Pancha Bhuta (/pəɲt͡ʃəbʱuːt̪ᵊ/ ,Sanskrit: पञ्चभूत; pañca bhūta), five elements, is a group of five basic elements, which, in Hinduism, is the basis of all cosmic creation. [1]
Life has been studied since ancient times, with theories such as Empedocles's materialism asserting that it was composed of four eternal elements, and Aristotle's hylomorphism asserting that living things have souls and embody both form and matter. Life originated at least 3.5 billion years ago, resulting in a universal common ancestor.
For instance, the Taittirīya Upaniṣad describes the five "sheaths" of a person (Sanskrit: puruṣa), starting with the grossest level of the five evolving great elements: From this very self did aether come into being; from aether, air; from air, fire; from fire, water, from water, the earth; from the earth, organisms; from organisms, foods ...
Selenium, which is an essential element for animals and prokaryotes and is a beneficial element for many plants, is the least-common of all the elements essential to life. [ 3 ] [ 63 ] Selenium acts as the catalytic center of several antioxidant enzymes, such as glutathione peroxidase , [ 11 ] and plays a wide variety of other biological roles .
Different elements can combine to form compounds such as water, which is fundamental to life. [32] Biochemistry is the study of chemical processes within and relating to living organisms . Molecular biology is the branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including molecular ...
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
Ecology – study of the interactions of living organisms with one another and with the non-living elements of their environment. Behavioral ecology – the study of the evolutionary basis for animal behavior due to ecological pressure; Ecosystem ecology – study of biotic and abiotic components of ecosystems and their interactions within an ...
Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...
