The question asks to identify a plant excretory product that is harmful to humans when inhaled. We need to evaluate each option based on its properties and effects on human health when inhaled.
Correct Option: C) Carbon dioxide — While plants consume carbon dioxide during photosynthesis, they also release it during respiration. In enclosed spaces or at high concentrations, inhaling carbon dioxide can be harmful to humans. It displaces oxygen, leading to suffocation, and can cause symptoms like headache, dizziness, increased heart rate, and even death at very high levels.
The question asks to identify the INCORRECT statement regarding features of a prokaryotic cell. We need to recall the defining characteristics of prokaryotic cells and compare them with the given options.
Correct Option: A) Membrane-bound cell organelles present
The question asks for the economic concept represented by the formula "Total variable cost ÷ Units of output produced". This is a direct definition question related to cost concepts in microeconomics.
Correct Option: D) Average variable cost
The formula given, "Total variable cost ÷ Units of output produced", directly defines Average Variable Cost (AVC). It represents the variable cost incurred per unit of output produced.

To determine Tamanna's walking direction, we need to understand the position of the sun and the resulting shadow direction at 6 a.m. Then, we can use the information that the tree's shadow was to her left.
A) North. Based on the sun's position at 6 a.m. (East) and the resulting shadow direction (West), if the shadow is to Tamanna's left, she must be walking North.
If L denotes ÷, M denotes ×, P denotes + and Q denotes −, then which of the following statements is true out of the options given below?
17 Q 22 M 18 P 13 L 7 = 473
13 M 64 P 24 L 18 Q 6 = 36
12 Q 13 L 15 M 19 P 23 = 96
11 L 34 M 17 P 8 Q 3 = \( \frac{42}{4} \)
This problem involves substituting given symbols with mathematical operators and then evaluating the expressions according to the order of operations (BODMAS/PEMDAS). We need to check each option to find the true statement.
Given the symbol-operator mappings:
We will evaluate each option:
Original expression: \(17 \text{ Q } 22 \text{ M } 18 \text{ P } 13 \text{ L } 7 = 473\)
Substitute operators:
\[ 17 - 22 \times 18 + 13 \div 7 \]Perform division:
\[ 17 - 22 \times 18 + \frac{13}{7} \]Perform multiplication:
\[ 17 - 396 + \frac{13}{7} \]Perform subtraction and addition:
\[ -379 + \frac{13}{7} = \frac{-2653 + 13}{7} = \frac{-2640}{7} \]Since \(\frac{-2640}{7} \neq 473\), Option A is incorrect.
Original expression: \(13 \text{ M } 64 \text{ P } 24 \text{ L } 18 \text{ Q } 6 = 36\)
Substitute operators:
\[ 13 \times 64 + 24 \div 18 - 6 \]Perform division:
\[ 13 \times 64 + \frac{24}{18} - 6 = 13 \times 64 + \frac{4}{3} - 6 \]Perform multiplication:
\[ 832 + \frac{4}{3} - 6 \]Perform addition and subtraction:
\[ 826 + \frac{4}{3} = \frac{2478 + 4}{3} = \frac{2482}{3} \]Since \(\frac{2482}{3} \neq 36\), Option B is incorrect.
Original expression: \(12 \text{ Q } 13 \text{ L } 15 \text{ M } 19 \text{ P } 23 = 96\)
Substitute operators:
\[ 12 - 13 \div 15 \times 19 + 23 \]Perform division:
\[ 12 - \frac{13}{15} \times 19 + 23 \]Perform multiplication:
\[ 12 - \frac{247}{15} + 23 \]Perform addition and subtraction:
\[ 35 - \frac{247}{15} = \frac{525 - 247}{15} = \frac{278}{15} \]Since \(\frac{278}{15} \neq 96\), Option C is incorrect.
Original expression: \[11 \text{ L } 34 \text{ M } 17 \text{ P } 8 \text{ Q } 3 = \frac{42}{4}\]
Substitute operators:
\[ 11 \div 34 \times 17 + 8 - 3 \]Perform division:
\[ \frac{11}{34} \times 17 + 8 - 3 \]Perform multiplication:
\[ \frac{11 \times 17}{34} + 8 - 3 = \frac{11}{2} + 8 - 3 \]Perform addition and subtraction:
\[ \frac{11}{2} + 5 = \frac{11 + 10}{2} = \frac{21}{2} \]The right-hand side is \(\frac{42}{4}\). We can simplify \(\frac{42}{4}\) to \(\frac{21}{2}\).
Since \[\frac{21}{2} = \frac{21}{2}\], Option D is correct.
D) After substituting the operators and following the order of operations, the left-hand side of the equation \(11 \text{ L } 34 \text{ M } 17 \text{ P } 8 \text{ Q } 3\) evaluates to \(\frac{21}{2}\), which is equal to the right-hand side \(\frac{42}{4}\).
There are 43 cadets in a battalion, and the commander is planning for a straight row arrangement of cadets on stage, facing north. P is 18th from the left side of the row and Q is 31st from the right side of the row. Find the number of cadets standing between P and Q.
This problem involves finding the number of cadets between two specific cadets, P and Q, in a row. We are given the total number of cadets, and the positions of P from the left and Q from the right. Since the sum of their positions from opposite ends exceeds the total number of cadets, it indicates an overlapping case.
First, let's find the sum of the positions of P and Q from opposite ends:
\[ \text{Sum of positions} = \text{Position of P from left} + \text{Position of Q from right} \]\[ \text{Sum of positions} = 18 + 31 = 49 \]Since the sum of their positions (49) is greater than the total number of cadets (43), it is an overlapping case. This means P and Q have crossed each other's positions.
In an overlapping scenario, the number of cadets between two individuals can be found using the formula:
\[ \text{Cadets between P and Q} = (\text{Position of P from left} + \text{Position of Q from right}) - \text{Total cadets} - 2 \]The '-2' accounts for P and Q themselves, as they are included in the sum of positions but should not be counted as being 'between' each other.
\[ \text{Cadets between P and Q} = 49 - 43 - 2 \]\[ \text{Cadets between P and Q} = 6 - 2 \]\[ \text{Cadets between P and Q} = 4 \]C) 4 is the correct answer. There are 4 cadets standing between P and Q.
