The breathing rate of an animal is influenced by several factors, including its metabolic rate, size, and the environment it lives in. Generally, smaller animals have higher metabolic rates and thus faster breathing rates compared to larger animals. Aquatic animals often need to process more water to extract sufficient oxygen, which can also influence their breathing rate.
Correct Option: A) Fish
This question asks about the specific Article in the Indian Constitution that mandates the preparation of the annual financial statement, commonly known as the Union Budget. To answer this, one needs to recall the relevant constitutional provisions related to financial procedures.
D) Article 112 — This Article specifically mandates the President to cause the annual financial statement (Union Budget) to be laid before both Houses of Parliament. Therefore, it is the correct answer.
The question asks why starch presence is measured in photosynthesis experiments. This relates to the end products of photosynthesis and how they are stored in plants.
D) Glucose formed is converted into starch. This is the correct reason. Glucose, the immediate product of photosynthesis, is converted into starch for storage because starch is a more stable and insoluble form, suitable for long-term energy reserves in plants. Thus, detecting starch confirms that photosynthesis has taken place.
The question asks to identify which animal population in India was severely affected by the drug Diclofenac. This requires knowledge of environmental issues and wildlife conservation in India, specifically the impact of veterinary drugs on scavenger species.
Correct Option: C) Vulture
This problem involves analyzing syllogistic statements and determining which conclusions logically follow. We will use Venn diagrams to represent the given statements and then check the validity of each conclusion based on these diagrams.
Let's combine these diagrams. We have Melons and Bananas overlapping. Bananas and Cherries are separate. Cherries are entirely within Litchis.
Correct Option: A) Only conclusion I follows
What will come in place of the question mark (?) in the following equation, if ‘+’ and ‘−’ are interchanged and also ‘×’ and ‘÷’ are interchanged?
17÷5+216×3+33−930×3+28=?
The problem requires us to evaluate an expression after interchanging certain arithmetic operations. We need to replace '+' with '-' and '-' with '+', and similarly, '×' with '÷' and '÷' with '×'. After performing these substitutions, we will evaluate the new expression following the order of operations (BODMAS/PEMDAS).
Thus, the value of the expression after interchanging the operations is 262.
Correct Option: D) 262
Refer to the following letter, symbol series and answer the question.
D & C N E ^ & G ^ Y % % @ G Y & I & * H K Z
How many consonants are there that are immediately preceded by a symbol?
To solve this problem, we need to identify all consonants in the given series that are immediately preceded by a symbol. We will go through the series element by element, checking for this specific pattern: Symbol - Consonant.
D & C N E ^ & G ^ Y % % @ G Y & I & * H K Z
The consonants immediately preceded by a symbol are: C, G, Y, G, H.
There are 5 such consonants.
A) Five — As per our step-by-step analysis, there are five consonants (C, G, Y, G, H) that are immediately preceded by a symbol.
The problem can be solved by setting up a system of two linear equations with two variables, representing the ages of A and B. We will then solve this system to find the individual ages and finally calculate their sum.
Let the age of A be \(A\) years and the age of B be \(B\) years.
From the first statement, "The sum of the age of A and twice the age of B is 42 years", we can form the first equation:
\[ A + 2B = 42 \quad \text{(Equation 1)} \]From the second statement, "When two times the age of A is added to three times the age of B, the result is 69 years", we can form the second equation:
\[ 2A + 3B = 69 \quad \text{(Equation 2)} \]Now we need to solve this system of linear equations. We can use the elimination method. Multiply Equation 1 by 2 to make the coefficient of \(A\) the same as in Equation 2:
\[ 2 \times (A + 2B) = 2 \times 42 \]\[ 2A + 4B = 84 \quad \text{(Equation 3)} \]Subtract Equation 2 from Equation 3:
\[ (2A + 4B) - (2A + 3B) = 84 - 69 \]\[ 2A + 4B - 2A - 3B = 15 \]\[ B = 15 \]Substitute the value of \(B = 15\) into Equation 1:
\[ A + 2(15) = 42 \]\[ A + 30 = 42 \]\[ A = 42 - 30 \]\[ A = 12 \]So, the age of A is 12 years and the age of B is 15 years.
The question asks for the sum of the ages of A and B:
\[ \text{Sum} = A + B = 12 + 15 = 27 \]D) 27. The sum of the ages of A and B is 27 years.
Study the given diagram carefully and answer the questions. The numbers in different sections indicate the number of persons.
In the following Venn diagram, how many girls are there who are players but not coaches?
To find the number of girls who are players but not coaches, we need to analyze the Venn diagram and identify the section that represents this specific group.
Correct Option: C) 9
To find the shortest distance between the starting and stopping points, we need to visualize the path taken by Gulshan. This involves breaking down the journey into segments based on directions and turns, and then calculating the net displacement in the East-West and North-South directions. Since all turns are 90 degrees, we can use coordinate geometry or vector addition principles.
Alternatively, we can analyze the net displacement:
Since the net North-South displacement is 0 km and the net East-West displacement is 18 km, the shortest distance from the starting point is 18 km.
B) 18 km is the shortest distance between the starting and stopping points.
