Biology: The Essentials

When trees are removed from an area, patches or strips of untouched trees often intersperse the deforested land. How is the abiotic environment on the edge of these strips or patches different from before the area was disturbed? What changes in vegetation would you expect to see in the next few years? How might animals be affected by forest fragmentation?

Nanoparticles are tiny bits of metal that are used in sunscreens, as a wastewater treatment, and for many other purposes. Recent evidence suggests that nanoparticles are toxic to phytoplankton, the primary producers at the base of many aquatic food chains. Phytoplankton use the energy in sunlight to produce organic matter, and they consume $\mathrm{CO}_{2}$ and release $\mathrm{O}_{2} .$ Predict some possible consequences to biodiversity if nanoparticles become a more common pollutant.

Algebra

You and your friend are debating. Your friend says: "A valid line of reasoning does not contain fallacies. A correct conclusion follows from a valid argument together with true premises. There is a fallacy in your argument. Therefore, your conclusion is not correct." Use F for "reasoning has fallacy", V for "argument is valid", P for "premises are true" and C for "conclusion is correct". Your friend's premises are (formulas): Your friend's conclusion is (formula): Your friend's argument is: valid/invalid. If invalid, provide a counterexample.

a) Fixed expenses are expenses that do not change from month to month, and variable expenses are expenses that can fluctuate from month to month. Complete the second column of the chart by determining if each expense is fixed or variable.
b) Choose an example of a fixed expense and an example of a variable expense, and explain why they are classified that way.
Step 2: Calculating Monthly Expenses
The second step to building a family budget is to outline your expenses in greater detail; itemizing fixed and variable expenses. Suppose the table below shows your family's monthly expenses by category.
a) Fixed expenses are expenses that do not change from month to month, and variable expenses are expenses that can fluctuate from month to month. Complete the second column of the chart by determining if each expense is fixed or variable. (10 points, 2 points each)
b) Choose an example of a fixed expense, and an example of a variable expense, and explain why they are classified that way. (4 points)
