Answer:
ABO blood grouping system is based on presence or absence of three types of antigen on red blood cells. A and B blood group have A and B antigens respectively. AB blood group has both A and B antigens. O blood group does not have any antigen.
A body with particular blood type will consider other blood group foreign ( because it has different antigen ) and produce antibodies against it. A person with blood type A can not be given B type blood because the antibodies in his body will destroy RBCs with B antigen which may even prove fatal.
AB blood type person can receive blood from both A and B blood groups because he has antigens for both of them so it will produce antibodies for neither of them. He can also receive O type blood because O blood does not have any antigen so it can be given to any person without incompatibility reaction.
However, AB individual can only donate blood to AB individual because his blood cells have both A and B antigens. So, he can only donate blood to an individual who does not produce antibodies for both A and B blood groups and that would only be another AB blood type individual.
Answer The species is known from three individuals, all of which were found in the Habib Rahi Rock Formation of Pakistan
Maiacetus is significant because of how well the skeletons were preserved. Over 90% of the bones from the male were found intact, which is almost unheard of for a specimen this old!
Their skeletons have all been found among fossils of sea-creatures which suggests they lived in the sea.
The fore-snout is starting to elongate. An elongated fore-snout is found in all modern whales and all transitional whales after Maiacetus.
Answer:
1.Blood pressure in the small capillaries pushes the fluid into a sack called Bowman's capsule. 2. It reabsorbs important nutrients that are in the filtrate. 3. The Loop of Henle descends from the cortex into the medulla and concentrations of salts in the interstitium increases. 4. Salts leave the filtrate using both passive and active diffusion. 5. Waste products ammonia and urea are transported into the filtrate for excretion, while calcium and sodium continue to be reabsorbed and water leaves the nephron. 6. The filtrate empties into collecting ducts, where it combines with filtrate from other nephrons.
