The fossil evidence found in these sedimentary layers best implies that animals evolved bony skeletons after shells
Explanation:
Fossil is not only describing when organism lived, but it also gives information about the “progression and evolution of life” on this earth over millions of years. Fossils also give information that previous life in earth is different from present life.
According to evolutionist around 500 million years ago complex internal skeleton organism came into existence. They told fish had firstly evolved and they dominated the sea. Fossilization is very rare process.

Explanation:
Ruminant animals chew the cud and that is mostly done by bovines such as cows and as well as buffaloes etc.
Answer:
The two components that helps to maintain the homeostasis of the cell are 1 Buffer system 2 Membrane transport process
Explanation:
1 Buffer system Buffer system helps to maintain a constant PH in addition to small amount of acid or base .There are many buffer system present inside our body
A Bicarbonate buffer system helps to maintain concentration of carbon di oxide, bicarbonate ion and Carbonic acid according to our body"s need.
B Phosphate buffer system
C Hemoglobin buffer system This buffer system helps too maintain normal O2/CO2 ratio of our body which is very much important of maintain our body"s homeostasis.
2 Membrane Transport process Various ion channels of plasma membrane sych as Na+ K+ ATPase,Ca2+ATPase ,H+ ATPase helps maintain ionic homeostasis of our body.
Answer: It is Hypertonic solution.
Explanation:
Hypertonic solution is a solution in which the the solutes Concentration outside the cells is greater than solute concentration inside the cell. When a cell is in Hypertonic solution, water will move out of the cell and it will shrivel. The cell will shrinks or cremated and may eventually die.
