name the 6 characteristics of all living things - Answer-1. acquire and use materials
and energy
2. actively maintain organized complexity

4. grow
5. reproduce
6. evolve
what are the 6 steps in the scientific method? - Answer-1. observation
2. question
3. hypothesis
4. prediction
5. experiment
6. conclusion
define science - Answer-the systematic inquiry, through observation and experiment,
into the origins and structures and behaviors of our living and nonliving surroundings
what is the difference between a question, hypothesis, and prediction? - Answer-a
question is the curiosity of a situation, a hypothesis is a proposed explanation for this
situation, and a prediction is the expected outcome of the hypothesis
what is the difference between a null hypothesis and an alternative hypothesis? -
Answer-with a null hypothesis, there is no significant difference in outcomes between
tested groups, while an alternative hypothesis expects a change
explain the difference between experimental, observational and comparative
methods of science - Answer-experimental is a test, observational is through
watching, comparative is comparing two things
what is the difference between a hypothesis and a theory? - Answer-a hypothesis is
an explanation based on assumptions where a theory is a hypothesis that can be
confirmed by others and is widely accepted
what is the difference between an atom and an element? - Answer-an atom is the
smallest unit of an element that can retain all the chemical properties of that element,
where an element is a substances that cannot be broken into simpler substances
how do atoms form molecules? - Answer-through chemical bonding (ionic, covalent,
and hydrogen bonding)
what is an ionic bond? - Answer-where electrons are transferred from one atom to
another
what is a covalent bond? what are the two types? - Answer-where electrons are
shared between atoms
, nonpolar (electrons shared equally) and polar (electrons shared equally)
what is a hydrogen bond? - Answer-attraction between two molecules that have an H
bonded to a F, O, or N
what are four unique properties of water and why do these make water essential for
life? - Answer-water is an excellent solvent, water moderates the effect of
temperature changes, water forms ice, water can be basic, acidic or neutral
describe the pH scale - Answer-
why is carbon unique? - Answer-it can either lose or gain 4 electrons, so it is
verasitile in bonding
describe the process of dehydration synthesis - Answer-
describe the process of hydrolysis - Answer-
what is the function and structure of carbohydrates? - Answer-function: provide
sugars that are then converted into ATP and used for energy
what is the function and structure of lipids? - Answer-used to store energy; insoluble
tails and soluble heads
what is the function and structure of proteins? - Answer-storage, movement,
defense, structure, signaling, catalyzing
what is the function and structure of nucleotides? - Answer-houses genetic
information
what is the difference between DNA and RNA? - Answer-DNA
-A, T, C, G
-double stranded
RNA
-A, U, C, G
-single stranded
what are the 3 components of cell theory? - Answer-1. every organism is made up of
one or more cells
2. the smallest organisms are single cells, and cells are the functional units of
multicellular organisms
3. all cells arise from preexisting cells
what are the 4 basic characteristics of all cells? - Answer-1. plasma membrane
2. cytoplasm fills cell
3. contains DNA
4. energy is transferred from environment to cells
what are the 5 steps involved in getting new proteins to the plasma membrane?
