What does the cell theory state? All life is composed of cells & cells can only come from pre-existing cells. Differentiate between a unicellular organism and a multicellular organism, give an example of each. Unicellular organisms are composed of only one cell; Bacteria; Multicellular oganisms are composed of a multitude of cells, where a cell is only a part of the entire organism; People. Differentiate between unicellular and multicellular organisms in terms of cell division. (What does ...

All of the following are part of a prokaryotic cell EXCEPT... An endoplasmic recticulum Cell size is limited by... Surface to volume ratios Which structure is common to plant and animal cells? Mitochondrion In a bacterium, we will find DNA in... The nucleoid Which of the following macromolecules leaves the nucleus of a eukaryotic cell through pores in the nuclear membrane? mRNA A cell with a predominance of free ribosomes is most likely... Primarily producing proteins in the cytosol A ce...

7 characteristics of living things Order, evolutionary adaptation, regulation, reproduction, response to enviorment, growth and development, energy processing Biological organization (largest to smallest) Biosphere, ecosystem, communities, populations, organisms, organs and organ systems, tissues, cells, organelles, molecules Compare and contrast emergent properties and reductionism Emergent properties- new properties that arrive w/ each step up in hierarchy of life, complexity increases r...

Disaccharide A double sugar, consisting of two monosaccharides joined by dehydration synthesis. Glycosidic Linkage A covalent bond formed between two monosaccharides by a dehydration reaction. Phospholipid A lipid made up of glycerol joined to two fatty acids and a phosphate group. The hydrocarbon chains of the fatty acids act as nonpolar, hydrophobic tails, while the rest of the molecule acts as a polar, hydrophilic head. Phospholipids form bilayers that function as biological membranes....

Biology is the study of _______________. Life A pH of _____ is a strong base. 14 _____ are the intercellular junctions that hold cardiac muscle cells together. Gap Junctions Carbon is Atomic Number 6 so it always shares electrons True Prokayote cells and Eukaryote cells are the same size False When data supports a hypothesis, it is now proven False __________ are thought of as a junk drawer kingdom since some the organisms included don't appear to have a lot in common with each other. Pr...

Biology scientific study of organisms, living and fossil Common Features all life forms share - Made of a common set of chemical compounds - Made up of cells - Extract energy from the environment and use it to do work - Contain genetic info that enables them to develop, function, and reproduce - Use a universal genetic code to build proteins - Regulate their internal environments - Exist in populations that evolve over time Evolution Major unifying principle of biology and results in cha...

Cell Theory All living organisms are composed of one or more cells. What are the 3 important parameters in microsopy? Magnification, resoultion, and contrast. Cell structure relies on what 4 factors? Matter, energy, organization, and information What are the 2 categories all forms of life based on cell structure? Prokaryotes and Eukaryotes. The proetome of a cell determines its ? Structure and function. Prokaryotic cell Reletively simple sturctures without a nucleus, put into either bacte...

Cell division is used for which of the following ? Reproduction of single-celled organisms, growth of multicellular organisms, repair and replacement of cells, and sperm and egg production Asexual and sexual reproduction differs in that sexual reproduction_____________ Can produce great variation among the offspring (Meiosis) Asexual Reproduction ____________ Produces offspring genetically identical to the parent (Mitosis) Most of the time, DNA is in the form of____________ Euchromatin W...
