If a reaction occurs in a sealed container and a gas is produced, this happens to the total mass shown on a scale.
mass stays the same, no change in mass
This cell structure is "selectively permeable," meaning it chooses which molecules can enter or exit the system.
cell membrane
This body system is responsible for the removal of liquid waste (urea) and filtering the blood.
excretory system
This is the main genetic advantage that sexual reproduction has over asexual reproduction.
genetic variation (or diversity) in offspring, can adapt to a changing environment
These are the three necessary "inputs" (reactants) for the process of photosynthesis.
light, water, carbon dioxide
When thermal energy is added substance, the particles move in this way.
faster, further apart, less intermolecular attraction
Levels of biological organization in order from smallest to largest
cell, tissue, organ, organ system, organism
type of nerve that receives stimuli from the organisms surroundings
sensory receptors/sensory neurons
This is the main genetic advantage that asexual reproduction has over sexual reproduction.
quicker, no need to find mate, exact copy of parent (if environment is stable)
This gas is a specific chemical "waste product" of cellular respiration that plants then use for photosynthesis.
carbon dioxide
This type of reaction absorbs energy from its surroundings, often causing the temperature to drop.
endothermic
This specific organelle contains digestive enzymes to break down waste and "clean up" the cell.
When designing a prosthetic limb, the need for the limb to be "lightweight" is a criterion, while the "limited budget of $500" is this
constraint
In a Punnett Square, if one parent is homozygous dominant and the other is homozygous recessive this is the percentage of offspring that will be heterozygous.
100%

food web
When two clear liquids are mixed and a solid "precipitate" forms, this is the best evidence that this type of change occurred.
chemical reaction
The organelle that uses the code in genetic material to synthesize proteins
ribosomes
These two body systems must interact to provide oxygen to your muscles during a long-distance run.
respiratory and circulatory systems
These segments of DNA located on chromosomes code for specific proteins.
genes
A producer in this ecosystem

phytoplankton and ice algae
Using computational thinking, if the reactants side of an equation has 4 atoms of Oxygen, the products side must have this many atoms of Oxygen to be balanced.
4
the organelle that performs photosynthesis
chloroplast
This process describes how food molecules are rearranged through chemical reactions to provide the building blocks for an organism's growth.
metabolism
This is the specific three-step "pathway" or sequence that explains how a physical trait (like hair color) actually appears in an organism, starting from the instructions in the nucleus.
Gene -> Protein -> Trait
(DNA accepted)
This type of respiration produces the least amount of energy from a glucose molecule because it happens without oxygen.
anaerobic respiration/fermentation
