O nosso planeta é extremamente vasto e ainda está longe de ser completamente explorado. Curiosamente, a maior parte da superfíci

e terrestre é coberta de oceanos e eles permanecem um grande mistério para a humanidade. Pouco se conhece sobre as profundezas do oceano, mas durante a Segunda Guerra, devido ao uso de sonares para detectar submarinos, o homem conseguiu uma série de descobertas a respeito desse ambiente. A respeito dos oceanos, podemos dizer que:
a)os oceanos, apesar de serem extremamente vastos e robustos, possuem a maior parte da fauna em sua superfície, tendo as profundezas praticamente vazias de vida.

b)as profundezas do oceano são conhecidas por serem ambientes prósperos para a vida, com abundância de luz, alimento e poucos predadores, por isso muitos peixes e outras formas de vida habitam lá.

c)os oceanos são muito profundos, possuem um solo arenoso similar a de um deserto plano em seu fundo.

d)existem indícios de que áreas que hoje são oceanos antigamente eram superfície terrestre. Essas alterações podem ser atribuídas ao movimento tectônico das placas.

just olya [345]

Answer: Antigens

Explanation: The ABO system of blood grouping is based on the basis of the type of antigens that are present in the red blood cells. Erythrocytes is another name for the red blood cells. Antigens are molecules that are capable of eliciting immune response. There are two types of antigens: antigen A and B. Blood type A has only antigen A, blood type B has only antigen B, blood type AB has both antigen A and B while blood type O has no antigen (neither A nor B antigen).

Similarly, Rh trait is determined by the presence or absence of rhesus antigen in the erythrocytes. Rhesus antigen is an antigen first discovered in rhesus monkey. Rh+ indicates the presence of rhesus antigen in the red blood cells while Rh- indicates the absence of rhesus antigen in the red blood cells.
