During photosynthesis, the water molecule is broken into hydrogen and oxygen. The hydrogen atoms are used to form a carrier molecule called NADPH that, later in the photosynthesis process, is broken down to form glucose, a sugar that organisms commonly use for energy.
What is the MBR. The MBR (stands for âMaster boot recordâ) is a boot sector (a region of your hard disk) that holds information about the partitions of your hard drive and acts as a loader for the operating system youâre running. The Master boot record is created when you first install Windows, on the first partition you create. Itâs the first 512 bytes of your hard disk. If the MBR is damaged, you wonât be able to boot into Windows. All Windows versions â Windows XP, Vista, 7 or 8 â use MBR and, if damaged you wonât be able to boot.
Stage 2: MBR loading. Once the BIOS gives control back to CPU, it will try to load MBR of the first boot device(We will consider it as HDD). MBR is a small part of Hard Disk with just a size of 512 Bytes, I repeat its just 512 Bytes.
