Explanation:

• The correct option is 4 Sub-mucosa, It contains nerves and blood vessels. 
• The wall of the alimentary canal from oesophagus to rectum possesses four layers namely serosa, muscularis, sub-mucosa, and mucosa.
• Serosa: The serosa is the outermost layer and is made up of a thin mesothelium (epithelium of visceral organs) with some connective tissues. It is also called tunica adventitia in the oesophagus.
• Muscularis: Muscularis is formed by smooth muscles usually arranged into an inner circular and an outer longitudinal layer. An oblique muscle layer may be present in some regions.
• Sub-mucosa: The submucosal layer is formed of loose connective tissues containing nerves, blood, and lymph vessels. In the duodenum, glands are also present in the sub-mucosa.
• Mucosa: It is the innermost layer of the gut that contains the secretory and absorptive cells. This layer forms irregular folds (rugae) in the stomach and small finger-like foldings called villi in the small intestine. It is differentiated into 3 parts:

1. The outer part called mucosa muscularis: It is made up of longitudinal and circular muscles. It has an important role in exposing surface area for the absorption
2. The middle part called lamina propria. It contains few modified lymphatic tissues which provide immunity. Eg. peyer's patches.
3. The innermost part called the mucosal layer.

Given:

The ratio of number when 5 subtracted to it and 2 added to it is 5 ∶ 7

Concept used:

Basic Concept of ratio and proportion

Calculation:

Le the number be x

∴ When 5 is subtracted to it the number is (x - 5) and when 2 added to it the number will be (x + 2)

Now, the ratio is 5 ∶ 7

∴ (x - 5)/(x + 2) = 5/7

⇒ 2X = 45

⇒ X = 22.5

Hence, option (2) is correct.

The logic followed here is:

So, '-15' will complete the series.

Hence, the correct answer is "Option 3".

The correct answer is Australia.

Key Points

The following things have been borrowed from the Constitution of Australia:

1. Concurrent List.
2. Freedom of trade.
3. Commerce and intercourse.
4. The joint sitting of the two Houses of Parliament.

Additional Information

• The other borrowed provisions from different countries and details of those are given in below:

The correct answer is Concave mirror.

• A concave mirror or converging mirror is a spherical mirror, which has a reflecting surface which bends inwards.

Key Points

• They reflect and focus incoming light rays at a point which is called the focus point.
• A concave mirror is used as a reflector in torches, searchlights, headlights of motor vehicles, etc. to get a powerful parallel beam of light. 
• This helps us to see things up to a considerable distance in the darkness of night.
• Some dental mirrors also use a concave surface to provide a magnified image.

Given:

Diagonal of cube = √27 cm

Formula used:

Diagonal of a cube = √3 × a

The total surface area of cube = 6 × side²

Here, a → side of the cube 

Calculation :

As, diagonal of cube = √27 cm

Let, the side of the cube be 'a'

√3 × a = √27

⇒ √3 × a = 3√3

⇒ a = 3 cm

Total surface area of Cube = 6 × side² = 6 × 3² = 6 × 9 = 54 cm²

∴ The total surface area of the cube is 54 cm².

The correct answer is 1-C, 2-B, 3-D, 4-A.

Key Points

• Kalibangan:
  • Kalibangan is an archaeological site at Hanumangarh in Rajasthan near the Ghaggar river. 
  • Plough field, fire altars, bones of camel, burial in the circular and rectangular grave is found here. 
• Chahundaro:
  • Chahundaro is an archaeological site at Sindh in Pakistan near the Indus river.
  • we can find a bead factory and ornaments here which points towards good craftsmen in this area. 
  • No fortified structure in this place. 
  • It is the only Harappan city without a Citadel and evidence of human sacrifice is available here.
• Surkotda:
  • Surkotada is an Indus Valley Civilisation archaeological site located in Rapar Taluka of Kutch district, Gujarat. 
  • It is a smaller fortified Indus Valley Civilisation site with 1.4 hectares (3.5 acres) in area.
  • Bones of horse and graveyard are found at Surkotda in Gujarat. 
• Mohenjodaro:
  • It is a planned settlement that is divided into two sections, one smaller but higher (Citadel) and the other much larger but lower (Lower Town).
  • The Citadel owes its height to the fact that buildings were constructed on mud-brick platforms.
    • It was walled, which meant that it was physically separated from the Lower Town.
    • It had structures that were probably used for special public purposes.
  • The Lower Town was also walled. Several buildings were built on platforms, which served as foundations

According to the given information :

Seven boys, B1, B2, B3, B4, B7, B8, and B9 are standing in a straight line, facing South.

• Only two boys stood to the left of B1.
• Only three boys stood between B7 and B1.

• B4 stood at one of the extreme end.
• B9 stood to the immediate right of B4.
• B3 stood in the middle of the row.
• B2 is not the immediate neighbor of B3.
  • Thus, the arrangement will be:

Clearly, 'Four boys stood to the right of B1' is the correct statement.

Hence, the correct answer is "Four boys stood to the right of B1".

Confusion Points

• Kindly note that the question asked is about total lobes in the lung 
• The right lung has 3 lobes
• The left lung has 2 lobes
• 3 + 2 = 5 
• Hence the answer is 5 lobes 

Key Points

• The right lung has three lobes and the left has two lobes. They are further divided into segments and then into lobules.
• The lungs are an essential organ that is necessary for the exchange of oxygen and carbon dioxide from the body.
  • The function of the lungs is to transport oxygen from the atmosphere into the bloodstream and to release carbon dioxide from the bloodstream into the atmosphere.
