În secţia de transplant renal a unui spital, un pacient este supus unei intervenţii chirurgicale. Acest pacient are nevoie de transfuzie cu o cantitate mică de sânge. La spital s-au prezentat rude ale pacientului, în vederea donării de
sânge. Ţinând cont de faptul că pacientul are grupa sanguină B, precizaţi următoarele:
a) aglutinogenul/antigenul şi aglutinina/anticorpul caracteristice grupei sanguine a pacientului;
b) două exemple de grupe sanguine pe care ar trebui să le aibă rudele pacientului, în vederea donării de sânge
necesar transfuziei; motivaţi răspunsul dat;
c) consecinţa în cazul transfuziei cu sânge provenit de la un donator incompatibil din punctul de vedere al sistemului
Rh.
d) Completaţi această problemă cu o altă cerinţă pe care o formulaţi voi, folosind informaţii ştiinţifice specifice
biologiei; rezolvaţi cerinţa pe care aţi propus-o.

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
