The question asks about the primary mechanism by which plants release excess water. We need to identify the biological process responsible for this function.
Correct Option: C) Transpiration is the process by which plants release excess water in the form of water vapor from their aerial parts, mainly through stomata.
Newton's first law of motion, also known as the law of inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This law is fundamental to classical mechanics and defines the concept of an inertial frame of reference.
Correct Option: B) Non-inertial frame
Newton's first law of motion is not valid in a non-inertial frame of reference. In such a frame, an object can appear to accelerate even when no external force is acting on it, violating the premise of the first law. For example, if you are in an accelerating car, a loose object on the dashboard might slide backward, appearing to accelerate without any direct force pushing it. This apparent acceleration is due to the non-inertial nature of the car's frame of reference.
The question asks about India's share of new bank accounts opened globally between 2014 and 2017, according to the World Bank. This is a factual question requiring knowledge of specific statistics from the World Bank's Global Findex database.
D) 55% — The World Bank's 2017 Global Findex database report highlighted that India was responsible for 55% of all new bank accounts opened globally between 2014 and 2017. This demonstrates India's significant progress in financial inclusion during that period.
To solve this problem, we need to determine the combined filling rate of both pipes. We'll calculate the fraction of the tank each pipe fills in one hour and then add these fractions to find their combined rate. Finally, we'll take the reciprocal of the combined rate to find the total time taken to fill the tank.
Pipe A fills the tank in 45 hours. So, in 1 hour, pipe A fills:
\[ \text{Rate of A} = \frac{1}{45} \text{ of the tank} \]Pipe B fills the tank in 36 hours. So, in 1 hour, pipe B fills:
\[ \text{Rate of B} = \frac{1}{36} \text{ of the tank} \]When both pipes are opened simultaneously, their rates add up. In 1 hour, both pipes together fill:
\[ \text{Combined Rate} = \text{Rate of A} + \text{Rate of B} \]\[ \text{Combined Rate} = \frac{1}{45} + \frac{1}{36} \]The least common multiple (LCM) of 45 and 36 is 180.
If the pipes fill \(\frac{1}{20}\) of the tank in 1 hour, then they will fill the entire tank in the reciprocal of this rate.
\[ \text{Time taken} = \frac{1}{\text{Combined Rate}} \]\[ \text{Time taken} = \frac{1}{\frac{1}{20}} \]\[ \text{Time taken} = 20 \text{ hours} \]A) 20 hours — This is the correct time calculated by finding the combined filling rate of both pipes.
The question asks about the frequency of the Asian Games. To answer this, one needs to recall the established periodicity of major multi-sport events like the Asian Games.
Correct Option: C) The Asian Games are held every four years, making option C the correct answer.
Select the option figure that will complete the series of Question figure.
Option figures
The task is to identify the pattern in the sequence of figures and select the option that logically completes the series.
Correct Option: B) The pattern transformation is consistent with the sequence.
To find the father's age when the daughter was born, we need to first determine the current ages of the daughter, mother, and father. Then, we subtract the daughter's current age from the father's current age to find his age at her birth.
The problem states that the daughter is 10 years old now.
\[ \text{Daughter's current age} = 10 \text{ years} \]The mother's age now is 3 times the age of the daughter.
\[ \text{Mother's current age} = 3 \times \text{Daughter's current age} \] \[ \text{Mother's current age} = 3 \times 10 = 30 \text{ years} \]The father is 7 years older than the mother.
\[ \text{Father's current age} = \text{Mother's current age} + 7 \] \[ \text{Father's current age} = 30 + 7 = 37 \text{ years} \]When the daughter was born, her age was 0. So, we subtract the daughter's current age from the father's current age.
\[ \text{Father's age when daughter was born} = \text{Father's current age} - \text{Daughter's current age} \] \[ \text{Father's age when daughter was born} = 37 - 10 = 27 \text{ years} \]Correct Option: A) 27 years
The question asks to identify the Indian state that has approved a one percent reservation for orphans in government jobs. This is a factual question related to recent government policies in India.
D) Maharashtra — The Maharashtra government approved a one percent reservation for orphans in government jobs across all categories (General, SC, ST, OBC, etc.) in November 2018. This was a significant step towards ensuring social inclusion and providing opportunities for orphaned children.
This problem involves calculating the future value of a quantity that increases at a constant percentage rate over a period. This is a compound growth problem, similar to compound interest. We will calculate the RBC count day by day or use the compound growth formula.
Present RBC count \(P = 54000\).
Rate of increase \(r = 5\%\) per day \( = \frac{5}{100} = 0.05\).
Number of days \(n = 2\).
Increase on day 1 \( = P \times r = 54000 \times 0.05 = 2700\).
RBC count after day 1 \( = P + (P \times r) = 54000 + 2700 = 56700\).
The increase on the second day is based on the RBC count at the end of day 1.
Increase on day 2 \( = 56700 \times 0.05 = 2835\).
RBC count after day 2 \( = 56700 + 2835 = 59535\).
The formula for compound growth is \(A = P(1 + r)^n\), where:
Substitute the values:
\[ A = 54000 \left(1 + \frac{5}{100}\right)^2 \]\[ A = 54000 (1 + 0.05)^2 \]\[ A = 54000 (1.05)^2 \]\[ A = 54000 \times 1.1025 \]\[ A = 59535 \]A) The RBC count after two days would be 59535.
To identify the functional group in propanone, we need to recall the structure and general formula of propanone and then match its characteristic functional group with the given options.
Correct Option: A) Propanone contains a carbonyl group (\(C=O\)) bonded to two alkyl groups (two methyl groups in this case), which is the defining characteristic of a ketone functional group.
