The primary structural molecule composing a cell membrane is a phospholipid.

Explanation: Cell membranes are primarily composed of a bilayer of phospholipids. Each phospholipid molecule has a hydrophilic (water-attracting) "head" and two hydrophobic (water-repelling) "tails." This arrangement allows the cell membrane to form a stable barrier between the interior of the cell and its external environment, while also providing fluidity and flexibility. The phospholipid bilayer is fundamental to the structure and function of cell membranes in all living organisms.

Decide whether the following statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain your reasoning. I bought a fund advertised on the web that says it uses a secret investment strategy to get an annual return twice that of stocks, with no risk at all. Choose the correct answer below. A. The statement does not make sense because investing in stocks is low-risk to get high returns, thus getting higher returns than stocks with this secret strategy must mean the fund advertised on the web is low-risk, not no risk. B. The statement does make sense because this secret investing strategy must be a new financial planning strategy that does not incorporate the three traditional investment considerations: liquidity, risk, and return. C. The statement does not make sense because investing in stocks is high-risk to get high returns, thus getting higher returns than stocks with this secret strategy must mean the fund advertised on the web is high-risk, not no risk. D. The statement does make sense because the strategy indicates that the return is a predictable amount, thus the fund advertised on the web is a no-risk investment.

Consider the following data for oxygen: atomic mass: 15.999 g/mol electronegativity: 3.44 electron affinity: 141. kJ/mol ionization energy: 1313.9 kJ/mol heat of fusion: 0.222 kJ/mol Does the following reaction absorb or release energy? (1) O+(g)+e− → O(g) - release - absorb - Can't be decided with the data given. Is it possible to calculate the amount of energy absorbed or released by reaction (1) using only the data above? - yes - no If you answered yes to the previous question, enter the amount of energy absorbed or released by reaction (1): 141.0 kJ / mol Does the following reaction absorb or release energy? (2) O(g) → O+(g)+e− - release - absorb - Can't be decided with the data given. Is it possible to calculate the amount of energy absorbed or released by reaction (2) using only the data above? - yes - no If you answered yes to the previous question, enter the amount of energy absorbed or released by reaction (2): 1314. kJ / mol

The average American gets a haircut every 38 days. Is the average smaller for college students? The data below shows the results of a survey of 16 college students asking them how many days elapse between haircuts. Assume that the distribution of the population is normal. 43,44,30,38,35,26,27,39, 26,24,34,33,30,26,30,38 The final conclusion is a. The data suggest the population mean is significantly lower than 38 at a=0.01, so there is sufficient evidence to conclude that the population mean number of days between haircuts for college students is lower than 38. b. The data suggest the population mean number of days between haircuts for college students is not significantly lower than 38 at a=0.01, so there is insufficient evidence to conclude that the population mean number of days between haircuts for college students is lower than 38. c. The data suggest the population mean is not significantly lower than 38 at α= 0.01 , so there is sufficient evidence to conclude that the population mean number of days between haircuts for college students is lower than 38.
