Explanation

Papaya is a dioecious plant, meaning male and female flowers are on separate plants, so it relies on cross-pollination.

In contrast, pea and tomato plants usually undergo self-pollination.

Explanation

To hear a distinct echo, the reflecting surface must be at least 17 meters away from the sound source.

This distance allows the sound to travel to the surface and back (total 34 meters) in 0.1 seconds, the minimum time gap for the human ear to perceive an echo.

Explanation

To find the maximum length of each piece, we need the HCF (Highest Common Factor) of 42, 54, and 64.

HCF of 42, 54, and 64 is 2 meters — the greatest length that divides all three without a remainder.

Explanation

On January 1, 2004, Pervez Musharraf secured a vote of confidence from Pakistan's National Assembly and Senate.

This allowed him to remain President until 2007 (a 5-year term under the 17th Constitutional Amendment).

Explanation

To factorize the equation:

a²b² - a² - b² + a

Rearrange the terms:

a²b² - b² - a² + a

Factor out common terms:

b²(a² - 1) - (a² - a)

Recognize the difference of squares:

b²(a + 1)(a - 1) - (a² - a)

Now, factor by grouping:

(a - 1)(ab² + b² - a)

Explanation

Explanation

Given y ∝ 1/x², we can write:

y = k/x²

Step 1: Find k

When y = 4 and x = 3:

4 = k/3²

k = 4 × 9

k = 36

Step 2: Find x when y = 9

9 = 36/x²

x² = 36/9

x² = 4

x = 2

Explanation

The Earth's layers include the crust, mantle, outer core, and inner core.

Magma is molten rock found within the mantle and crust, but it is not a distinct layer.

Explanation

The Cripps Mission (1942) offered dominion status after WWII, but was rejected by both the Indian National Congress and the Muslim League.

Gandhi called it a "post-dated cheque," and Jinnah also opposed it as it did not recognize the demand for Pakistan.
