The weight of an object is the measure of the pull of gravity 0-100 is freezing to boiling on the celsus scale Living orginsims produce new orginsims of the same species by reproduction All living orginsims must obtain and use energy The ability to react to something in the enviroment is called irritability The metric system is based ot scaled on the powers of 10 Recorded observations are called data The ability to reproduce your results is an important part of science. The first step to the scientific method is to observe the problem Sexual reproduction is n essary because it provides for verity in the offspring The amount of matter in a substance determines its mass Scientists measure temp. in degrees Celsius The basic unit of liquid volume in metric is the liter The unit measure for length is the meter The information that you can see, hear, or smell in an experment is called data Biology is the study if all living things In outer space you can expect that your mass will stay the same.

Chemical messengers 3. Store energy The primary cellular energy source for almost all living things is the sun The 4 elements that make up most living organisms: 1. Carbon 2. Hydrogen 3. Oxygen 4. Nitrogen Mixture- A substance composed of 2 or more elements or compounds that arent chemically combined A chemical formula for a simple acid: H 20 A chemical formula for a simple base: NaOh – NA+) + Oh- 2 kinds of nucleic acids: RNA (ribonucleic acid) DNA deoxyribonucleic Pure water has an equal number of acids and base molecules.
7 ph The range of a ph scale is 0-14 Catalyst- A substance that speeds up the role of a chemical reaction Ex of Saturated Fat- Found in meat and dairy products. Ex of Non Saturated Fat- Corn oil Carbon is a unique element and the basis for fats, carbs, proteins and nucleic acid because it has a valance of 4 and combined with 4 different things Photosynthesis- Process in which autotrophs make their own food using the energy in light and CO 2 and H 2 O. General Formula for photosynthesis (balanced): CO 2 + H 20 light (CH 2 O) n+O 2 Autotrophs- Organisms that are able to use a source of energy such as sunlight to produce food from simple molecules in the environment Heterotroph’s- Organisms that obtain energy from foods they eat. When a plant releases oxygen the oxygen comes from H 2 O ATP- Cromosomes are made DNA Mitochondira- Give the cell energy Lysosomes- Break down molecules in the cell Methods that materials move threw cells: Diffusion, osmosis Active transport requires energy If red blood cells are added to water they will explode. Another name for a cell eating a particle is called phagocytosis When a cell drinks a liquid is called Dinocytosis There are 2 stages of photosynthesis A lot more energy is in glucose than there is in ATP Glucose- Sugar with formula C 6 H 12 O 6 that is a product of photosynthesis; can be broken down for energy Formula for Glucose: 6 CO 2+6 H 2 O The Citric acid cycle takes place in the inner mitochondria Oxygen is the end product of electron transport in the Mitochondrion 36 is the total number of ATP molecules produced by both glycolysis and the kerb’s cycle Fermentation- Process that enables cells to carry out energy production in the absence of oxygen 2 kinds of Fermentation: acti c acid alcon dic At 12% alcohol yeast will die Scientific Notation: . 000000456 = 4.
