1. Total Residual Profit = $24,000 / 0.6 = $40,000.
2. Total Interest on Capital = ($200k + $150k) $\times$ 8% = $28,000.
3. Total Salaries = $22k + $17k = $39,000.
4. Total Interest on Drawings = ($30k + $20k) $\times$ 5% = $2,500.
Profit = Residual ($40,000) + Interest on Cap ($28,000) + Salaries ($39,000) - Interest on Drawings ($2,500) = $104,500.

Dairy Food Science and Technology QUESTION #5925

Question 9268

In standardization of milk using the Pearson Square method to produce $3.5\%$ fat milk from full-fat milk ($6\%$ fat) and skim milk ($0.1\%$ fat), the proportion of full-fat milk required is:

$\dfrac{3.4}{5.9}$ parts full-fat milk per total✔️
$\dfrac{3.5}{6.0}$ parts full-fat milk per total
$\dfrac{0.1}{5.9}$ parts full-fat milk per total
$\dfrac{2.5}{5.9}$ parts full-fat milk per total

Correct Answer Logic:

Pearson Square: desired fat $= 3.5\%$. Parts full-fat $= 3.5 - 0.1 = 3.4$. Parts skim $= 6.0 - 3.5 = 2.5$. Total $= 3.4 + 2.5 = 5.9$. Proportion of full-fat milk $= \dfrac{3.4}{5.9}$.

MBBS QUESTION #10236

Question 9269

Rigor mortis, the stiffening of muscles after death, is best explained physiologically by:

Continued ATP-dependent cross-bridge cycling after death
Depletion of cellular ATP, which is required to detach myosin heads from actin, leaving cross-bridges locked in place✔️
Excessive calcium reuptake into an intact sarcoplasmic reticulum
Loss of troponin function alone, with normal ATP levels

Correct Answer Logic:

ATP is required not for cross-bridge formation but for detaching myosin from actin, allowing the cycle to reset. After death, ATP stores are depleted and calcium leaks uncontrolled into the sarcoplasm, allowing cross-bridges to form but never releasing — producing the sustained, irreversible-until-decomposition stiffness of rigor mortis.

Agronomy QUESTION #2093

Question 9273

Osmotic adjustment in crops under drought stress is the process by which:

Plants shed their leaves to reduce total transpiring surface area
Cells actively accumulate compatible solutes (proline, glycine betaine, soluble sugars, K⁺) in the cytoplasm and vacuole, lowering osmotic potential and maintaining turgor pressure and metabolic function at lower soil water potentials — enabling continued growth and gas exchange✔️
Roots lose their selective permeability, allowing free water movement into depleted cells
Stomata permanently close to prevent any further water loss

Correct Answer Logic:

Osmotic adjustment (osmoregulation) is an active cellular response to water deficit: solutes accumulate without causing toxicity, lowering $\psi_s$ (osmotic potential) and maintaining positive turgor pressure ($\psi_p = \psi_w - \psi_s$) at lower leaf water potentials. This sustains stomatal opening, photosynthesis, root elongation into dry soil, and metabolic processes — a key drought tolerance mechanism quantified by the Pressure-Volume curve.

Question 9274

In housing design, what is the recommended minimum room height for habitable spaces?

2.1 meters
2.4 meters
2.7 meters✔️

Psychology QUESTION #9749

Question 9275

In an experiment, the group that receives no treatment is referred to as the:

Control group✔️
Experimental group
No group
Placebo group

Correct Answer Logic:

The control group is the baseline group that receives no treatment. It is compared against the experimental group to isolate the effect of the independent variable. Without a control group, results cannot be attributed solely to the treatment.

Antibodies are produced by which type of cells?

T lymphocytes
B lymphocytes (plasma cells)✔️
Macrophages

Molecular Biology / Bioinformatics / Biochemistry QUESTION #11130

Question 9278

Which reaction is the first step in photorespiration?

Decarboxylation
Oxygenation✔️
Carboxylation
Phosphorylation

Correct Answer Logic:

The first reaction of photorespiration is oxygenation — RuBisCO catalyses the addition of $\text{O}_2$ (instead of $\text{CO}_2$) to ribulose-1,5-bisphosphate (RuBP), producing one molecule of 3-phosphoglycerate and one molecule of 2-phosphoglycolate. This competitive oxygenase activity of RuBisCO initiates the photorespiratory carbon oxidation cycle. The phosphoglycolate is then dephosphorylated to glycolate, which enters the peroxisome. Photorespiration reduces photosynthetic efficiency in $\text{C}_3$ plants by up to 25–30%.

Chemistry QUESTION #4369

Question 9279

Which of the following is true about pressure for an ideal gas at $-273\ °C$?

$P = 1\ atm$
$P = 2\ atm$
$P = 3\ atm$
$P = 0\ atm$✔️

Correct Answer Logic:

$-273\ °C = 0\ K$ (absolute zero). By the ideal gas law $PV = nRT$, at $T = 0\ K$, $P = \frac{nRT}{V} = 0$. At absolute zero, all molecular motion ceases and pressure becomes zero.
