What are the essential life processes?
A monosaccharide made up of six carbon atoms, twelve hydrogen atoms and six oxygen atoms.
What is glucose?
Alternative forms of a gene that code for the different variations of a specific trait.
What are alleles?
Heterotrophs that obtain organic nutrients from dead organisms by external digestion.
What are saprotrophs?
The contraction of muscle layers in your "food tubes" that moves food along and mixes food with enzymes.
What is peristalsis?
The organelle of eukaryotic cells that is responsible for transporting, modifying, and packaging proteins and lipids.
What is the Golgi Apparatus?
An important enzyme that unwinds DNA during DNA replication
What is DNA Helicase?
This shows the chromosomes of an organism in homologous pairs of decreasing length.
What is a karyogram?
This is produced from organic matter in anaerobic conditions by methanogenic archaeans and some diffuses into the atmosphere or accumulates in the ground.
What is methane?
This sends out an electrical signal that stimulates contraction as it is propagated through the walls of the atria and then the walls of the ventricles.
What is the sinoatrial or SA Node?
The movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient requiring ATP.
What is Active Transport?
The type of macromolecule that contains more energy per gram than carbohydrates (about twice as much).
What are lipids?
The phase of meiosis where random orientation occurs.
What is metaphase I?
Cane toads, rabbits, kudzu
What are examples of invasive species?
The two scientists who completed experiments to test penicillin on bacterial infections in mice.
Who is Florey and Chain?
The idea that mitochondria and chloroplasts in today's eukaryotic cells were once separate prokaryotic microbes.
What is endosymbiotic theory?
The level of protein structure where the number and arrangement of multiple folded protein chains combines into a multi-subunit complex.
What is quaternary structure?
The appendix of humans and the pelvic bone of whales may be considered examples of these.
What are vestigial structures?
An organism used to assess a specific environmental condition.
What is an indicator species?
These are extremely thin alveolar cells that are adapted to carry out gas exchange.
What are Type I Pneumocytes?
The stage in mitosis where each pair of chromosomes is separated into two identical, independent chromosomes. The chromosomes are separated by a structure called the mitotic spindle.
What is anaphase?
4.186 J/g°C
What is the specific heat capacity of water?
Roots, leaves in fronds, and a vascular system describe which phylum of plants.
What is Filicinophytes?
This type of conservation may require active management of nature reserves or national parks.
What is in situ conservation?
This substance can block the synaptic transmission at cholinergic synapses in insects by binding to acetylcholine receptors.
What is neonicotinoid pesticides?
