The radioisotope, tritium 13(H) has a half-life of 12.3 years. If the initial amount of tritium is 32 mg, how many milligrams of it would remain after 49.2 years:
The radioisotope, tritium 13(H) has a half-life of 12.3 years. If the initial amount of tritium is 32 mg, how many milligrams of it would remain after 49.2 years:
1 mg
2 mg
4 mg
8 mg
The Correct Option is B
Solution and Explanation
N(t) = N₀\(\times\)(\(\frac{1}{2}\))(\(\frac{t}{T}\))
Given,
N₀ = 32 mg
t = 49.2 years
T = 12.3 year
Put these values into the formula:
N(49.2) = 32 mg\(\times\)(\(\frac{1}{2}\)) (\(\frac{49.2}{12.3}\))
N(49.2) = 32 mg\(\times\)(\(\frac{1}{2}\))(4)
N(49.2) = 32 mg\(\times\)(\(\frac{1}{16}\))
N(49.2) = 2 mg
So, after 49.2 years, there would be 2 mg of tritium remaining.
The correct answer is (B) 2 mg.

- RNA interference
- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025

Concepts Used:
Translocation of Solutes
- Translocation of organic solutes deals with the movement of organic food components or soluble solutes from one location to another in higher plants.
- These organic solutes include the soluble products of photosynthesis, amino acids, and other substances.
- It is a process that takes place in the sieve tubes with the help of adjacent companion cells in both upwards and downwards direction.
Downward translocation:
It is the transportation of the products of photosynthesis from the leaves to the stems and roots for consumption and storage. This process takes place in the sieve tubes with the help of adjacent companion cells.
Upward translocation:
It happens or occurs primarily during the germination of seeds, tubers, and other plants. When food is stored and converted into a soluble form, it is transported to the young seedling's upper growth section until it develops green leaves.
- Solutes are also moved upward from the stem to the branch's tip, where young leaves, buds, and flowers are found. Although translocation of organic solutes takes place through the phloem, under certain conditions, it may occur through the xylem.
