Biology is the overall natural science that studies life, with the other life sciences as its sub-disciplines. Some life sciences focus on a specific type of organism. For example, zoology is the study of animals, while botany is the study of plants. Other life sciences focus on aspects common to all or many life forms, such as anatomy and ...
Life is a quality that distinguishes matter that has biological processes, such as signaling and self-sustaining processes, from matter that does not. It is defined descriptively by the capacity for homeostasis, organisation, metabolism, growth, adaptation, response to stimuli, and reproduction.
eLS (previously known as the Encyclopedia of Life Sciences) is a reference work that covers the life sciences; it is published by Wiley-Blackwell. [1] As of June 2012, there were more than 4,800 article topics published in eLS online. eLS is updated monthly and over 400 articles are added to eLS each year. [citation needed]
Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, astronomy and Earth science. These branches of natural science may be further divided into more specialized branches (also known as fields).
The applications of biotechnology are diverse and have led to the development of products like life-saving drugs, biofuels, genetically modified crops, and innovative materials. [4] It has also been used to address environmental challenges, such as developing biodegradable plastics and using microorganisms to clean up contaminated sites.
Botanist – discipline of biology, is the science of plant life. Cognitive scientists – scientific study of the mind and its processes. Ecologist – scientific study of the relations that living organisms have with respect to each other and their natural environment. Entomologist – scientific study of insects, a branch of arthropodology.
Manufacturers of baby powder and cosmetic products made with talc will have to test them for asbestos under a proposal announced by the U.S. Food and Drug Administration.
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 ...
