Answer: FOSSIL OF FISHES.
Explanation: The law of faunal succession, is based on the observation that sedimentary rock strata contain fossilized flora and fauna. These fossils succeed each other vertically in a specific, reliable order that can be identified over wide horizontal distances. According to this law, the order for animals is as follows; animals with shells; fishes; amphibians; reptiles; mammals; birds; humans.
-Fertility rate: The factor which affects the growth of the population in the biggest way is the fertility rate.
-Mortality rate: A key factor affecting the growth of the population is the death, or mortality, rate. Just as the birth of new people increases the population size, deaths decrease it.
-Immigration and Emigration: Cross-border migration is the act of people moving from one country to another. It affects the population size of both the host and destination countries. Emigration is caused by a number of factors, such as fleeing war, finding education, seeking new jobs or joining family members. When a person emigrates from a country, its population shrinks.
Answer:
The universe is expanding.
Explanation:
Following the theory that the universe was originated from a single heavily compressed and super hot point, and quickly expanded itself to what we see today, we can assume that the universe is still expanding.
According to the big bang theory, the remnants of that explosion still cause the planets and elements in the universe to move farther from one another, allowing the universe to continue its expansion. This expansion has become slower and slower over billion of years, and the scientific community doesn't know for sure if the expansion will go on forever, or if it will have an end.
