heat~kinetic~electricity -Non-renewable |
|
|
What is solar electricity? |
- Heat and energy from the sun - Solar cells convert sunlight into electricity - Electrons in the solar cells move with the energy from the sunlight - Light~Electrical |
|
|
What is hydro-electricity? |
- Water from dams produce energy - Water is stored in high area using dams -Water is released down the dam - Running water pushes the turbines in generators which produce electricity -Gravitational~kinetic~kinetic~electricity -Renewable |
|
|
What is wind energy? |
- Uses the movement of the wind - Moving air turns the large wind turbines to produce electricity -Kinetic~kinetic~electrical - Renewable |
|
|
What is nuclear energy? |
- Energy made when atoms are split or joined together - Nuclear energy is released from radioactive nuclear fields - Heats up water to produce steam - Steam pushes the turbines in generators which produce electricity -Non-renewable |
|
|
What does MRS C GREN stand for? |
Movement Respiration Sensitivity Circulation Growth Reproduction Excretion Nutrition |
|
|
What is a cell? What is a unicellular organism? |
- The smallest unit of a living thing - Living things which exist as singular cells |
|
|
What is a nucleus? |
- Found at the centre of a cell - Contains DNA - Controls how the cell lives - Not found in blood cells |
|
|
What is the cell membrane? |
- Boundary of the cell - Semi-permeable - Allows certain things in and other things out - Found in both types of cells - Made of fat |
|
|
What is the mitochondria? What is a storage vacuole? |
- Where respiration is carried out - Engine room of the cell - Energy is released from the food - Food nutrients are stored for later use - Rarely found in animal cells- such as fat cells |
|
|
What is a cell wall? What is chloroplast? |
- Keeps the cell rigid and gives it shape - Made of cellulose - Only in plant cells - Photosynthesis is carried out - Only in plants - Makes plants green |
|
|
What are the organisation levels?\ What is respiration? |
-Cell~tissue~organ~system - Essential in living things to 'extract' energy from chemical resources (food) - Carried out by mitochondria -Reaction=glucose + O2 = CO2 + water + (energy) - Energy transforms ADP into ATP -Our cells get energy from ATP |
|
|
What is Aerobic respiration? What is Anaerobic respiration? |
1.- With enough oxygen gas - Glucose+O2=CO2+H2O+(Energy) - Efficient, provides large amounts of energy 2.- Without enough oxygen gas in animals - Glucose+lactic acid+(energy) - In plants : Glucose+Ethanol+CO2+Energy - Photosynthesis = CO2+H20+(Light energy)= glucose+O2 |
|
|
What is the breathing process for inhaling? What is the breathing process for exhaling? |
Outside~Nasal cavity~Trachea~Bronchus~Bronchioles~Alveoli~ Blood ~Cells Cells~Blood~Alveoli~Bronchioles~Bronchus~Trachea~Nasal Cavity~Outside |
|
|
What is in Oxygenated blood? What is in De-oxygenated blood? What is an alveoli? |
-Oxygen -Carbon Dioxide -Moist -Grape-like shape to increase surface area -Thin layer of cells -Lots of blood capillaries |
|
|
What are ciliated epithelial and goblet cells? |
-Work together to protect the alveolus -Goblet cells produce mucus to trap small particles and dirt - Ciliated epithelial cells move and beat to move the mucus out of the system |
|
|
What is the heart? What are cardiac muscles? |
- Pumps blood to our body and from our lungs - Has 4 chambers - Size of your fist -Heart is made up of cardiac muscles -Automated -Does not get tired -Needs constant supply of energy and nutrients |
|
|
What is the pathway of blood? |
Body ~ Vena cava ~ Right atrium ~ Right ventricle ~ pulmonary artery~ lungs~ pulmonary vein~ left atrium~left ventricle~aorta~blood gets oxygenated~back to the body |
|
|
What are valves and faulty valves? |
-4 valves in the heart -Ensures that blood flows in one direction -A faulty valve will reduce the efficiency of the heart -Valves can be replaced- mainly cows/pigs |
|
|
What are arteries? |
- Take blood away - Large lumen - Thick endothelium - Has thick muscular walls which push the high pressure blood along - Elastic |
