1 point 14. A scientist is using potassium-40, which is a radioactive isotope of
potassium, to discover the absolute age of a fossil by radiometric dating.
The scientist determines that about three-fourths of the original
potassium-40 atoms in the fossil now remain in the fossil. What additional
information is necessary for the scientist to determine the absolute age of
the fossil? *
the half-life of potassium-40
O O
the identity of an index fossil
the atomic mass of potassium-40
the total mass of the fossil

c.   the ratio of the mass of potassium-40 to stable potassium isotopes

Explanation:

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
