State the producer's risk of having batches containing 2 per cent defectives rejected, and the consumer risk of having batches containing 8 per cent defectives accepted. Using the Poisson distribution, plot the operating characteristic for up to 10 per cent defectives in a batch. If the sample contains no more than 3 defectives accept the batch if it contains more than 3 defectives reject the batch.’ ‘From incoming batches take samples of 50 and inspect. 10.Ī sampling scheme is operated from the following instructions: Plot the remainder of the results and comment upon the quality of work which they indicate. Using information from the first 20 samples, draw a control chart for fraction defective. A plant performing photosynthesis will produce _ and consume _. In photosynthesis, the oxygen atoms in H2O are A. Electrons excited in photosystem I help the chloroplast produce A. ![]() Organisms that make their own organic compounds from inorganic substances are called A. Which organism's life depends on photosynthesis? A. An enzyme is a protein that catalyzes chemical reactions.ġ. An enzyme is a lipid that catalyzes chemical reactions.ħ4. In the section "Investigating Life: Does Natural Selection Maintain Cystic Fibrosis?", what is the independent variable in the figure? A. Up to 25% of a cell's ATP is used to run sodium-potassium pumps which transport sodium outside of the cell against its concentration gradient and.Ħ3. can be recharged in an exergonic reaction to form. After ATP donates a phosphate groupto a coupled reaction, thenit becomes ADP. It occursin an organism with cell walls when placed into a hypertonic environment. Which of the following is incorrect about turgor pressure? A. water will flow into the cell by facilitated diffusion.ģ5. water will flow into the cell by active transport.Į. water will flow out of the cell by osmosis.ĭ. water will flow out of the cell by active transport.Ĭ. water will flow into the cell by osmosis.ī. If a cell contains 95% water in its cytoplasm and the environment surrounding the cell contains 90% waterĪ. the environment is hypotonic to the cell.ģ4. the cell will not experience a net gain or loss of water.ĭ. the environment is hypertonic to the cell.Ĭ. the environment is isotonic to the cell.ī. If the environment surrounding a cell has a lower concentration of solute than the cellĪ. the cell will not experience a net gain or loss of water.ģ3. the cell is hypotonic to the environment.ĭ. the cell is isotonic to the environment.Ĭ. the cell is hypertonic to the environment.ī. If a cell has a greater concentration of solute than its environmentĪ. The diffusion of water across a selectively permeable membrane isģ2. cannot occur without a membrane present.ģ1. moves molecules against a concentration gradient.ĭ. utilizes proteins to move molecules across a membrane.Ĭ. occurs by blocking the production of an enzyme.Į. ![]() occurs when a substance binds to an enzyme at a site away from the active site.ĭ. occurs when a substance other than the correct substrate binds at the active site of an enzyme.ī. the concentration gradient of salt or vinegar causes osmosis out of the food and the extreme salt or pH concentration denatures the proteins, including enzymes.Ī. the concentration gradient of salt or vinegar causes osmosis out of the food.Į. equilibrium with the environment has occured.ĭ. the concentration gradient of salt or vinegar causes osmosis into the food.Ĭ. the extreme salt or pH concentration denatures the proteins, including enzymes.ī. Salted and pickled foods can last unrefridgerated for many years becauseĪ. that enzymes are most efficient at cold temperatures.Ģ7. that temperatures only affect enzymes up to a specific temperature.Į. ![]() that enzymes will not work if temperatures are too hot (or too cold).ĭ. The vertical drop slightly after the peak of each curve on the figure illustratesĪ. pH is not related to enzyme efficiency.Ģ6. optimal temperature ranges are not the same for all enzymes.ĭ. temperature is not related to enzyme efficiency.Ĭ. temperature ranges are not the same for all enzyme activity.ī. The two data curves on the figure illustrate thatĪ.
