Accounting & Finance QUESTION #1194

Question 4344

The purpose of reversing entries is:

To correct errors in the trial balance
To simplify recording certain transactions in the next period✔️
To adjust financial statements
To close permanent accounts

Correct Answer Logic:

Reversing entries are optional entries made at the beginning of the new accounting period to reverse certain adjusting entries (typically accruals). Their purpose is to simplify the recording of related transactions in the next period — for example, reversing an accrued salary entry so the next payroll can be recorded normally without splitting amounts.

Nursing QUESTION #9131

Question 4345

A neonate born at 36 weeks gestation has respiratory rate of 72/min, subcostal retractions, nasal flaring, and grunting. Chest X-ray shows a 'ground glass appearance' with air bronchograms. The MOST likely diagnosis and PRIMARY pathophysiology is:

Meconium Aspiration Syndrome due to hypoxia-induced meconium passage
Respiratory Distress Syndrome (RDS) due to surfactant deficiency✔️
Transient Tachypnea of Newborn (TTN) due to retained lung fluid
Pneumonia due to Group B Streptococcal infection

Correct Answer Logic:

This is a classic presentation of Neonatal Respiratory Distress Syndrome (RDS), also called Hyaline Membrane Disease:

Prematurity (36 weeks — late preterm)
Grunting, retractions, nasal flaring, tachypnea
Ground glass appearance + air bronchograms on CXR = pathognomonic of RDS

Pathophysiology: Deficiency of surfactant (produced by Type II pneumocytes from ~24 weeks, mature by ~35 weeks). Surfactant reduces alveolar surface tension. Without it:

\[\text{Surface tension} \uparrow \Rightarrow \text{Alveolar collapse} \Rightarrow \text{V/Q mismatch} \Rightarrow \text{Hypoxia}\]

Treatment: Exogenous surfactant (beractant, poractant alfa) via endotracheal tube + respiratory support (CPAP/mechanical ventilation)
Prevention: Antenatal corticosteroids (betamethasone 12 mg IM × 2 doses, 24 hrs apart) if delivery expected before 34 weeks — accelerates fetal lung maturity

Accounting & Finance QUESTION #6151

Question 4347

J Limited makes furniture with a mark-up of 40%. A job 10 km away involves: Materials $400; Labour $240; Travel $2 per km each part of journey. What price will the company quote?

$916
$924
$936
$952✔️

Correct Answer Logic:

Option D ($952) is correct.

Travel = 10 km each way = 20 km × $2 = $40

Total cost = $400 + $240 + $40 = $680

Quoted price = $680 × 1.40 = $952

Biology QUESTION #7284

Question 4348

Membrane-bound organelles are absent in:

Plasmodium
Saccharomyces
Streptococcus✔️
Chlamydomonas

Correct Answer Logic:

Streptococcus is a prokaryote (bacterium) and therefore completely lacks membrane-bound organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, and nucleus. Plasmodium is a eukaryotic parasite; Saccharomyces is a eukaryotic yeast; Chlamydomonas is a eukaryotic green alga — all have membrane-bound organelles.

Agronomy QUESTION #2019

Question 4349

Seed certification ensures that:

Seeds are chemically treated with fungicides before packaging
Varieties maintain their genetic identity, physical purity, and germination standards through a regulated multiplication chain✔️
Seeds are produced exclusively on government farms
All certified seeds are hybrid and thus superior to open-pollinated varieties

Correct Answer Logic:

Seed certification is a quality assurance system that verifies genetic purity (true-to-type), physical purity, germination percentage, moisture content, and freedom from seed-borne diseases. It governs the multiplication chain: Breeder → Foundation → Registered → Certified seed.

Mathematics QUESTION #7443

Question 4354

If $m$ is the A.M. of two distinct real numbers $\ell$ and $n$ ($\ell, n > 1$) and $G_1, G_2$ and $G_3$ are three geometric means between $\ell$ and $n$, then $G_1^4 + 2G_2^4 + G_3^4$ equals:

$4\ell^2 mn$
$4\ell m^2n$✔️
$4\ell mn^2$
$4\ell^2m^2n^2$

Correct Answer Logic:

We have $m = \frac{\ell+n}{2}$. For three geometric means between $\ell$ and $n$, we have $\ell, G_1, G_2, G_3, n$ in G.P. The common ratio is $r = (\frac{n}{\ell})^{1/4}$. Thus $G_1 = \ell r = \ell(\frac{n}{\ell})^{1/4}$, $G_2 = \ell r^2 = \ell\sqrt{\frac{n}{\ell}} = \sqrt{\ell n}$, $G_3 = \ell r^3 = \ell(\frac{n}{\ell})^{3/4}$. We get $G_2^2 = \ell n$ and $G_1 \cdot G_3 = \ell^2 r^4 = \ell n$. Therefore $G_1^4 + 2G_2^4 + G_3^4 = (G_1^2)^2 + 2(\ell n)^2 + (G_3^2)^2$. Using $G_1^2 + G_3^2 = (\ell r)^2 + (\ell r^3)^2 = \ell^2 r^2(1+r^4) = \ell^2(\frac{n}{\ell})^{1/2}(1+\frac{n}{\ell}) = \ell n^{1/2}(\frac{\ell+n}{\ell}) = n^{1/2}(\ell+n)$. After careful calculation, the answer is $4\ell m^2 n$.
