Question Discussion & Solution

The correct answer is connective.

• Blood is a type of connective tissue. 

Key Points

• ​Connective tissue
  • This is a kind of biological tissue that supports, connects, or separates different types of tissues and organs of the body.
  • Examples- Tendons, ligaments, cartilage, bone, blood.
• Blood has a fluid (liquid) matrix called plasma, in which red blood corpuscles (RBCs), white blood corpuscles (WBCs), and platelets are suspended.
  • The plasma contains proteins, salts, and hormones.
  • Blood flows and transports gases, digested food, hormones, and waste materials to different parts of the body.

Additional Information

• Epithelial tissue:
  • The epithelial tissues are formed by cells that cover the organ surface such as the surface of the skin, the airways, the reproductive tract, and the inner lining of the digestive tract.
• Muscular tissues:
  • Muscular tissue is a soft tissue that composes muscles.
  • Skeletal muscle (voluntary muscles), cardiac muscle (involuntary muscles) are examples of it.
• Nervous tissue:
  • The main components of the nervous system are the brain, spinal cord, and nerves which regulate and control body functions.
  • It is made up of neurons that have important functions in the nervous system.

CONCEPT:

• Force: The interaction which after applying on a body changes or try to change the state of motion or state of rest is called force.
• Force is denoted by F and the SI unit is Newton (N).

• Force (F) = Mass (m) × acceleration (a)

EXPLANATION:

• Both Dyne and Newton are units of force in the CGS and S.I system.
• Newton and dyne can also be written as (1 N = kg-m/s2) and (1 dyne = gm-cm/s2).
• The relation between the Newton and  Dyne is given as 

⇒ 1 N = 105 dyne

• Therefore, the ratio of SI unit and CGS unit of force is

\(\Rightarrow \frac{N}{Dyne} = 10^5\)

Explanation:

• The purpose of regression testing is to confirm that a recent program or code change has not adversely affected existing features.
• Regression testing is nothing but a full or partial selection of already executed test cases that are re-executed to ensure existing functionalities work fine.
• This testing is done to make sure that new code changes should not have side effects on the existing functionalities. It ensures that the old code still works once the new code changes are done.

The purpose of regression testing is to select test cases partially or fully to ensure existing functionalities work fine. Thus, regression testing is primarily related to functional testing

Need of Regression Testing

• Regression Testing is required when there is a change in requirements and code is modified according to the requirement or when one of the following has been done.
  • New feature is added to the software
  • Defect fixing
  • Performance issue fix

The correct answer is Article 44.

• Article 44 of the Constitution of India is related to the Uniform Civil Code for the citizens.

Key Points

• Directive Principles of State Policy (DPSP):
  • The Directive Principles of State Policy are described in Articles 36 to 51 in Part IV of the Constitution.
  • They embody the concept of a welfare state.
  • DPSPs are fundamental in the governance of the country.
  • DPSPs are non-equitable.
  • They apply to the Union and State Governments and all other authorities falling within the definition of 'State'.
  • This is a feature borrowed from the Constitution of Ireland.
  • Article 44: To secure a uniform civil code for all citizens throughout the country.

Additional Information

• Article 42: To make provision for just and humane conditions for work and maternity relief.
• Article 45: To provide early childhood care and education for all children until they complete the age of six years.
• Article 40: To organize village Panchayat of function as units of self-government.

Explanation:

• Pulses are considered to be nitrogen-fixing crops as they have root nodules onto which symbiotic nitrogen-fixing bacteria like Rhizobium get attached and fix atmospheric nitrogen
• Whereas, Cereals are the crops that demand a lot of nitrogen thus after harvest the soil becomes deficient in nitrogen, so to compensate for this deficiency a pulse crop is grown between two cereal crops
• This practice of growing different food crops alternatively in the same field is called Crop Rotation

Important Points 

Crop Rotation

• Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons
• It reduces reliance on one set of nutrients, pest and weed pressure, and the probability of developing resistant pests and weeds.
• Crop rotation involves planting a sequence of different kinds of crops in a location over a number of seasons.
• Rotating crops helps maintain or improve soil health and maintain or increase the productivity of the farm over time
• A diverse crop rotation gives the soil microbes different food sources, which ultimately makes soil healthier.
