Briefly explain these symbiotic relationships: parasitism, mutualism, commensalism.
A stable resting state in an organism
Mitosis and/or cell cycle
Many possible answers
They do not have organelles and require a host cell for reproduction
G1: growth; S: DNA synthesis; G2: growth; Mitosis: split nucleus; Cytokinesis: split cytoplasm
DNA--transcription-->mRNA--translation-->protein
To reduce chromosome number for fertilization
100%; 50%
Protein: amino acid/polypeptide; Lipid: Fatty acid or tryglyceride/fat; Carbs: monosaccharide/polysaccharide; Nucleic Acids: nucleotide/nucleic acid
Different sugar, T in DNA, U in RNA, and DNA is double stranded
Fossils
Archaebacteria and Eubacteria
Categorizing organism; in order to have a universal system of nomenclature
Homologous structures, similar DNA sequences, similar embryology, biogeography, fossils
Overproduction, Variation, Competition, Survival of the fittest
glucose (C6H12O6) + oxygen (O2) --> carbon dioxide (CO2) + water (H2O) + ATP
carbon dioxide (CO2) + water (H2O) --> glucose (C6H12O6) + oxygen (O2)
They lower the energy of activation, speeding up reactions
Ground: support and photosynthesis; Vascular: transport; Dermal: protection
Many answers; the stimulus is reversed
Organisms of the same species in the same place for populations; groups of populations are communitites
Thick cuticle, reduced leaves, extensive roots, water storage systems
0.1%
Water cycle, Carbon cycle, Nitrogen cycle
Parasitism: +/- Mutualism: +/+ Commensalism: +/0
