The logic here used is:

Hence, the missing number is '129'.

All beetles are insects and some beetles and some insects are black in colour.

The correct Venn diagram representation is,

Hence, option 2 is the correct answer.

From the given information:

Now we substitute the values in the given equation and solve it using BODMAS rule:

25 В 35 A 12 C 25 D 5 = ?
25 - 35 + 12 × 25 ÷ 5 = ?
25 - 35 + 12 × 5 = ?
25 - 35 + 60 = ?
85 - 35 = ?
50 = Answer

Hence the correct answer is option 2)

From the given open Dice:

7 and 2 is the opposite sides.

3 and 6 is the opposite sides.

4 and @ is the opposite sides.

And, two opposite sides can not be the adjacent surfaces, so it can't be shows in a dice.

Now,

Option 1) → Can not be made, because 4 and @ is the opposite sides.

Option 2) → Can not be made, because 7 and 2 is the opposite sides.

Option 3) → Can not be made, because 3 and 6 is the opposite sides

Option 4) → Can be made, because all the surfaces are adjacent sides.

Hence, the correct answer is "Option 4".

Draw the possible Venn diagram as per the statements.

Conclusions:

I. Some brown are pink → True (All pink are black and All black are brown)

II. All gold are black → False (No direct relationship given between gold and black, It may be possible but not definite)

III. Some gold are pink → False (No direct relationship given between gold and pink it may be possible but not definite)

So, 'Only conclusion I follows'.

Hence, "Option (2)" is the correct answer.

Logic:

Both the number should be added and then multiplied by the smaller number to get the required number.

For,

12 × 4 = 64

= 12 + 4

= 16

= 16 × 4 (As 4 is the smaller number between 12 and 4)

= 64

For,

14 × 5 = 95

= 14 + 5

= 19

= 19 × 5 (As 5 is the smaller number between 14 and 5)

= 95

For,

16 × 7 = ?

= 16 + 7

= 23

= 23 × 7 (As 7 is the smaller number between 16 and 7)

= 161

As, the obtained number is 161

Hence, the correct answer should be "161".

The correct answer is option 1.

In News

• Down To Earth: Save the carbon bubble: India’s voluntary carbon market must be regulated and made to contribute to its climate goals.

​Key Points
Carbon Bubble:

• The carbon bubble is a hypothesized bubble in the valuation of companies dependent on fossil-fuel-based energy production, resulting from future decreases in value of fossil fuel reserves as they become unusable in order to meet carbon budgets and recognition of negative externalities of carbon fuels which are not yet taken into account in a company's stock market valuation. Hence option 1 is correct.
• While most campaigns to reduce the investment, production, and use of fossil fuels has been based on ethical reasons, financial analysts, economists, and financial institutions have increasingly argued in favor of doing so for financial reasons. Thus, properly pricing fossil fuels based on the carbon bubble theory would mean renewable energy would be significantly more attractive to invest in, and therefore speed up the transition towards sustainable energy.
• Carbon Pricing – A carbon price is a cost put on carbon pollution to nudge polluters to lower the amount of greenhouse gas they release into the atmosphere.
• Carbon Tax – It is a form of Pollution Tax. It levies a fee on the production, distribution or use of fossil fuels based on how much carbon their combustion emits. It is a cost-effective tool to reduce greenhouse gas emissions in the atmosphere.
• Carbon Sequestration – the process of capturing waste carbon dioxide (CO2) from large point sources, such as fossil fuel power plants, etc. and depositing it where it will not enter the atmosphere.

Concept:

Surface Tension:

• Cohesive forces between the liquid molecules are responsible for the surface tension.
• Cohesive force can be defined as force of attraction between the two molecules of the same type.
• At the surface of water, the water molecules show stronger cohesive force than inside the water because there are no any water molecules over the surface. Therefore, cohesive force between adjacent water molecules increases.
• As cohesive force is increased, molecules try to come closer to each other and surface area of water surface decreases.
• Therefore, surface tension is generated, which also opposes the external forces acting on the surface of the water. For example, if we place a paper clip on the surface of water, it won't submerge in water even if it is made of steel.

Explanation:

• Due to surface tension, water molecules always try to minimize the surface area.
• In a spherical shape, surface area of water droplet is least among all the geometrical shapes for the volume of water present in it.
• Spherical shape also reduces the effect of external force acting on the water droplet.
• Therefore, surface tension on the surface of water molecule is maintained and water droplets maintain the spherical shape.
• Surface tension is given by,

Conclusion:

• Hence, surface tension of the water can be used to explain spherical shape of the water droplets.

Additional Information

• Water molecule have strong hydrogen bonding. It is one of the cohesive forces contribute to the surface tension of the water.
• As shown in the diagram below, oxygen being highly electronegative, involve itself into weak bonding with hydrogen of adjacent water molecule.

Additional Information

• The biggest regulator of oxygen affinity in Hemoglobin is the oxygen itself.
• If in the lungs, the oxygen levels are high the Hemoglobin shows a greater affinity towards the oxygen molecules, and as it bounds to more oxygen, this property of affinity increases and vice versa.
• When the Oxyhemoglobin binds to the maximum capacity, it becomes saturated but its affinity towards oxygen increases whereas when this binding loose oxygen molecule the affinity decreases.
• This regulation activity is called Cooperativity and is an important function as it allows the maximum amount of Hemoglobin to be carried to the tissues and also allows deoxyhemoglobin which is releasing the oxygen tissue.
