A scientist wants to determine the age of a rock. The rock contains an index fossil and an ancient relative of a living organism. Which is more useful for dating the rock, and why?

an ancient relative of a living organism would be more useful for dating the rock because fossils in a rock layer represent what lived during the period the rock was deposited.

Ancient Relative of a living organism

Explanation: Ancient Relative because by using the index fossil, you are also using the law of superposition. This law does not give you an accurate/specific date but instead the order they are in (i.e me saying i am older than my siblings compared to me saying i am 2 years older than them). By using an ancient relative of a living thing then we can see its phylogenic tree and measure around how old it is. Fossils also hold carbon and chemicals in there bones which allows us to use carbon dating. Carbon dating is an accurate way of measuring age.

answer: glucose is broken down

explanation:

cellular respiration is a three stage process your body undergoes to produce atp. the first of these stages is called glycolysis.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
