You would want this observation to be in an area with a lot of biotic and abiotic factors, so the best place for it is an ecosystem.
The correct answer is - That some force lifted the rocks from the water.
The fact that there's sedimentary rocks on the tops of the mountains is an evidence that there has been some force that managed to lift upwards parts of the seafloor. Taking into consideration how slowly this force manages to lift up parts of the Earth, we can easily assume that the Earth is very old. The amount of time that is needed for a part of the seafloor to be lifted few thousand meters upwards is counted in tens of millions of years, thus giving us evidence that the Earth has been around for a very long time.
Answer:
B. Protein is composed of DNA which is produced in the cell
Explanation:
Answer: False.
Meat is a good source of protein. There are nine essential amino acids which are required under special conditions like illness.
These are- Histidine, Leucine, Isoleucine, Valine, Threonine, Methionine, Lysine, Phenylalanine and Tryptophan. They cannot be synthesized by the body and therefore need to be taken from external protein sources.
Since meat contains all the essential amino acids, therefore it is considered as a good source of protein. Hence, the given statement is false.
