Carotenoids are organic pigments that are found in the chloroplasts and chromoplasts of plants and some other photosynthetic organisms, including some bacteria and some fungi. Carotenoids can be produced from fats and other basic organic metabolic building blocks by all these organisms.or the same reason, carotenoid colors often predominate in ripe fruit after being unmasked by the disappearance of chlorophyll. Carotenoids give the characteristic color to carrots, corn, canaries, and daffodils, as well as egg yolks, rutabagas, buttercups, and bananas.
The defining component of Linux is the Linux kernel, an operating system kernel first released on 5 October 1991 by Linus Torvalds. The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy.
Linux is a kernel. An operating system that uses the Linux kernel is known as a Linux distribution ('distro' in short). Some of these are also called GNU/Linux distributions because they mostly use GNU packages. Android is a popular exception, though. The Debian operating system is a GNU/Linux distribution. It is one of the earliest linux distros and is still popular to this day. It has served as a base for many other distros like Ubuntu, Mint, Kali, etc.
