Explanation

Isotope of Hydrogen:

Tritium (symbol ³H) is one of the three isotopes of hydrogen. 

Composition:

Its nucleus contains one proton and two neutrons. 

Instability:

The nucleus is unstable and decays by beta decay into helium-3, a stable isotope of helium. 

Radioactivity:

It is a radioactive material with a half-life of approximately 12.3 years. 

Production:

Tritium is produced naturally in the upper atmosphere by cosmic rays and also as a byproduct in nuclear reactors and nuclear weapons.

Explanation

Explanation

The new fringe width will be four times the original fringe width (quadrupled)

Because the formula for fringe width is directly proportional to the screen distance (D) and inversely proportional to the slit separation (d).

When the slit separation is halved (d/2) and the screen distance is doubled (2D), the fringe width increases by a factor of (2D / (d/2)) = 4. 

Explanation

After successful implantation in the uterus or an ovary (in the case of an ectopic pregnancy),

The embryo's trophoblast tissue begins to secrete human chorionic gonadotropin (hCG).

This hormone is essential because it maintains the corpus luteum, which continues to produce progesterone.

Progesterone is critical for maintaining the uterine lining and thus supporting the pregnancy. 

Explanation

Soda lime is a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO)

It is commonly used in decarboxylation reactions to remove the carboxyl group from a carboxylic acid molecule. 

Explanation

 An exothermic reaction means the system releases energy (heat) to its surroundings.

This is because the energy content of the products is less than the energy content of the reactants.

The surroundings then become warmer as a result of this heat release. 

Explanation

Lithium aluminium hydride (LiAlH₄) is a strong reducing agent.

It reduces carboxylic acids to primary alcohols effectively.

Explanation

The most abundant polymer on Earth is cellulose

Composition:

Cellulose is a polymer made up of glucose units. 

Natural Occurrence:

It is the primary structural component of plant cell walls, giving plants their rigidity and strength. 

Abundance:

It is the most abundant organic polymer on Earth, found extensively in plant life. 

Examples:

Cotton is a very pure form of cellulose, with a cellulose content of around 90%, while wood contains about 40-50%.

Explanation

• Marker of bone formation are Osteocalcin
• Bone Markers are Blood and Urine tests that detect products of bones.
• Osteocalcin is a protein that helps to regenerate bone tissue.
• All are important markers of bone formation except hydroxyproline which is a marker for wound healing.
