Cells and Life
This "powerhouse" of the cell is responsible for converting nutrients into energy(ATP)
Mitochondria
This system is responsible for breaking down food into nutrients the body can use
Digestive System
This type of reproduction requires only one parent and results in offspring that are genetically identical
Asexual Reproduction
In a food web, these organisms get their energy by breaking down dead plants and animals.
Decomposers
These are the three subatomic particles that make up an atom.
Protons, Neutrons, and Electrons
Unlike animal cells, plant cells have this rigid outer layer and this organelle used for photosynthesis.

Cell Wall and Chloroplast
The heart, blood, and blood vessels make up this "transportation" system.
Circulatory (or Cardiovascular) System
In a Punnett Square, a capital letter represents this type of trait that can mask a recessive one.
Dominant trait
This diagram shows the many overlapping food chains in an entire ecosystem.
Food Web
This dense, central part of the atom contains both protons and neutrons.
Nucleus
This is the correct order of organization in multicellular organisms, from smallest to largest.
Cells Tissues Organs Organ Systems Organism
This system uses hormones to regulate growth, metabolism, and reproduction.
the Endocrine System
This molecule, shaped like a double helix, contains the genetic instructions for an organism.
DNA
In an energy pyramid, only about this percentage of energy is passed from one level to the next
10%
This subatomic particle has a negative charge and "swarms" around the outside of the nucleus.
Electron
This jelly-like substance fills the cell and surrounds the organelles.
Cytoplasm
When you touch something hot, your nervous system works with this system to pull your hand away.
Muscular System
If a plant has one dominant allele (T) and one recessive allele (t), its genotype is described as this
Heterozygous
These organisms are at the very bottom of the energy pyramid and produce their own food using sunlight.
Autotrophs
An atom's identity is determined by its Atomic Number, which tells you exactly how many of these particles it has.
Protons
This semi-permeable structure controls what enters and leaves the cell to maintain homeostasis
Cell Membrane
These two systems work together to ensure oxygen is taken in and delivered to every cell in the body.
Respiratory and Circulatory Systems
This is the primary advantage of sexual reproduction over asexual reproduction.
Genetic Diversity (or Variation)
This is the specific process where carbon moves from the atmosphere into living organic structures (plants)
Photosynthesis
When two or more of the same atoms are chemically bonded together, they form this, which is the smallest unit of a chemical compound.
