what is enzyme - CORRECT ANSWER-biological catalyst
what is substrate - CORRECT ANSWER-The substance which the enzyme acts
upon
what is active site - CORRECT ANSWER-where the reaction occurs
,describe the structure and funcion of nucleic acids - CORRECT ANSWER-made
of 5c sugar, phosphate group, nitrogenous group (helix). The function is to contain
genetic material snd conduct protein synthesis
what are the similarities and differences between DNA and RNA - CORRECT
ANSWER-similarities- both contain a form of ribosomes, and both are nucleic
acids
differences- DNA has thymines and RNA has uracil; DNA contains deoxyribose and
RNA uses ribose for sugar.
List and describe the parts of the cell theory - CORRECT ANSWER-All living
things are made cells which is the basic units of structure and the function. It also
states that all cells come from other preexisting cells.
List and describe the steps of the scientific method - CORRECT ANSWER-1.
Make an observation: noticing something and asking a question about what was
observed. 2. Formulate a hypothesis: making an educated guess/prediction of
what is happening and why. 3. design experiment. 4. Collect data. 5. develop a
theory. 6. publish
list and describe the chartacteristics of life - CORRECT ANSWER-1. All living
things are made up of 1 or more cells. 2. Hierarchical organization (organelles -
biosphere) 3. reproduce --> a-sexual reproduction does not need a partner (has
, no diversity) 4. sexual reproduction increases diversity. 5. grow and develop. 6.
respond to their environment
What is a chemotroph? - CORRECT ANSWER-use chemical energy
what is phototrophs - CORRECT ANSWER-use the sun for energy
what is autotroph - CORRECT ANSWER-inorganic material
What is a heterotroph? - CORRECT ANSWER-organic material
what is homeostasis - CORRECT ANSWER-internal response
what is irritability - CORRECT ANSWER-external response
Desribe the structure of an atom - CORRECT ANSWER-1. nucleus (center
contains protons+ and neutrons.) 2. energy levels (electrons(-) orbits nuclues. 3.
atomic number (the number of protons). 4. atomic mass (number of protons and
neutrons. electrons too small to count. 6. mass number = neutrons. 7. number of
protons = number of electrons.
