Question 142

IB MTS 2025• Test

The fluffiness of cakes and idlis is due to the release of carbon dioxide gas when baking soda reacts with which of the following?

  1. AOption (a)

    Salt

  2. BOption (b)

    Sugar

  3. COption (c)

    Oil

  4. DOption (d)

    Acid

View answer & explanation

Correct answer

Answer: (d)D.

Acid

Why this answer is correct

The correct answer is Acid.

Key Points

  • The fluffiness of cakes and idlis is due to the release of carbon dioxide (CO2) gas during a chemical reaction involving baking soda (sodium bicarbonate) and an acid.
  • When baking soda reacts with an acid (e.g., lemon juice, vinegar, or lactic acid in curd), CO2 gas is produced, which gets trapped in the batter, forming air pockets.
  • These air pockets expand upon heating, causing the batter to rise and resulting in a fluffy texture in cakes and idlis.
  • Common acidic ingredients used in baking include buttermilk, yogurt, vinegar, lemon juice, or cream of tartar.
  • This reaction is a part of leavening, a process that makes baked goods light and porous by introducing gases like CO2 into the batter or dough.

Additional Information

  • Salt
  • Salt (sodium chloride) is used in baking primarily to enhance the flavor of the final product.
  • It also strengthens the gluten structure in bread dough and regulates yeast fermentation, but it does not contribute to the production of carbon dioxide gas.
  • Sugar
  • Sugar is used in baking to add sweetness, create a tender texture, and contribute to browning during baking.
  • While sugar can interact with yeast in bread-making to produce CO2, it does not react with baking soda to release the gas required for fluffiness in cakes and idlis.
  • Oil
  • Oil is used in baking to improve the texture and moisture of the final product.
  • It does not contribute to the leavening process or the production of carbon dioxide gas.

Question 143

IB MTS 2025• Test

  1. AOption (a)

    Small Modular Reactors

  2. BOption (b)

    Fast Breeder Reactors

  3. COption (c)

    Fusion Energy Reactors

  4. DOption (d)

    Thorium-based Reactors

View answer & explanation

Correct answer

Answer: (a)A.

Small Modular Reactors

Why this answer is correct

The correct answer is Small Modular Reactors.

Key Points

  • Small Modular Reactors (SMRs) are advanced nuclear reactors with a capacity of up to 300 megawatts per unit, which is about one-third of the capacity of traditional nuclear power reactors.
  • The Union Budget 2025-26 highlighted the Nuclear Energy Mission to promote research and development of SMRs as part of India’s clean energy transition strategy.
  • SMRs are cost-effective, modular, and scalable, allowing for easier deployment in remote and smaller regions with lower electricity demand compared to traditional nuclear reactors.
  • These reactors are designed with enhanced safety features and can operate flexibly to complement renewable energy sources like wind and solar power.
  • The Indian government is focusing on SMRs to achieve net-zero emissions by 2070, reduce dependence on fossil fuels, and ensure energy security.

Additional Information

  • Fast Breeder Reactors (FBRs):
  • FBRs use fast neutrons to sustain the fission process and are capable of producing more fissile material than they consume.
  • India has been actively pursuing FBR technology with the construction of the Prototype Fast Breeder Reactor (PFBR) at Kalpakkam, Tamil Nadu.
  • These reactors are essential for utilizing thorium reserves and achieving a sustainable nuclear fuel cycle.
  • However, FBRs are not the focus of the 2025-26 Nuclear Energy Mission as they are part of India’s long-term nuclear program under its three-stage nuclear power strategy.
  • Fusion Energy Reactors:
  • Fusion energy reactors aim to replicate the process that powers the sun by fusing hydrogen isotopes to release vast amounts of energy.
  • Fusion is considered the “holy grail” of clean energy due to its virtually limitless fuel supply and minimal radioactive waste.
  • Currently, fusion energy is in the experimental phase, with international projects like ITER (International Thermonuclear Experimental Reactor) leading the charge.
  • India is a member of the ITER project, but commercial fusion energy reactors are not yet a feasible option for immediate implementation.
  • Thorium-based Reactors:
  • Thorium-based reactors use thorium as a fuel, which is abundant in India, to generate nuclear energy.
  • India has been investing in thorium-based reactor technology as part of its three-stage nuclear power program.
  • The Advanced Heavy Water Reactor (AHWR) is a notable project in this field.
  • Although thorium reactors hold great promise for India’s energy future, they are not the focus of the 2025-26 Nuclear Energy Mission.

Question 150

IB MTS 2025• Test

In humans, the determination of a child's sex is influenced by:

  1. AOption (a)

    father's gamete

  2. BOption (b)

    mother's gamete

  3. COption (c)

    blood group

  4. DOption (d)

    environmental factors

View answer & explanation

Correct answer

Answer: (a)A.

father's gamete

Why this answer is correct

The correct answer is father's gamete.

Key Points

  • In humans, the sex of a child is determined by the type of sex chromosome contributed by the father’s sperm cell during fertilization.
  • Humans have 23 pairs of chromosomes, including one pair of sex chromosomes. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY).
  • All egg cells (ova) produced by the mother carry an X chromosome, as females have only X chromosomes.
  • The sperm cells produced by males can carry either an X chromosome or a Y chromosome. If a sperm carrying an X chromosome fertilizes the egg, the child will be female (XX). If a sperm carrying a Y chromosome fertilizes the egg, the child will be male (XY).
  • Thus, the father’s gamete (sperm) determines the sex of the child, as it contributes either the X or Y chromosome.

Additional Information

  • Mother's gamete:
  • The mother’s gamete (egg) always carries an X chromosome, as females have two X chromosomes (XX).
  • While the mother’s gamete contributes half of the genetic material, it does not determine the child’s sex since it always provides an X chromosome.
  • Blood group:
  • The blood group of parents is determined by the ABO and Rh factor systems and is inherited independently of the sex chromosomes.
  • Blood group does not play a role in determining the sex of a child.
  • Environmental factors:
  • Environmental factors such as temperature, diet, and lifestyle can influence certain biological processes but do not affect the determination of a child’s sex in humans.
  • In some reptiles, environmental factors like temperature can influence sex determination.
