A young goat has downward- curved horns. It's father has upward- curved horns while its mother has downward- curved horns. Which of these statements explains why the young goat has downward- curved horns?

The correct answer would be b) volume versus temperature, because they are also directly proportional.

If this is a true or galse then its true but if not then what is the question?

Answeropposite;

Radon-222 or rn-222 has a half-life of 3.82 days. to determine the fraction of an original sample of rn-222 that remains unchanged after 7.646 days, we calculate the amount of rn-222 remaining after 7.646 days and divide it with the original amount. using 1 gram as a basis and using half-life calculation methods, we can determine that  0.249 or 0.25  grams of rn-222 will remain, and thus the fraction remaining is 0.25 or 1/4.
