Which of the following statements is TRUE about energy in an ecosystem?
- Energy can be recycled in the same way as matter
- All energy disappears from the Earth when used, which is why we need the sun
- Every 1 pound an organism consumes creates about 10 pounds of biomass for the next organism
- About 10% of energy in living things is transferred to the next living thing when eaten
Which statement best reflects what would most likely happen if shrimp were removed from the ecosphere?
- Everything would die
- Bacteria would experience an exponential increase in population
- Bacteria and algae would both decrease, and the water would become dirty
- Algae population would increase until it reaches its carrying capacity
What statement is most true about MATTER in the ecosphere?
- It must be continuously supplied from the outside
- It is constantly being cycled within the ecosphere by the inputs and outputs of each organism
- It is cycled within the ecosphere, but organisms aren’t involved - it’s only from the environment
- It is being cycled both in and out of the ecosphere
In a study of the effects of early Alzheimer’s disease on nondeclarative memory, the Category Fluency Test to establish baseline persistence and semantic memory and language abilities. The eight subjects in the sample had Category Fluency Test scores of 11, 10, 6, 3, 11, 10, 9,11. Assume that the eight subjects constitute a simple random sample from a normally distributed population of similar subjects with early Alzheimer’s disease. (a) What is the point estimate of the population mean? (0.5) (b) What is the standard deviation of the sample? (1) (c) What is the estimated standard error of the sample mean? (0.5) (d) Construct a 90 percent confidence interval for the population mean category
- True/False: If autotrophs were destroyed, it would not have as great of an effect on the food web because heterotrophs would have more food for themselves.
heir pressures are 911.7 kPa, 3800 mmHg, and 117.6 psi.

50 ml of water sample requires 18 ml of 0.05M EDTA, during titration whereas 50 ml of
boiled water sample requires 12.5 ml of same EDTA in the titration. Calculate total,
permanent and temporary hardness of water
A ball traveling in the +x direction hits the wall at 30m/s and rebounds at 25m/s. If the ball is in contact with the wall for 4ms, determine the average acceleration of the ball during this time interval.
