Article: With advances in medicinal chemistry, most modern antibacterials are semisynthetic modifications of various natural compounds. These include, for example, the beta-lactam antibiotics, which include the penicillins (produced by fungi in the genus Penicillium), the cephalosporins, and the carbapenems. Compounds that are still isolated from living organisms are the aminoglycosides, whereas other antibacterialsfor example, the sulfonamides, the quinolones, and the oxazolidinonesare produced solely by chemical synthesis. Many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units.[citation needed]

Question: What are the type of antibiotics which are taken from still living things?
Ans: aminoglycosides

Article: Samkhya philosophy includes a theory of gunas (qualities, innate tendencies, psyche). Guna, it states, are of three types: Sattva being good, compassionate, illuminating, positive, and constructive; Rajas guna is one of activity, chaotic, passion, impulsive, potentially good or bad; and Tamas being the quality of darkness, ignorance, destructive, lethargic, negative. Everything, all life forms and human beings, state Samkhya scholars, have these three gunas, but in different proportions. The interplay of these gunas defines the character of someone or something, of nature and determines the progress of life. Samkhya theorises a pluralism of souls (Jeevatmas) who possess consciousness, but denies the existence of Ishvara (God). Classical Samkhya is considered an atheist / non-theistic Hindu philosophy.

Question: Which state of guna is that of compassion, positiveness, and goodness?
Ans:
Sattva
