This mechanism allows killer T-cells to hunt down and destroy cells that are infected with germs or that have become cancerous.
The other main type of T-cells are called helper T-cells.
Helper T-cells orchestrate an immune response and play important roles in all arms of immunity.

Explanation:
The cross of a pea plant with round seeds (RR) with another pea plant with wrinkled seeds (rr) is shown as under :
P RR x rr
F1 Rr Rr Rr Rr
It is clear from the cross above, all the 4 probable progenies in filial 1 (F1) generation will be heterozygous with Rr genotype. Not even a single progeny will have homozygous recessive genotype which is responsible for producing wrinkled seeds. Also, even though the genotype of the progenies will be Rr not RR yet phenotypically they all will have round seeds i.e. they will show dominant trait. The reason behind it is that one of the alleles R which is responsible for dominant trait will mask the expression of recessive allele r. So, wrinkled phenotype which is a recessive trait will not be observed in any of the progenies.
True. Mendel studied hybrids by cross-fertilizing pea plants.
<h3>Mendel's experiment</h3>
Mendel performed several experiments to study how traits are inherited in living organisms. He used the pea plant as the reference organism.
Mendel was able to make several discoveries as far as trait inheritance is concerned. His works led to the law of inheritance - the law of segregation and the law of independent assortment of genes.
Mendel was able to achieve all these by carrying out cross-fertilization of pea plants based on different traits. For example, a pea plant that is true-breeding for wrinkle seeds was crossed with another pea plant that is true-breeding for smooth seeds.

I would say Ciprofloaxin then, E.coli is normally found in your gut but if it gets into your urinary tract it can cause a UTI. and UTI's are typically treated with Cipro
