Buffalo milk is whiter than cow milk. Why?
  • Beta-carotene pigment gets converted to colorless pigment
  • It contains more fat
  • It contains no lactose
  • It contains more calcium
✅Explanation: Buffalo milk appears whiter than cow milk due to the conversion of beta-carotene pigment to a colorless pigment. Beta-carotene, which is present in the milk, is responsible for the yellowish color. In buffalo milk, an enzyme present in the milk called beta-carotene reductase converts beta-carotene to colorless compounds, resulting in a whiter appearance. Cow milk, on the other hand, retains more of the beta-carotene pigment, contributing to a slightly yellowish hue.

  • Homogenization
  • Sterilization
  • Pasteurization
  • Calcification
✅Explanation: The process of breaking fat globules into uniform sizes in milk is called homogenization. Homogenization is a mechanical process that reduces the size of fat globules in milk, creating a more uniform distribution. This prevents cream separation and improves the texture and stability of dairy products. During homogenization, milk is forced through a fine nozzle under high pressure, breaking down the fat globules into smaller particles that remain dispersed throughout the milk.
Anammox is one of the steps of?
  • N Cycle
  • H Cycle
  • C Cycle
  • S Cycle
✅Explanation: Anammox, which stands for Anaerobic Ammonium Oxidation, is a step in the nitrogen cycle (N Cycle).

  • External breakdown
✅Explanation: The disorder described, where the arils of pomegranate become soft and discolored without external symptoms, is known as Internal breakdown of Pomegranate. This condition is not easily identifiable externally, making it challenging to detect until the fruit is cut open, revealing the undesirable changes in texture and color within the arils. Internal breakdown can be influenced by factors such as storage conditions, handling practices, and the physiological characteristics of the pomegranate variety.
Parallel and anti-parallel lines in a DNA helix are connected with which bond?
  • Hydrogen bond
  • Covalent
  • Phosphate bond
  • Carbon bond
✅Explanation: The structure of the DNA helix involves hydrogen bonds between complementary base pairs. The two strands of DNA run in opposite directions, creating a structure known as anti-parallel. The hydrogen bonds form between specific base pairs: adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). These hydrogen bonds between the complementary bases contribute to the stability and integrity of the DNA double helix.
Sugarcane ratooning compared to a pure crop?
  • More N required
  • Less N required
  • More P required
  • More K required
✅Explanation: In sugarcane ratooning, where a new crop grows from the stubble of the previous crop, there is typically an increased demand for nitrogen (N). Ratooning involves the regrowth of the sugarcane plant from the residual stubble after the main crop has been harvested. Since the plant is re-growing, it requires additional nitrogen to support the vigorous vegetative growth during the ratooning phase. Therefore, compared to a pure crop, sugarcane ratooning often requires more nitrogen for optimal growth and yield.
