Type AB blood has both A and B antigens but no anti-A or anti-B antibodies. This means it can accept red blood cells from any blood type (A, B, AB, or O) without antibody-mediated rejection.

The Rh factor was discovered through research on Rhesus Macaques (Macaca mulatta). Scientists Landsteiner and Wiener found that rabbits injected with rhesus monkey red blood cells produced an antibody that also agglutinated human red cells.

Blood groups A, B, AB, and O are classified based on antigens present on red blood cells. Type A has A antigens, Type B has B antigens, Type AB has both, and Type O has neither. Antibodies in plasma determine compatibility, but antigens on RBCs define the type.

Genes for both A and B antigens are dominant over O. This means if a person inherits an A gene from one parent and a B gene from the other, they will have AB blood type (both antigens expressed). The O allele is recessive and only expressed when no A or B is present.

Multiplying 11 by itself: 11*11 = 121. This is a basic multiplication fact. Option A correctly shows this result.

Blood group inheritance follows ABO patterns. If father is A (genotype AA or AO) and mother is B (genotype BB or BO), their children can inherit: A from AO×BB or AO×BO; B from AA×BO or AO×BO; AB from any cross; O only from AO×BO. All four types are possible.

Father with blood group A (AA or AO) and mother with O (OO) can only pass A or O alleles. Children can be A (if father contributes A and mother contributes O) or O (if both contribute O). They cannot be B or AB since neither parent has a B allele.

When both parents have blood group O (genotype OO), they can only pass O alleles to their children. Therefore, their children can only have blood group O. Types A, B, and AB are impossible since no parent has those alleles.

Two B-type parents can have genotypes BB or BO. If both are BB, children are only B. If one or both are BO, they can have B or O children. Type A or AB is impossible since neither parent has an A allele.

35*35 = 1225. You can calculate this as 35² = (30+5)² = 900 + 300 + 25 = 1225. Option A is correct.

This is a famous Hindi couplet. The correct word is "mita" (erased/destroyed), meaning they cannot erase us from this world. The phrase emphasizes resilience against the world's power.

47*47 = 2209. You can verify this as 47² = (50-3)² = 2500 - 300 + 9 = 2209. Option C is correct.

43*43 = 1849. You can calculate as 43² = (40+3)² = 1600 + 240 + 9 = 1849. Option D is correct.

This is from the Gangs of Wasseypur soundtrack. The correct phrase is "Parwar digaar" meaning oppression/adversity. The line means people don't fear swords or bullets, but only oppression.

27*27 = 729. You can calculate as 27² = (30-3)² = 900 - 180 + 9 = 729. Option B is correct.

36 × 36 = 1296. You can calculate this as (30 + 6)² = 900 + 180 + 180 + 36 = 1296, or use the standard multiplication algorithm.

29 × 29 = 841. Calculate as (30 - 1)² = 900 - 60 + 1 = 841, or memorize that 29² is 841.

This completes the Hindi idiom about things not being child's play - 'bachon ke khelne ki cheez nahin'. The full idiom means that when a hand is cut, blood comes out - showing consequences.

This is the Hindi proverb 'People who live in glass houses shouldn't throw stones' - 'Jinke ghar sheeshe ke hon, woh dusron par pathar nahi phenka karte'. Glass houses can be easily damaged.

This is from the popular dialogue style where if you don't put your feet on the ground (work hard), you'll become 'melay' (soft/spoiled). The complete phrase suggests staying grounded.
