Explanation

The desert ecosystem of Bhakkar and Mianwali districts in Punjab, Pakistan is known as the Thal Desert.

It is a sandy, arid region located between the Indus and Jhelum rivers.

Explanation

ax² − 2x + 2a = 0  

We are told: Sum of roots = Product of roots

Step 1: Use formulas  

For a quadratic equation ax² + bx + c = 0,  

- Sum of roots = −b/a

- Product of roots = c/a

So here:  

- Sum = −(−2)/a = 2/a  

- Product = (2a)/a = 2

Set them equal:  

2/a = 2

Multiply both sides by a:  

2 = 2a  

=> a = 1

Final Answer:  

a = 1

Explanation

In t-butyl alcohol, the tertiary carbon is bonded to no hydrogen atoms. 

A tertiary carbon is bonded to three other carbon atoms.

In t-butyl alcohol, the carbon with the OH group (the tertiary carbon

It is surrounded by three methyl groups, leaving no space for any hydrogen atoms to be attached directly to it. 

Explanation

The compound that is not a dehydrating agent is CaCl2 (hydrated calcium chloride). 

While anhydrous CaCl2 (calcium chloride) is a dehydrating agent, hydrated CaCl2 (calcium chloride with water molecules attached) does not have the same ability to absorb water. 

Explanation

Metatheria includes marsupials, which are distinguished by the presence of a marsupium (pouch) where young continue development after birth.

These animals give birth to underdeveloped young that crawl into the pouch to complete their growth.

Explanation

Two events A and B are independent if the occurrence of one does not affect the occurrence of the other.

This is mathematically defined as:

  P(A ∩ B) = P(A) × P(B)

Explanation

An address is an identifiable location in computer memory where data is stored.

Each memory cell has a unique address used to access or modify data.

Explanation

Ketones are formed by the oxidation of secondary alcohols, where the –OH group is bonded to a carbon attached to two other carbons.

Unlike primary alcohols (which give aldehydes), secondary alcohols yield ketones without further oxidation.

Explanation

Multiple ribosomes that are joined to the mRNA and contain developing polypeptide chains are known as polysomes.

Explanation

All non-zero digits and zeros between or after decimals are significant.

In 1.00110, all six digits (1, 0, 0, 1, 1, 0) are significant.
