Key Points

• Connective tissues provide structural support and integrity to the body, with diverse types such as loose, dense, adipose, cartilage, bone, and blood, each contributing unique properties and functions within the extracellular matrix. Hence, option 3 is the correct answer.
• The extracellular matrix, composed of protein fibres and ground substance, determines the flexibility, strength, and elasticity of connective tissues, allowing them to adapt to different mechanical demands.
• Apart from their structural roles, connective tissues also play a crucial role in immunity, with certain types housing immune cells and contribute to immune responses against pathogens and foreign substances.
• Connective tissues are essential components of the body, contributing to its overall architecture, supporting organs and tissues, storing energy, protecting vital structures, and participating in various physiological processes.​

Additional Information

• Blood:
  • Blood is a type of connective tissue that consists of cells suspended in a liquid matrix called plasma.
  • It plays a vital role in transporting oxygen, nutrients, hormones, and waste products throughout the body.
• Bone:
  • Bone is a specialized connective tissue that forms the skeletal structure of the body.
  • It provides support, protection, and facilitates movement.
  • Bone tissue is composed of cells called osteocytes embedded in a matrix of collagen fibres and calcium salts.
• Ligament:
  • Ligaments are fibrous connective tissues that connect bones to other bones in a joint.
  • They provide stability and help limit excessive movement within the joint, contributing to joint strength and function.

Key Points

• Sodium is a very reactive metal and combines explosively with air as well as water. Hence, they catch fire if kept open.
• Therefore, to prevent accidental fires and accidents, Sodium is stored immersed in kerosene oil.
• Sodium is a chemical element with the symbol Na (from Latin natrium) and atomic number 11.
• It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table.
• Its only stable isotope is 23Na. The free metal does not occur in nature and must be prepared from compounds.

Additional Information

• Reactivity series is a list of metals arranged in decreasing order of their reactivity. Most reactive metals are at the top while the least reactive metals are at the bottom.
• For any two metals in the series, the metal placed higher in the series can displace lower metals from their salt solution.

Concept Used:

A quadratic equation ax² + bx + c is a perfect square only when b² – 4ac = 0

Calculation:

⇒ x4 – 8x2 + m = (x²)² – 8x² + m

⇒ Let the value of x² be y

⇒ y² – 8y + m

⇒ On comparing with the standard equation, we get

⇒ a = 1, b = –8, c = m

⇒ For perfect square, b² – 4ac = 0

⇒ (–8)² – 4 × 1 × m = 0

⇒ 64 – 4m = 0

Hence, the required value of m is 16

The logic followed here is:

So, '209' will complete the series.

Hence, the correct answer is "Option 2".

The correct answer is Hampi.

Temple Type in India-

• According to the Shilpa Shastra, the temples of India can be classified into three types,
  • Nagara Style (North Indian Style)
  • Dravidian Style (South Indian Style)
  • Vesara Style (a hybrid of Northern & southern Style)
• The basic element of Hindu temple - 
  • Garbhagriha
  • Mandapa
  • Shikhara or vimana
  • Kalasha
• Temple Architecture in India -

Key Points

• According to physicist Albert Einstein's theory of relativity, nothing in the universe can travel faster than light.
• Only massless particles, such as the photons which constitute light, are capable of traveling at the speed of light ie approximately 3 lac km/sec.
• Any material item cannot be accelerated to the speed of light because for doing so we would require an unlimited amount of energy.
• The theory states that as matter approaches the speed of light, the matter's mass becomes infinite.
• It was introduced in Einstein's 1905 paper "On the Electrodynamics of Moving Bodies".
• It is based on two postulates which are contradictory to classical mechanics
  • The laws of physics are the same for all observers in any inertial frame of reference relative to one another (principle of relativity).
  • The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source.

Important Points

• The theory has many surprising results which led to other observations. Some of these are:
  • Relativity of simultaneity: Two events, simultaneous for one observer, may not be simultaneous for another observer if the observers are in relative motion.
  • Time dilation: Moving clocks are measured to tick more slowly than an observer's "stationary" clock.
  • Length contraction: Objects are measured to be shortened in the direction that they are moving with respect to the observer.
  • Maximum speed is finite: No physical object, message or field line can travel faster than the speed of light in a vacuum.
  • The effect of gravity can only travel through space at the speed of light, not faster or instantaneously.
  • Mass–energy equivalence: E = mc², energy and mass are equivalent and transmutable.

Additional Information

• Daltons Law
  • ​The total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual component gases.
  • P_total = P_a+P_b+P_c.......................so on.
• Corpuscular theory of light
  • ​In optics, the corpuscular theory of light, arguably set forward by Descartes in 1637.
  • It states that light is made up of small discrete particles called "corpuscles" (little particles) which travel in a straight line with a finite velocity and possess impetus.
• Henry Law
  • The weight of a gas dissolved by a liquid is proportional to the pressure of the gas upon the liquid.
  • Holds only for dilute solutions and low gas pressures.

The square of the numbers are

(66)² = 4356

(67)² = 4489

(68)² = 4624

So, the least number to be added = 4624 - 4523 = 101

Hence, the correct answer is "101".
