The sentence "Why did she break the garden wall?" in the Active Voice can be transformed into the Passive Voice as:

D. Why was the garden wall broken by her?

This option correctly rephrases the original sentence in the Passive Voice while maintaining its meaning.

Answer: C. Always

Teresa is not a pleasant person. She is always in a bad mood.

Explanation:

• The sentence describes Teresa as an unpleasant person.
• To emphasize her unpleasantness, we need to choose the option that shows she is frequently in a bad mood.
• Option A "never" means she is not in a bad mood, which does not align with the description.
• Option B "seldom" means she is rarely in a bad mood, which also does not align with the description.
• Option C "always" means she is constantly in a bad mood, which emphasizes her unpleasantness and aligns with the description.
• Option D "none of the above" is not applicable since option C is the correct choice.

• लस्सी शब्द एक वचन है जो हमेशा इसी रूप में ही प्रयोग होता है। इसका अन्य कोई रूप नहीं होता। इसलिए इसका सही उत्तर विकल्प ‘कोई नहीं’ होगा।
• विशेष - द्रव्य की सूचना देने वाली द्रव्यसूचक संज्ञाओं का प्रयोग केवल एकवचन में ही होता है।

‘भूतकाल’ का अर्थ होता है बिता हुआ। क्रिया के जिस रूप से बीते हुए समय का पता चले उसे ‘भूतकाल’ कहते हैं। अथार्त जिस क्रिया से कार्य के समाप्त होने का पता चले उसे ‘भूतकाल’ कहते हैं। दिए गये वाक्य में पूर्णभूत भूतकाल है। पूर्ण भूतकाल के दौरान यह पता चलता है कि कार्य हो चुका है। दिए गये वाक्य में भी उसके खाना खाने की बात स्पष्ट हो रही है। अतः सही विकल्प पूर्णभूत है।

Checking Statement I:

As per hints, following arrangements can be formed

H > J > K > I > G > F

Clearly H earns the maximum amount.

Hence data in statement I is sufficient to answer the question.

Checking Statement I:

As per hints, following arrangements can be formed

H > J > K > I > G > F

Clearly H earns the maximum amount.

Hence data in statement II is sufficient to answer the question.

Here, the data in either Statement I or II alone is sufficient to answer the question.

Hence, Option C is correct.

Lion eats deer, cat eats mouse, hawk eats pigeon but pig does not eat piglet.

Osmosis is the process in which the passage of water goes from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.

Given, LCM = 225, HCF = 5,
First Number = 25 , Second Number = ?
We can find the Second Number with the help of given formula,
"LCM × HCF = 1st Number× 2nd Number"
⇒ 225 × 5 = 25 × 2nd Number

∴ 2nd Number = 45

The Taj Mahal, a symbol of eternal love, was commissioned by Shah Jahan in memory of his wife Mumtaz Mahal.

The Four Sights of an old man, a diseased person, an ascetic, and a dead person at the age of 29 moved Buddha to the path of renunciation.

Four circles of radius 5 cm are cut out.
Area cut = 4*(π5²) = 100π
Total area of circular sheet = π(20)² = 400π
Area uncut = 300 π
The ratio of uncut to cut portion is 3 : 1

∴ a_mn = a + (mn - 1) d = 1/mn + (mn - 1) 

we know that the line parallel to y axis is given by x = a

x-4 = 0

x = 4
so it is a line parallel to y axis, at a distance of 4 units from it, to the right.

X² - 3x - m(m+3) = 0

=> x² + mx - (m+3)x- m(m+3) = 0

=> x(x+m) - (m+3)(x+m) = 0

=> (x+m) (x-m-3) = 0

x = - m and m+3

Roots are - m and m+3

We have mean = 
Mean = 
Now each value is increased by 5
Mean = 
+5=65+5=70
Hence the mean is 70

No. of red face card = 6

Total no of cards = 52

Probability of getting a face card

= No. of red face cards/Total no. of cards

= 6/52 = 3/26

Given a cylinder with

Radius = 28 / 2 = 14 cm

Height = 20 cm

ii.) Total surface area = 2πr ( r + h )

= 2 x 22 / 7 x 14cm ( 14 + 20 )cm

= 2991.99cm2
=2992cm2
(b) 2992cm2 is the correct option.

Mirage is formed by total internal reflection in deserts where due to heating of earth, refraction index of air near the surface of earth becomes lesser than above it.

The image of the ink spot moves up by 1cm.

Refractive index = Real depth/ apparent depth

1.5 = 3/ apparent depth

Apparent depth = 3/1.5 = 2 cm

Distance through which the microscope is moved is 3 - 2 cm = 1 cm upwards

• An electric field exists in the electrolyte between the positive and negative terminals of the battery.
• In the external circuit, the current flows from the positive electrode to the negative electrode.
• To maintain continuity, in the electrolyte, the current (positive charges) flow from the negative electrode (lower potential) to the positive electrode (higher potential).
• Work done by the source in taking unit positive charge from lower to higher potential is called electromotive force.

Since we know that 1litre -1000ml 1ml-1\1000litre So,12ml-1/1000×12=12/1000 =0.012

Ionization isomers are identical except that a ligand has exchanged places with anion or neutral molecule that was originally outside the coordination complex.
Thus, in Ionization isomerism the central ion and the other ligands are identical.
So, according to the definition, Cl^- is replaced by NO^2- in the ionization sphere.
 [Cr(H₂O)₄Cl(NO₂)Cl] ---->  [Cr(H₂O)₄Cl(NO₂)]⁺ + Cl^-
[Cr(H₂O)₄Cl₂]NO₂ -----> [Cr(H₂O)₄Cl₂]⁺ + NO₂^-

Gustatory receptors detect taste while olfactory receptors detect smell.

The correct answer is:

c) Animals reproduce only by sexual mode of reproduction

Explanation:

• While many animals reproduce sexually, some animals can reproduce asexually. Examples include hydra (budding), planaria (regeneration), and some insects and reptiles (parthenogenesis).
• Therefore, it is incorrect to say that animals reproduce only by sexual reproduction.

The excretory system in humans functions to remove waste products from the body.

Mixed cropping and intercropping:
Mixed cropping and intercropping are two agricultural practices where multiple crops are grown simultaneously on the same field. While both methods involve growing multiple crops together, intercropping differs from mixed cropping in the following ways:
Different crops in different rows:
- In intercropping, the different crops are grown in different rows, alternating with each other. This means that the crops are not mixed randomly but are strategically placed in separate rows.
- This arrangement allows for better utilization of resources such as sunlight, water, and nutrients, as the crops have different growth patterns and requirements.
- It also helps to minimize competition between crops for resources, leading to higher overall yields.
Reducing risk and providing insurance:
- One of the main advantages of intercropping is that it reduces the risk of crop failure.
- By growing different crops together, farmers can spread their risk and have a backup in case one crop fails.
- This provides insurance against the failure of a single crop and helps to stabilize agricultural production.
Other benefits of intercropping:
- Intercropping also has other advantages such as increased biodiversity, pest and disease management, and improved soil health.
- The presence of multiple crops can attract different beneficial insects that help in natural pest control.
- Some crop combinations also have a synergistic effect, where the growth of one crop benefits the growth of another.
- Additionally, intercropping can help improve soil fertility by fixing nitrogen, reducing soil erosion, and enhancing nutrient cycling.
In summary, while both mixed cropping and intercropping involve growing multiple crops together, intercropping differs from mixed cropping by strategically arranging different crops in separate rows and providing risk reduction and insurance against crop failure. Intercropping also offers additional benefits such as increased biodiversity, pest management, and improved soil health.
