Answer:
The correct answer is option d) "head-on".
Explanation:
In hunting, the head-on angle refers to a position at which the hunter and the prey are face to face. This shot angle rarely results in a clean kill, ruins a lot of meat, and provides an animal the best opportunity to detect the hunter as the animal is in front of the hunter. At the head-on angle it is harder for the hunter to kill an animal with the first shot and ruins a lot of meat because the animal produces hormones such as adrenaline result of the stress.

Answer:
After 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
Explanation:
The half-life of a radioactive isotope of an element is the time taken for half the atoms present in a given amount of the element to undergo decay or disintegration. For example, the half-life of carbon-14 isotope is 5730 years. This means that, if there are 100 atoms of carbon-14 present in a given sample of a material, in the next 5730 years, approximately, 50 atoms of carbon-14 will be left in the material.
Since the half-life of radioactive isotopes are constant, these radioactive isotopes are used in the determining the ages of ancient life-forms as well as rocks.
In the given example, after 6000 years, approximately 500 atoms of carbon-14 will be left in the femur bone of an animal which had 1000 atoms of carbon-14 when the animal died.
