Asample has passed through 6 half-lives, what is the ratio of parent isotopes to daughter isotopes? a. 1 parent isotope for every 6 daughter isotopes b. 6 parent isotopes for every 1 daughter isotopes c. 1 parent isotope for every 64 daughter isotopes d. 1 parent isotope for every 63 daughter isotopes

Option C

Explanation:

After energy half life, a radioactive substance reduces its weight by half

After first half life, weight of the sample would be

After second half life, weight of the sample would be

After third half life, weight of the sample would be

After fourth half life, weight of the sample would be

After fifth half life, weight of the sample would be

After sixth half life, weight of the sample would be

Hence Option C is correct

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
