'ABA' plays a regulatory role in many physiological processes in plants. Abscisic acid is a growth inhibitor. It slows plant growth. Hence, the combination will show the slowest growth.

Cardiac muscles are involuntary, branched, cylindrical and uninucleated.

Arthropoda: It is a phylum of triploblastic, haemocoelomic, bilateral symmetry, segmented invertebrates having head, thorax and abdomen, a chitinous exoskeleton and jointed legs and appendages.

Spirogyra is a filamentous green algae that can often form green aggregates in freshwater ponds.

The characteristics given in the question are that of a monocot plant. There are no secondary vascular tissues in a monocot plant. Flower parts are present in multiples of three in monocots.

Artificial selection is the intentional reproduction of individuals in a population that have desirable traits. Example includes the production of cabbage, broccoli and cauliflower from a wild cabbage species.

Analogous organs are organs with different structure and same function. An example of an analogous trait would be the wings of insects, bats and birds that evolved independently but all of these perform the same function of flying.

Trichoderma is a fungus that is also used as a fungicide. It is used for foliar application, seed treatment and soil treatment for suppression of various disease-causing fungal pathogens.The other three are used as biofertilisers.

In a test cross, F₁ hybrid is crossed back with the recessive parent. In other words, test cross is the cross between a dominant phenotype (TT or Tt of first filial generation) and a homozygous recessive parent (tt).

Wuchereria brancrofti is a nematode which causes Elephantiasis. The major causal organism of acne is Staphylococcus bacteria.

Pancreatic juice is a liquid secreted by the pancreas, which contains a variety of enzymes, including trypsinogen, chymotrypsinogen, elastase, carboxypeptidase, pancreatic lipase, nucleases and amylase. Pepsin is not present in pancreatic juice.

All pteridophytes have a true alternation of generations, in which a dominant sporophyte generation (diploid) produces spores through meiosis, and a free-living gametophyte generation forms gametes (egg and sperm) by mitosis. The sperms are motile in pteridophytes.

Given time → 120 minutes (2 hours)
Number of bacteria given → 10
Each bacteria divides into two after 20 minutes.
So in 2 hours, the bacteria will divide 6 times.
After 120 minutes → 640 bacteria [2⁶ x 10] will be produced.

Out of the following, brass (alloy) is a homogeneous mixture of two metals named copper (70%) and zinc (30%). While milk, smoke and face cream are examples of heterogeneous mixtures because they are colloidal and their components are separated by physical means.

(1) Graphite is soft and slippery because there are only weak intermolecular forces between its layers.
(2) Graphite is a good conductor of heat and electricity because it contains delocalised electrons. These electrons are free to move through the structure of the graphite.
(3) Diamond is a good conductor of heat because all the electrons are close together due to a strong bond between the atoms causing vibrations.
(4) Both diamond and graphite are allotropes of carbon. They have different physical properties as both have different structures but same chemical properties.

According to the given information,
X + Y → colourless and odourless gas which turns lime water milky
Therefore, evolved gas is CO₂.
and X + CH₃OH → sweet smelling substance (ester)
Hence, 'X' should be carboxylic acid which reacts with alcohol in the presence of conc. H₂SO₄ to give sweet smelling ester through esterification reaction.
Among the given, C₂H₄O₂ is the molecular formula of acetic acid (CH₃COOH).

Frequency of a source remains constant as it depends on the source itself.

Speed of the sound in water is more than the speed in air. So, water acts as a rare medium and air acts as a denser medium for sound.

So, when sound travels from water to air, the wavelength will decrease as speed is given by v = λf.

Possible remainders for natural number =

⇒ 1³ = 1 → r₁ = 1
⇒ 2³ = 8 → r₂ = 8
⇒ 3³ = 27 → r₃ = 0
⇒ 4³ = 64 → r₄ = 1
⇒ 5³ = 125 → r₅ = 8
⇒ 6³ = 216 → r₆ = 0

Hence sum all possible remainders = 1 + 8 = 9

p(x) = q(x) (x – 1) + 3 (given)
p(x) = k(x) (x – 3) + 5 (given)
Also, p(x) = (x – 1)(x – 3) + r(x)
For x = 1,
p(1) = r(3)
⇒ 3 = r(1)
For x = 3,
⇒ p(3) = r(3)
5 = r(3)
Suppose r(x) = Ax + B
r(1) = A + B = 3
and, r(3) = 3A + B = 5
∴ A = 1 and B = 2
r(x) = Ax + B
⇒ r(–2) = –2A + B
⇒ r(–2) = –2(1) + 2
⇒ r(–2) = –2 + 2
⇒ r(–2) = 0

Possible roots for α,β ∈ -ve.

