Because there are 12 chromosomes in the sperm, it means that the grasshopper has 12 pairs of chromosomes. They would therefore have 12x2 chromosomes, or 24 chromosomes in total.he Diploid Number is usually twice that of the Haploid Number. Hence, since the sperm cells contains 12 chromosomes (Haploid), THE NUMBER OF CHROMOSOMES FROM A DIPLOID CELL WILL HAVE 24 CHROMOSOMES. Source(s): GCE O Level Candidate.
Mitral (MI-tral) valve prolapse (MVP) is a condition in which the heart's mitral valve doesn't work well. The flaps of the valve are floppy and don't close tightly. These flaps normally help seal or open the valve.
In mitral valve disease, the mitral valve, which is located between your left heart chambers (left atrium and left ventricle), doesn't work properly. Types of mitral valve disease include:Mitral valve regurgitation. In this condition, the flaps (leaflets) of the mitral valve don't close tightly, causing blood to leak backward into the left atrium of your heart. If not treated, it can result in heart muscle damage.The most common cause of blood leakage is mitral valve prolapse, in which the leaflets bulge back into the left atrium as your heart contracts. 1  Mitral valve stenosis. 2  In this condition, the flaps of the mitral valve become thick or stiff, and they may fuse together. Mitral valve stenosis. 2  In this condition, the flaps of the mitral valve become thick or stiff, and they may fuse together. 3  This results in a narrowed valve opening and reduced blood flow from the left atrium to the left ventricle.
