O termo circulação refere-se ao movimento de um fluido ao longo de um circuito fechado. A circulação do sangue é o movimento do sangue originado pelo bombeamento do coração que o envia para as artérias. A função circulatória é, basicamente, uma função de transporte. Leia o texto com muita atenção e EMPREGUE o termo correto nas lacunas e faça uma legenda para inserir sua resposta: Ex: A: oxigênio
Existem duas circulações: a grande circulação e a pequena circulação
O sangue rico em A é impulsionado pelo ventrículo esquerdo saindo pela B que ramificando-se em vasos cada vez menores, leva o sangue a todas as partes do C. Em contato com as células o sangue arterial transforma-se em sangue D. Regressa ao ___E pelas veias cavas, entrando no átrio F. O sangue venoso é impulsionado pelo ventrículo ___G, saindo pela artéria H , e é conduzido até os I. Neste momento, o sangue venoso, transformado em sangue J, regressa ao coração através das veias L entrando no átrio M.

Match the descriptions / definitions with the term they best describe 1. three dimensional relationship of the different polypeptide chains in a multisubunit protein or protein complex 2. common folding pattern in proteins in which a linear sequence of amino acids folds into a right-handed coil stabilized by internal hydrogen-bonding between polypeptide backbone atoms. 3. the amino acid sequence of a protein 4. a region on the surface of a protein that can interact with another molecule through noncovalent bonding. 5. three-dimensional arrangement of alpha-helices and beta-sheets within a single polypeptide, typically stabilized by a variety of noncovalent bonds, including ionic and hydrogen bonds, and nonpolar interactions / hydrophobic force. 6. the chain of repeating carbon and nitrogen atoms, linked by peptide bonds, in a protein. 7. common structural motif in proteins in which different sections of the polypeptide chain run alongside each other and are joined together by hydrogen bonding between atoms of the polypeptide backbone. 8. portion of a polypeptide chain that has a discrete tertiary structure of its own and can often fold independently of the rest of the chain 9. regular local folding patterns in a protein, including alpha-helix and beta-sheet a. primary structure b. beta-sheet c. protein d. coiled-coil e. polypeptide backbone f. secondary structure g. side chain h. tertiary structure i. binding site j. alpha-helix k. quaternary structure l. protein domain

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
