Answer:
Mark pathogenic cells for destruction. (Ans. B)
Explanation:
Antibodies are generated by the plasma cells, and once these secreted, they attach quickly to the surface of the toxin and stop the toxin from infecting the normal body cell by blocking key extracellular sites.
Antibodies also help to mark pathogens for destruction by the help of macrophages or neutrophils and they are known as phagocytic cells because they are highly excited to macro-molecules complexed with antibodies.
The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy., i.e., option A.
<h3>What is heterozygous?</h3>
The occurrence of different types of alleles is referred to as heterozygous condition.
A heterozygous genotype may consist of one normal allele and one mutated allele, or two distinct mutated alleles.
The missing options of the question are:
- Yy ´ yy
- YY ´ yy
- Yy ´ Yy
- yy ´ yy
The cross between parent plants if one is heterozygous for yellow pods and the other is homzygous for green pods - Yy yy.
Thus, the correct option is A.
