extracellular matrix (ECM) correct answers a substance in which the cells of an animal tissue are embedded; consists of protein and polysaccharides biodiversity correct answers The variety of living things, encompassing genetic diversity, species diversity and ecosystem diversity intermembrane space correct answers one of the two fluid-filled internal compartments of the mitochondrion. The intermembrane space is the narrow region between the inner and outer membranes. cellulose correct answers a large polysaccharides composed of many glucose monomers linked into cable-like fibrils that provide structural support in plant cell walls. hypotonic solution correct answers in comparing two solutions, the one with the lower concentration of solutes; cells in such a solution will take up water from their surroundings. ozone layer correct answers the layer of ozone (o3) in the upper atmosphere that protects life on earth from the harmful ultraviolet rays in sunlight pH scale correct answers a measure of the relative acidity of a solution, ranging in value from 0(most acidic) to 14 (most basic). The letter pH stand for potential hydrogen ions (H) ionic bond correct answers a chemical bond resulting from the attraction between oppositely charges ions. age structure correct answers the relative number of individuals of each age in a population polar covalent bond correct answers a covalent bond between atoms that differ in electronegativity. The shared electrons are pulled closer to the more electronegative atom, making it slightly positive. chromosome correct answers a threadlike, gene-carrying structure found in the nucleus of a eukaryotic cell and most visible during mitosis and meiosis; also, the main gene-carrying structure of a prokaryotic cell. Chromosomes consist of chromatin, a combination of DNA and protein. transport vesicle correct answers a tiny membranous sac in a cell's cytoplasm carrying molecules produced by the cell. The vesicle buds from the endoplasmic reticulum or Golgi and eventually fuses with another membranous organelle of the plasma membrane, releasing it's contents. carboxyl group correct answers in an organic molecule, a functional group consisting of an oxygen atom double-bonded to a carbon atom that is also bonded to a hydroxyl group
