Septum pellucidum. Foramina are openings, not separations.
when the ventricles closes and between the atria and the ventricles.
First of all boot partition must be active by default or your system will not boot. Second, there is not such thing as a system partition. There is a system disk which is usually located on boot partition. If you are asking about whether you can change size of boot partition in cost of another partition the answer is yes. The best way to do that is to use one utilities designed for such purposes, for instance, Acronis Disk Director.
That depends on what primary partition the fourth extended partition has been placed on. If it was on the first primary partition, it would be /dev/sdb5 (or /dev/hdb5). If it was on the second primary partition, it would be /dev/sdb6 (or /dev/hdb6). If the third, /dev/sdb7, etc... Of course that's assuming you have placed all your logical partitions in a single primary partition. There are several other arrangements you could theoretically have made.
It is the 6th partition of you primary IDE hard drive. hd stands for hard disk ( Please note that in case of SCSI the names would be sd) Disks are numbered as hda, hdb, hdc and so on partitions are numbered as 1, 2, 3 and so on So hda1 is the first partition on first hard disk and hdb2 is the second partition on second hard disk.
First you need to find the manual for the minitool partition for the wizard.
sda1 is normally the one. It indicates the first disk's first patrition. if you have more than one disk or you put the system into, for example, the second disk's first patrition. Then the mbr will guide it to boot from sdb1.
Normal heart sounds (often called lub-dub) are caused by the pressure changes in the ventricles closing the various heart valves. The first sound, lub, is caused by the closing of the atrioventricular valves after the ventricles have filled with blood and as the ventricles begin to contract. The second sound, dub, is caused by the closing of the semilunar valves as the ventricles relax after pushing blood forward.
The ventricles
"A" and "B" are typically diskette drives. Many modern computers don't use diskettes any more, but the letters are still reserved. "C" is typically the first hard disk, or the first partition. "D" can be just about anything - it may be unassigned, it may be a second hard disk, a second partition on the first hard disk, a CD or DVD drive, or a USB drive.
2 Cell divisions. The first, meiosis I, separates the homologous chromosomes after allowing for crossing over. The second, meiosis II, separates each chromosome by splitting them by their telomeres!
The atrioventricular valves are two heart valves that allow for the transportation of blood from the atria to the ventricles of the heart. Its function is to prevent the return of blood to the atrium.
The heart makes a "lub-dub" sound. The first is when the AV valves close and the ventricles are filled. The second is when the semi-lunar vlaves close and the blood is sent to the lungs, or to the rest of the body.
