Answer:
D. They define geological periods because scientists use them as reference points for tracking the history of the earth.
Explanation:
Catastrophic events related to changes in geological timeline are very useful in defining geological periods.
These events have very significant appearance in the geological record and can be used to determine the history of the earth.
The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.
Geologists use these events that are often wide spread to delineate geological periods.
Answer:
The correct answer is ;
1. evolution.
2. growth and development
3. every living organism grows or develop
Explanation:
Fossils and traces and body remain provide information about the evolution of organisms and earth was found and how much it is change from then to modern organism and modern earth.
Comparing the skeleton of an adult horse to that of newborn foal provides the information of growth and development of the bones of foal to the adult horse.
Developing or growing is the property of life which is found in every living organism and comparison of the DNA sequence of Equus and Merychippus and draws conclusions about their genes and proteins isan example of this property.
Answer:
A) The positive linear relationship between body age and ammonia concentration only holds for early stages of decomposition.
Explanation:
The concentration of ammonia in the vitreous humor in the eyes of the cadavers has provided some considerable help in forence reports and other areas when it is necessary to know what was the postmortem interval of that body. However, this aid is only effective for a limited time because the positive linear relationship between body age and ammonia concentration is valid only for early stages of decomposition. After time has elapsed, this concentration is difficult to measure and the determination of postmortem time is impossible to determine.
