biotechnology, the use of biology to solve problems and make useful products. The most prominent area of biotechnology is the production of therapeutic proteins and other drugs through genetic engineering.History of biotechnology People have been harnessing biological processes to improve their quality of...
Darwinalso pointed out the same fact that only those species which have a high“biological fitness”, i.e. the ability to adapt to changes in one’s environment, will be selected by nature to pass on their genes to the next generation. So, adaptations are basically the results ofnatural ...
of the normal flora colonizing the human skin, nose, and other body parts. Most of the time, it will bring no harm but can become infectious or cause disease when it gains entry through an open wound. Conversely, the termfrank (true) pathogenspertains to infectious agents thatalwayscause ...
After failure of at least one TNF inhibitor, the response rate of biological agents is 20-40% after adjustment for the placebo response. In addition, the response may decrease over time in some patients. Finally, only a few patients achieve remission or low disease activity, the rate being ...
For example, mucins are the primary components of the mucous membrane. Some mucins are retained in the membrane while a few are released into the extracellular matrix. Mucins lubricate epithelial tissue and trap pathogenic agents. What is the function of a glycoprotein? Some of the functions of ...
new ways to improve biopesticides; coupled with the probability of low profits and financial rewards, companies are reluctant to invest much in this area. Additionally, there are regulatory constraints that come with the production and distribution of biopesticides, as they are biological agents. ...
Examples of amphipathic molecules include surfactants, phospholipids, and bile acids. The cell uses amphipathic molecules to construct biological membranes and as antibacterial and antifungal agents. Amphipathic molecules find commercial use as cleaning agents. ...
In this field of study, there is a subdiscipline bioethics which focuses on the interaction between ethical principles and biological functions. Generally, bioethics is used to more narrowly refer to biomedical ethics, which is concerned with the interaction between ethical principles and health....
• Waste decomposition (one of the most essential microbial process happening in soil) • Crop pollination (performed by agents such as bees that contribute to the reproduction of flowering plants) • Water and air purification and regulation ...
It is formed by the process of ionization and plays several important roles in the biological world. Anions are negatively charged ions whereas cations are positively charged ions. Etymology: The word ion originated in the mid-19th century from the Greek word ‘ienai’ meaning ‘go’....
