Answer:
metabolism
Explanation:
Metabolism is a chemical reaction that involves break down of compounds to simple molecules that provide energy or synthesis of compounds. Metabolism can be classified into two; catabolism and anabolism.
Catabolism is the break down of componds through a cascade of events to provide energy in form of ATP, NADP. Anabolism is the the synthesis of compounds using energy released during catabolism to form complex structures. An example of catabolism is glycolysis and anabolism is the formation of proteins etc.
Answer:
it includes geological processes that slowly alter the layout of the physical enviroment and human activity such as land conversion which can help and alter much faster and causes the extinction of many species
Helium is an element with an atomic number of 2 which means that it has 2 protons in its core. So if any atom has 2 protons in its core, they it's helium no matter what.
On the periodic table of elements which I have attached in the image provided, the whole numbers in the tile tell you the number of protons. So helium is a noble gas which is found in the top right of the periodic table and I have drawn an arrow the atomic number which is the number of protons.
