PART B: IDENTIFY an independent variable in the experiment shown in Figure 2. JUSTIFY the 4 points use of increasing concentrations of the substrate F6P when the scientists performed the
experiments shown in Figure 2. Based on Figure 2. DESCRIBE the effect of adding AMP to the
reactions carried out at 15°C. Based on Figure 3. CALCULATE the fold increase in the
reaction rate (how many times greater the reaction rate is) between the rate at 5°C and at
25°C in the presence of 2 mM citric acid. *

Which of the following is one of the four conditions necessary for natural selection to occur in a population? fewer organisms are born than the habitat can support mutation does not occur organisms have identical characteristics variation is inherited

Acertain species of fish can have either long or short fins. the allele for long fins is dominant over the allele for short fins. a heterozygous, long-finned fish is crossed with a homozygous, short-finned fish. of the offspring, will have long fins and be , and will have short fins and be .

African penguins, which inhabit the coasts of southern africa, were classified as an endangered species in 2010. two significant threats to their survival are ecosystem damage from oil spills and overfishing by humans. overfishing depletes the food supply of african penguins. the best method to reduce the threat of overfishing would be to . the risk of oil spills could be reduced by increasing the use of , which should oil consumption. if an oil spill does occur, could be used to remove the oil so the ecosystem may more quickly recover.
