This question tests knowledge of plant tissues and their specific functions related to transport. We need to identify the tissues responsible for water and mineral transport, and for food transport (products of photosynthesis).
Therefore, the correct words to fill the blanks are 'xylem' and 'phloem' respectively.
Correct Option: D) xylem, phloem
To classify a carbon compound as an alcohol, we need to identify the presence of the characteristic functional group for alcohols. Alcohols are organic compounds containing a hydroxyl group (-\(\text{OH}\)) attached to a saturated carbon atom. We will examine the functional groups associated with each given option.
Correct Option: B) Propanol
The problem asks us to identify numbers in a given series that are immediately preceded by another number and immediately followed by a symbol. We need to scan the series from left to right and apply this condition to each number.
D) One β The number '8' is immediately preceded by '6' (a number) and immediately followed by '\)' (a symbol). Thus, there is only one such number in the series.
To determine what happens when acid is mixed with water, we need to recall the definition of an acid and its behavior in an aqueous solution. Acids are substances that donate protons (HβΊ ions) when dissolved in water. These protons then combine with water molecules to form hydronium ions.
Correct Option: A) It will increase the concentration of hydronium ions per unit volume.
The problem describes a relationship between letter groups based on the English alphabetical order. We need to identify the pattern in the given examples and then apply the same pattern to find the related group for "JIBP". The pattern usually involves a consistent shift (addition or subtraction) in the alphabetical position of each letter.
This question tests knowledge of current affairs related to India's monetary policy. Specifically, it asks about the repo rate declared by the Reserve Bank of India's Monetary Policy Committee (MPC) on a specific date. To answer this, one needs to be aware of the latest announcements made by the RBI regarding key policy rates.
Correct Option: D) The Reserve Bank of India's Monetary Policy Committee (MPC) maintained the repo rate at 6.50% in its October 2024 meeting, which would include the declaration on October 9, 2024.
If cosβ΄θ − sinβ΄θ = k, then the value of \(\frac{1-k}{1+k}\) is:
The problem requires us to find the value of an expression involving \(k\), where \(k\) is defined by a trigonometric identity. We will use algebraic identities and fundamental trigonometric identities to simplify the given expression for \(k\) and then substitute it into the target expression.
Given the equation:
\[ \cos^4\theta - \sin^4\theta = k \]Recognize the left side as a difference of squares, \(a^2 - b^2 = (a-b)(a+b)\), where \(a = \cos^2\theta\) and \(b = \sin^2\theta\):
\[ (\cos^2\theta - \sin^2\theta)(\cos^2\theta + \sin^2\theta) = k \]Apply the fundamental trigonometric identity \(\cos^2\theta + \sin^2\theta = 1\):
\[ (\cos^2\theta - \sin^2\theta)(1) = k \]\[ \cos^2\theta - \sin^2\theta = k \]Now we need to find the value of \(\frac{1-k}{1+k}\). Substitute the expression for \(k\):
\[ \frac{1 - (\cos^2\theta - \sin^2\theta)}{1 + (\cos^2\theta - \sin^2\theta)} \]Simplify the numerator:
\[ 1 - \cos^2\theta + \sin^2\theta \]\[ (\sin^2\theta + \cos^2\theta) - \cos^2\theta + \sin^2\theta \]\[ 2\sin^2\theta \]Alternatively, using \(1 - \cos^2\theta = \sin^2\theta\):\[ \sin^2\theta + \sin^2\theta = 2\sin^2\theta \]Simplify the denominator:
\[ 1 + \cos^2\theta - \sin^2\theta \]\[ (\sin^2\theta + \cos^2\theta) + \cos^2\theta - \sin^2\theta \]\[ 2\cos^2\theta \]Alternatively, using \(1 - \sin^2\theta = \cos^2\theta\):\[ \cos^2\theta + \cos^2\theta = 2\cos^2\theta \]Substitute the simplified numerator and denominator back into the expression:
\[ \frac{2\sin^2\theta}{2\cos^2\theta} \]Cancel out the 2s and use the identity \(\frac{\sin\theta}{\cos\theta} = \tan\theta\):
\[ \frac{\sin^2\theta}{\cos^2\theta} = \tan^2\theta \]Correct Option: A) \(\tan^2\theta\)
This is a coding-decoding problem based on alphabetical order. We need to identify the pattern or relationship between the given pairs of letter groups and then apply the same pattern to find the related group for the third given group.
B) INOM is the correct option because by adding 7 to the alphabetical position of each letter in BGHF, we get INOM.
The question asks us to identify the relationship between two statements: (I) Government authorities are looking for solutions to reduce air pollution, and (II) There has been an acute rise in asthma cases. We need to determine if one is a cause of the other, or if they are independent.
D) II is the cause and I is its possible effect. The increase in asthma cases (Statement II) is a health crisis, which is a strong reason for the government authorities to find solutions to reduce air pollution (Statement I), as air pollution is a known contributor to respiratory diseases like asthma. Thus, the rise in asthma cases is the cause, and the government's action is the effect.
