Hypothesis - Tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation Variable - To vary or change Independent Variable - A manipulated variable in an experiment or study whose presence or degree determines the change in the dependent variable (thecause) Dependent Variable - The observed variable in an experiment or study whose changes are determined by the presence or degree of one or more independent variables (the effect) C...

Flowers - The reproductive structure in plants Double Fertilization - One sperm unites with an egg, forming a diploid zygote, and the other unites with polar nuclei, forming a triploid endosperm nucleus. Eudicotyledones (Eudicots) - -Two cotyledons -Flowering parts in four of fives or multiples of four or five -Pollen grain with three pores -woody or herbaceous -usually net venation -vascular bundles in a ring -taproot system Alteration of generations - The alteration of two or more di...

Marine Bio CH. 1, 5, & 6 Quiz 100% Pass What is marine biology? The study of organisms that live in the sea. Marine bio facts not a separate science an applied field of biology and incorporates others: geology, chemistry Marine biologists study organisms that inhabit the sea (living things) Oceanographers study physical aspects (tides, currents) Why study marine bio? since life is believed to have risen in the sea, studying MB could provide a clue about links to our evolution many products c...

beta-oxidation correct answer: enzymes repeatedly split off pairs of they hydrogenated carbon atoms that make up a fatty acid and join each pair to coenzyme A to form acetyl-CoA Chloroplasts correct answer: light harvesting structures found in photosynthetic eukaryotes; synthesize a few polypeptides compare and contrast archaeal flagella with bacterial flagella correct answer: archaeal are about half as thick as bacteria; not hollow; lack a central channel; flow together; powered by ATP...

Structure of Nucleus. 1. Nuclear envelope: double membrane surrounding nucleus, outer membrane continuous with the (R)ER of the cell. 2. Nuclear pores: allow the passage of larger molecules, such as mRNA, out of the nucleus. 3. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus. 4. Chromosomes: protein-bound, linear DNA. 5. Nucleolus: small spherical region(s) in nucleoplasm. Manufactures ribosomal RNA and assembles ribosomes. Function of Nucleus. 1. Controls...
