Correct Answer: users

Solution : The correct choice is the second option.

The word "users" is the appropriate option to fill in the blank.

The sentence suggests that habitat loss didn't receive much attention from the collective group of people using Twitter. In the context of the sentence, the term "Twitter users" refers to individuals who use the social media platform Twitter.

The meanings of the other options are as follows:

• Band: It refers to a musical group or a group of people with a common purpose.

Correct Answer: Tamil Nadu

Solution : The correct option is Tamil Nadu.

The first state in India that mandates rooftop rainwater harvesting systems for every home is Tamil Nadu. The act of collecting and storing rainwater as opposed to letting it run off is called rainwater harvesting. Rainwater is collected from a surface that resembles a roof and channelled to a tank, deep pit, or reservoir with percolation so that it seeps down and replenishes the groundwater.

Correct Answer: 166

Solution : Given:
49 × 7 ÷ 13 – 87 + 12 = ?

On, interchanging the symbols with each other, we get –
= 49 ÷ 7 × 13 + 87 – 12
= 7 × 13 + 87 – 12
= 91 + 87 – 12
= 166

So, 166 is the required answer to the given equation. Hence, the second option is correct.

Correct Answer: $2 \sec A$

Solution : $\frac{1-\sin A}{\cos A}+\frac{\cos A}{1-\sin A}$
$=\frac{(1-\sin A)^2+\cos^2A}{\cos A(1-\sin A)}$
$=\frac{1+\sin^2 A-2\sin A+\cos^2A}{\cos A(1-\sin A)}$
$=\frac{1+1 -2\sin A}{\cos A(1-\sin A)}$
$=\frac{2 -2\sin A}{\cos A(1-\sin A)}$
$=\frac{2(1 -\sin A)}{\cos A(1-\sin A)}$
$=\frac{2}{\cos A}$
$=2\sec A$
Hence, the correct answer is $2\sec A$.

Correct Answer:

Solution : As per the mirror image properties, closer things appear closer to the mirror in the reflection.
Here, according to the information provided, the mirror is placed on the right side of the figure (on line MN). So, the left side of the reflected image will appear as the right side, and the right side will appear as the left side. However, the top and bottom of the reflected image will remain the same.
Thus, the correct mirror image of the given figure will be –

Hence, the third option is correct.

Correct Answer: Haryana

Solution : The correct answer is Haryana.

Haryana celebrates the Gugga Naumi festival during the lunar month of Bhadon. It is observed from August through September and is associated with snake worship. This festival honours Gugga Pir, who also happens to be in Bhadon. The northern Indian states of Punjab, Haryana, and a few others celebrate Guga Naumi.

Correct Answer: Turnaround time

Solution : The correct answer is Turnaround time.

In the context of batch processing or task scheduling systems, turnaround time refers to the time between program input and output. The complete process from submitting a task or program for processing through waiting (if necessary), executing the work and obtaining the output or results is included in the turnaround time. Shorter turnaround times are often preferable since they indicate faster work execution and more efficient resource utilisation.

Correct Answer: 12

Solution : The correct option is 12.

Each kho-kho team consists of twelve players, but only nine players take the field once during a match. There are two innings in a game. In an inning, each team gets seven minutes to attack and seven minutes to defend.

Correct Answer: Loss 1%

Solution : Marked price, $MP$ = INR 550
Cost price, $CP=\frac{MP\times 100}{(100+10)}$
= $\frac{550\times 100}{(110)}$
= INR 500
Selling price after 10% discount on marked price, $SP = \frac{550\times (100-10)}{100}$
 = $\frac{550\times 90}{100}$
 = INR 495
Now, loss percentage = $\frac{(CP-SP)}{CP}\times 100$
= $\frac{(CP-SP)}{CP}\times 100$
= $\frac{(500-495)}{500}\times 100$
= 1%
Hence, the correct answer is 'Loss 1%'.

Correct Answer: Actin and Myosin

Solution : The correct option is - Actin and myosin.

The contractile proteins in a muscle refer primarily to two types of proteins: actin and myosin. Actin is a globular protein that forms thin filaments in muscle fibers. These filaments are involved in muscle contraction by sliding over myosin filaments. Actin is also important in various cellular processes like cell division, cell motility, and the maintenance of cell shape. Myosin is a motor protein that makes up the thick filaments in muscle fibers. It plays a central role in muscle contraction. Myosin molecules have a head region that can bind to actin, and a tail region that interacts with other myosin molecules to form the thick filament.
