Answer:

The correct answer is C. In the plaque assay for bacteriophages, the plaque is a clear zone caused by a zone of lysis.

Explanation:

The plaque assay is an approach used for titering bacteriophage stocks or determining the quantity of infectious virus in a sample. Plaques are visualized if you spot the phage on a lawn of growing compatible bacteria. Each plaque indicates an initial infection with one phage followed by lysis of neighboring bacteria in the lawn. Only viruses that cause visible damage of cells can be assayed in this way. The plaque assay is used to determine viral titer as plaque-forming units per ml so that known amounts of virus can be used to infect cells during subsequent work.

In the plaque assay for bacteriophages, the plaque is a clear zone caused by a zone of lysis.

Por qué se dice: ""Lo que le sucede a un individuo tiene su origen en una célula""
galina1969 [7]

Answer:

Esto es cierto porque una célula se define como la unidad básica, estructural y funcional de todas las formas de vida. La célula podría ser simple o compleja y contiene la información más importante sobre el individuo conocido como su ácido nucleico. El DNA controla la composición genética y física del individuo, coordina su comportamiento y garantiza que se adapte a lo largo de su vida. Esto hace que la célula sea crucial para la vida de un individuo. Los atributos físicos en el individuo, como la altura y el color de la piel, son controlados por la célula, mientras que también controlan los atributos genéticos, como el genotipo y el grupo sanguíneo.

A cross involving true-breeding, red snapdragons and true-breeding, white snapdragons produce all pink offspring because both ge
stiks02 [169]

Answer: The correct answer for the blanks are- 1) Dominant and 2) Blending of the trait.

Incomplete dominance produces a blend/ intermediate phenotype of both the parental phenotypes ( such as Pink snapdragon here) because none of the parental allele completely masks the effect of other.

As per the given information in the question, when true-breeding, red snapdragons are crossed with true-breeding white snapdragons, they produce pink colored offspring. This means that neither of the parental gene is dominant over the other.

When both are cross bred, they will represent a heterozygous state ( when alleles for both the snapdragons are present ), and they will produce an intermediate phenotype ( that is a blend of both the traits). This represents blending of the parental trait.
