Answer:
Type B+ can only receive blood from a donor that has blood type B and AB with Rhesus positive or negative.
Explanation:
The blood group system classification is based on the presence or the absence of antigens on the surface of the red blood cells. thus the blood group system is divided into four main blood group types/antigens present. During blood transfusion, the donated blood must be compatible with the patient blood type.
In blood transfusion, patient who is Rh positive can receive blood from donor who is Rh negative, but those with negative blood types cannot receive from anyone with a positive blood type but only the Rh- blood.
Donors with blood type A can donate blood to recipients with blood types A and AB
Donors with blood type B can give blood to recipients with blood types B and AB
Donors with blood type AB can donate to recipients with blood type AB only
Donors with blood type O can give blood to recipients with all blood types A, B, AB and O.
A star remarkably ruptured about 7,500 years ago established about 6,500 light years away. The explosion states that the star was brighter than million suns and it was visible during day light which amazed the Chinese astronomers. There were amazed at the appearance of the bright star. Many years later, the arrival of the telescope, astronomers launch a nebula which is a cloud like structure and that it is a remnant of a shattered star. The astronomers detected the promptly rotating neutron star - a pulsar surrounded by a gas envelope. Now Indian astronomers, combine powerful Cadmium-Zinc-Telluride imager on the on panel the indian astronomy satellite, AtroSat, have achieved the most absolute X-ray polarization measurement of the Crab nebula.
Answer
Water molecules sticking to a mirror’s surface is an example of adhesion.
Explanation
Adhesion is the property of attractive force that exist between two different molecules. water molecules adhere to other surfaces due to their polar nature.
Importance
it is because of adhesive forces that water can travel and cover a distance of 100 meter up in the plants through xylem vessels as recorded in the world tallest tree (red wood tree)
The best explanation for what do arteries, veins, and capillaries do is that they A - arteries normally carry oxygen-rich blood away from the heart, veins on the other hand generally carry oxygen-depleted blood back to the heart. Capillaries, however, deliver blood to individual cells.
Answer:
The given statements are True.
Explanation:
The particle of the matter through which a wave move or travels is called medium. The mechanical waves can be distinguished into three types on the basis of the movement of the medium when the energy of the mechanical wave passes through, are: transverse, longitudinal, and surface waves
A transverse wave: perpendicular to the direction that the wave
A longitudinal wave: parallel to the direction that the wave
