Louisiana GEE Science Assessment Practice Version with answers Note: Information items in this PowerPoint were taken from the State GEE Assessment Math Guide.State GEE Assessment Math Guide. This version of the practice assessment has answers.
DNA contains the code for making the protein (or for sequencing the amino acids). If the DNA changes, the new coding could be for a different protein (or sequence of amino acids).
Possible answers for part B include: Thorugh, RNA, the DNA code leaves the nucleus and guides the construction of the protein in the ribosomes in cytoplasm. OR RNA is used to pick up amino acids and bring them to where the protein is being made (that is, the ribosome). OR RNA makes sure the building blocks of proteins (that is, amino acids) are put in the correct order in the protein.
Because of energy loss in transfer, it takes a lot of energy (food, individual prey) to go from one level in the food chain to the next. Higher trophic levels have less energy available than lower levels do. About 90 percent of the energy is lost during the transfer from one level to the next. Only about 10 percent of the energy available is transferred from one level to the next.
Possible locations include: carbon in living organisms carbon dioxide in air carbon compounds in remains of living organisms coal diamond fossil fuels graphite limestone or carbonates (Note: Do not accept just rock.)
Long-period processes or changes: changes in the oxygen content of the atmosphere plate tectonics (uplifting and weathering of mountains) formation of coal deposits formation of sedimentary rock NOTE: Either short- or long-period processes or changes (depends on description) delta formation coastal erosion river changes course (meandering rivers)
Possible answers: [nitrogen-fixing] bacteriaconvert atmospheric nitrogen to a form used by other organisms (ammonium) [root-nodule] bacteriaconvert atmospheric nitrogen to usable products for plants consumers (animals)eat plant or animal material and produce nitrogenous wastes bacteria or fungidecompose plant and animal nitrogen compounds [nitrifying soil] bacteriaconvert ammonium to nitrites and nitrates plantsassimilate nitrates into plant material [denitrifying] bacteriaconvert nitrates to nitrogen
wildlife is affectedoil coats plants and animals and can kill them. upsets ecological balance, killing wildlife and plant life years for areas to be restored fishing and estuaries affectedfish kills, pollution negative aesthetic effect on recreational areas
4.5 cm to 5.0 cm OR The nail will be driven into the wood a distance that is about double that when it was dropped from 20 cm. Data for trials 4 and 6 show that when the distance the weight falls doubles, the distance the nail is pushed into the wood also doubles. Trial 2 shows that when a 2-kg mass falls 20 cm, the nail is pushed into the wood 2.4 cm. Therefore, when the same 2-kg mass falls 40 cm, the nail should be pushed into the wood 4.8 cm (=2.4 cm × 2).
