The following situations are presented to a medical examiner. in which situation is the medical examiner most likely to gather more evidence before determining the manner of death?

a) 18-year-old male recovered in alley with gunshot wound to back of head
b) 25-year-old male recovered from rapids after his empty kayak is sited by friends
c) 35-year-old male deceased at home from a drug overdose
d) 90-year-old female deceased at home with no external injuries

D)90-year-old female deceased at home with no external injuries

Explanation:

Option D has no evidence as to what caused the woman's death, so this option shows a case where the coroner will have to find out and collect a lot of evidence before indicating the cause of the woman's death. The other options make clear the cause of death, so these options are not the correct answer to that question.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
