Photosynthesis would be one, and respiratory chemistry would be another. But you could also consider the electro-chemical nature of the nerve synapses.
The greenhouse effect is essential to life on earth. The enhanced greenhouse effect is not. In fact if it is enhanced too quickly it can be harmful to life.
Essential conditions for life include a stable source of energy, a suitable environment with liquid water and a range of elements for chemical reactions, protection from harmful radiation, and the presence of organic molecules for building blocks of life. These conditions are necessary for sustaining life as we know it on Earth.
Water, or H2O, is the most common chemical compound on Earth. It is essential for life and is found in abundance in oceans, rivers, lakes, and even in the atmosphere in the form of water vapor.
grade 9 academic science ?? ;) anyhow... photosythesis should win the most important chemical reaction on earth "award" because if there was no photosynthesis, it would mean the end of plants generating oxygen. So therefore all living things would die because no living things can survive without oxygen!
Because it is in a very huge amount on earth i.e. 70% . . . . . . . . . . . . but only 3% of it is useful
Yes they are essential to life. If there are no chemical reaction in our body then our food are not digest and body can not get energy and if there are not chemical reaction in our environment then many usefull elements are not get etc etc
You think probable to photosynthesis.
No, oxygen is not a person or living being named Marybelle. Oxygen is a chemical element that is essential for supporting life on Earth.
Scientists hypothesize that chemical events preceded the origin of life on Earth because organic molecules, essential for life, can be formed through non-biological processes like chemical reactions and catalysis. Studying these chemical events can provide insights into how the building blocks of life may have formed on early Earth before biological processes took over.
nitrogen, oxygen, and water are nonmetals in the atmosphere, and their cobinations are essential for life on earth
Yes. That is true. Water is very good solvent for most of the minerals. Minerals are very essential for the life to sustain. Ions are formed out of minerals in water. Such ionization is essential for most of the chemical reaction to occur. The free flowing ions can readily interact to from new chemicals.
Chemical reaction help us in our daily life by / through make all task easier... -sEnA
i am not completely sure but i think it (chemical reaction) describes when two or more atoms bond together
water, air and blood
Sunlight and water.
a chemical reaction that happens once cannot be reversible while d one with lifewill continue to reproduce
The primary source of energy responsible for a larger portion of life on earth is the sun. Through photosynthesis, plants convert sunlight into chemical energy that supports the entire food chain, making sunlight essential for life on earth.
