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.
Windows and Linux users are both dedicated to the operating systems that they use, but for new users, the decision between using Linux or Windows is one that has to be made. Both Windows and Linux are computer operating systems and both are designed to work on the same type of hardware (PCs or IBM compatibles). However, this is where the similarity between the two ends. One of the basic differences between Linux and Windows operating systems is that Linux is open source, meaning it is free under GNU. As a user, you get the Linux operating system for free (which is always a good thing) or at an inexpensive price, because it is carried by more than one distributor (Mandrake, Redhat, ect.).
