Genotype is the genetic basis of the organism. The individual letter in Tt represents the allele of the plant height trait.
Alleles are the variant form of the gene present at the same loci of the chromosome that codes for the specific trait of the organisms.

The correct answer is option B
The mining of uranium is harmful for both air and water. Uranium is a radioactive compound that is extracted by mining.
Uranium ore emits the gas named radon. The health effects of exposure to radon have particular problems. Significant rate of lungs cancer was observed during the 1940s and 1950s.
Water is used in the heap leaching of the uranium mining. The water can get mixed into the normal supply of water and harm the health of people.
Mining of the radioactive element Uranium has the following negative effects on both air and water such as contamination.
This is a a silvery-white metallic chemical element in the periodic table, with atomic number 92 and is commonly used to run nuclear power plant.
it exists in the air and when contaminates water could lead to kidneyailments in affected individuals which is why option B was chosen as the most appropriate choice.

Answer:
Sixteen years old is the age where the biggest difference between the average height of boys and girls can be observed. This is a difference of approximately 5.7 cm.
Explanation:
As we know, for biological reasons, boys and girls have different growths and different development in their bodies. However, the growth and development of boys and girls during childhood is very similar and only starts to look different even from adolescence, where individuals have great structural differences.
At 16 years of age, boys and girls have the greatest mean difference in height. While in previous years this difference was on average 1 centimeter, at 16 years old, girls are 150.8 cm tall on average, while boys are 156.5 cm tall.
