Psychology QUESTION #9754

According to Maslow, can a person lacking a job, friends, and a home still achieve self-actualization?

100% yes
100% No✔️
None of these
It depends

Correct Answer Logic:

According to Maslow's hierarchy of needs, self-actualization can only be reached after lower needs (physiological, safety, belonging, esteem) are met. A person lacking job, friends, and home has unmet basic needs, making self-actualization impossible under his model.

Physics QUESTION #7048

Question 9629

In a YDSE, slits are $0.5 \text{ mm}$ apart and the screen is $150 \text{ cm}$ away. Using wavelengths $650 \text{ nm}$ and $520 \text{ nm}$, find the minimum distance from the central maximum where bright fringes from both wavelengths overlap.

$15.6 \text{ mm}$
$1.56 \text{ mm}$
$7.8 \text{ mm}$✔️
$9.75 \text{ mm}$

Correct Answer Logic:

Overlap occurs when $n_1 \lambda_1 = n_2 \lambda_2$.

$n_1(650) = n_2(520) \implies \frac{n_1}{n_2} = \frac{520}{650} = \frac{4}{5}$.

Distance $y = \frac{n_1 \lambda_1 D}{d} = \frac{4 \times 650 \times 10^{-9} \times 1.5}{0.5 \times 10^{-3}} = 7.8 \times 10^{-3} \text{ m} = 7.8 \text{ mm}$.

Question 9631

The Milk to Acid to Amyl Alcohol ratio in the standard Gerber test is:

$10\;\text{mL}$ milk : $5\;\text{mL}\;\text{H}_2\text{SO}_4$
$11\;\text{mL}$ milk : $10\;\text{mL}\;\text{H}_2\text{SO}_4$ : $1\;\text{mL}$ amyl alcohol✔️
$10\;\text{mL}$ milk : $1\;\text{mL}$ amyl alcohol only
$1\;\text{mL}$ milk : $10\;\text{mL}\;\text{H}_2\text{SO}_4$

Correct Answer Logic:

Standard Gerber method: $10\;\text{mL}\;\text{H}_2\text{SO}_4$ ($d = 1.820\text{–}1.825\;\text{g/mL}$) $+ 11\;\text{mL}$ milk $+ 1\;\text{mL}$ amyl alcohol in a Gerber butyrometer. The acid dissolves all milk components except fat. Centrifugation separates fat into the graduated neck for direct volumetric reading ($\%$ fat).

Chemistry QUESTION #7134

Question 9637

An ideal gas undergoes an isothermal expansion from $1\text{ dm}^3$ to $10\text{ dm}^3$ at $300\text{ K}$ against a constant external pressure of $1\text{ bar}$. Determine the change in entropy of the surroundings ($\Delta S_{surr}$) in $\text{J K}^{-1}$.

$3.0$
$-3.0$✔️
$2.5$
$-2.5$

Correct Answer Logic:

In an irreversible expansion against constant external pressure, the work done by the gas is $w = -P_{ext}\Delta V = -1 \text{ bar} \times (10 - 1) \text{ dm}^3 = -900\text{ J}$. For an isothermal process of an ideal gas, $\Delta U = 0$, so $q_{sys} = -w = 900\text{ J}$. The heat gained by the surroundings is $q_{surr} = -q_{sys} = -900\text{ J}$. Thus, $\Delta S_{surr} = \frac{q_{surr}}{T} = \frac{-900}{300} = -3.0\text{ J K}^{-1}$.

Statistics QUESTION #2010

Question 9638

Laspeyres' price index uses quantities of the __________ period as weights, while Paasche's index uses quantities of the __________ period.

Current; base
Base; current✔️
Base; base
Current; current

Correct Answer Logic:

Laspeyres' index $= \dfrac{\sum p_1 q_0}{\sum p_0 q_0} \times 100$ uses base period quantities $q_0$ as fixed weights. Paasche's index $= \dfrac{\sum p_1 q_1}{\sum p_0 q_1} \times 100$ uses current period quantities $q_1$. Fisher's Ideal index is the geometric mean of both.

Molecular Biology / Bioinformatics / Biochemistry QUESTION #11127

Question 9639

Totipotency — the ability of a single cell to develop into a complete organism — has been demonstrated by:

Xylem
Meristem✔️
Cork
All of these

Correct Answer Logic:

Meristematic cells demonstrate totipotency most clearly — they are undifferentiated, actively dividing plant cells capable of differentiating into any cell type and regenerating a complete plant. F.C. Steward (1958) demonstrated plant totipotency by regenerating complete carrot plants from single phloem cells. While theoretically all plant cells retain the complete genome and are totipotent, meristematic cells most actively express this potential. Xylem cells are highly differentiated; cork cells are dead.