So, the total possible values of 'b' will be 12.

Let sides of the solid brick be x, 2x and 3x.
Volume = Number of bricks = 6x³
Let
x = 1, 6 × 1 = 6
x = 2, 6 × 8 = 48
x = 3, 6 × 27 = 222
x = 4, 6 × 64 = 384
x = 5, 6 × 125 = 750
At x = 5, number of cubes is going above 400.
Hence maximum number used = 384.

For same remainder 2272 - 875 is divisible by that number
⇒ 2272 – 875 = 1397, is exactly divisible by N.
Since, 1397 = 11 x 127

∴ The required 3–digit number is 127, which is divisible by 1397
Hence the sum of digits of 127 = 10.

Here, P(x) = x² + 5kx + k² + 5
and P(– 2) = 0
P(– 3) ≠ 0
∴ 4 – 10k + k² + 5 = 0
⇒ k² – 10k + 9 = 0
⇒ (k – 9) (k – 1) = 0
⇒ k = 1, 9 …….(1)
Also, P(– 3) ≠ 0
⇒ 9 – 15k + k² + 5 ≠ 0
⇒ k² – 15k + 14 ≠ 0
⇒ (k – 14)(k – 1) ≠ 0
⇒ k ≠14, 1 ..…..(2)
From (1) and (2), we get
k = 9

Suppose price of apples, bananas and coconuts be x, y and z, respectively.
2x + 3y + z = 26 .……(1)
3x + 2y + 2z = 35 …….(2)
(1) × 3, (2) × 2
12x + 13y + 7z = 78

Therefore, the cost of 12 apples, 13 bananas and 7 coconuts is Rs. 148.

Napoleon invaded Italy - 1797

Liberals wanted a nation which tolerated all religions since European states discriminated in favour of one religion or the other. Liberals opposed the uncontrolled power of dynastic rulers. They wanted to safeguard the rights of individuals against governments. They argued for a representative, elected parliamentary government, subject to laws interpreted by a well trained judiciary that was independent of rulers and officials. However, they were not democrats. They did not believe in universal adult franchise. They also did not want the women to vote.

In the seventeenth century, Bombay was a group of seven islands under Portuguese control. In 1661, control of the islands was passed into British hands after the marriage of Britain's King Charles II to the Portuguese princess.

Option 3 is wrong because Chinese did not developed printing to facilitate their trade

The impact of the Great Depression was particularly severe in Germany, which had enjoyed five years of artificial prosperity, propped up by American loans and goodwill. Unemployment hit millions of Germans, as companies shut down or downsized. Others lost their savings as banks folded.

The Weimar Republic was very fragile due to some inherent defects, one of which was Article 48, which gave the President the powers to impose emergency, suspend civil rights and rule by decree.

Both statements are true, but statement II is not the correct explanation of Statement I

The 1878 Act divided forests into three categories: reserved, protected and village forests. The best forests were called 'reserved forests'. Villagers could not take anything from these forests, even for their own use. For house building or fuel, they could take wood from protected or village forests.

They were known as Best forests but they were not intended for people's use. Hence statement II is false.

Shifting cultuivation was banned after forest laws were enacted

Cricket was a colonial game, limited to countries that had once been part of the British empire. It was started in England. The pre-industrial oddness of cricket made it a hard game to export. It took root only in countries that the British conquered and ruled.

Mahatma Gandhi wanted everyone to have clothes but not loincloth. He discarded his topi and vest and contended himself with loincloth. But he did not want to use this dress all his life and only wanted to 'experiment for a month or two'. But soon he saw this as his duty to the poor, and he never wore any other dress. He consciously rejected the well known clothes of the Indian ascetic and adopted the dress of the poorest Indian.

The most powerful weapon of the Spanish conquerors was not a conventional military weapon at all. It was the germs such as those of smallpox that they carried on their person. Because of their long isolation, America's original inhabitants had no immunity against these diseases that came from Europe. Smallpox in particular proved a deadly killer. Once introduced, it spread deep into the continent, ahead even of any Europeans reaching there. It killed and decimated whole communities, paving the way for conquest.

The silk routes are a good example of vibrant pre-modern trade and cultural links between distant parts of the world. Early Christian missionaries almost certainly travelled this route to Asia, as did early Muslim preachers a few centuries later.

The French built canals and draining lands in the Mekong Delta to increase cultivation. The vast system of irrigation works – canals and earthworks – built mainly with forced labour, increased rice production and allowed the export of rice to the international market. Vietnam exported two-thirds of its rice production and by 1931 had become the third largest exporter of rice in the world.

Both statements are correct, but statement II is not the correct explanation of statement I.
