Cell Biology
This organelle is the site of anaerobic respiration in eukaryotic cells.
Cytoplasm
This monomer is the building block of carbohydrates.
Polysaccharides
This term describes an organism with two identical alleles for a gene.
Homozygous
This term describes all organisms of one species in a habitat.
Population
This vessel carries oxygenated blood away from the heart.
Artery (or Aorta)
This process describes the movement of water across a semi-permeable membrane.
Osmosis
This enzyme unwinds the DNA double helix during replication.
Helicase
This technique separates DNA fragments by size using an electric field.
Gel electrophoresis
This process converts atmospheric nitrogen into ammonia by bacteria.
Nitrogen fixation
This hormone lowers blood glucose concentration after a meal.
Insulin
This phase of the cell cycle involves DNA replication.
Interphase (or S phase)
This process converts mRNA codons into a polypeptide chain.
Translation
This chromosomal abnormality causes Down syndrome in humans.
Trisomy 21
This pyramid shape is always upright in terrestrial ecosystems.
Energy pyramid
This part of the neuron receives signals from other cells.
Dendrite
This process allows large particles to enter a cell by engulfing them.
Endocytosis (or Phagocytosis)
This factor describes how temperature or pH changes reduce enzyme activity permanently.
Denaturation
This type of inheritance results in a blend of parental phenotypes.
Incomplete dominance
This gas is the primary driver of the enhanced greenhouse effect.
Carbon dioxide (CO2)
This muscle contracts to increase the volume of the thorax during inhalation
Diaphragm
This phenomenon explains why cells cannot grow indefinitely large.
Surface area to volume ratio
This characteristic of DNA is demonstrated by the two strands running opposite directions.
Antiparallel
This type of inheritance allows male carriers.
Autosomal recessive
This term describes a non-native species that harms local ecosystems.
Invasive species (or Alien species)
This type of white blood cell produces antibodies to fight pathogens.
B-lymphocyte (or B-cell / Plasma cell)
