Answer:
The technique is known as "staining"
Explanation:
Staining is a technique used to enhance the color contrast of the microscopic samples when observed in the microscope especially in the microbiological samples.
In the given question, when the staining technique is used to identify the sample then staining procedure is followed in a process where the samples can be identified on the basis of the color contrast which is in the case of gram staining.
The gram staining is used to identify the bacteria on the basis of color as the bacteria which appear blue in color are called gram-positive and the bacteria which appear red in color are gram-negative bacteria.
Thus, staining is the correct answer.
It has increasingly got hotter
Answer:
The frequency of pink flowers will increase to near one over time, while the frequency of white flowers will decrease to near zero.
Explanation:
There are two forces acting as selective pressures.
- Slugs prefer to eat pink-flowering over white-flowering plants → selective pressure against the pink genotype → plants with pink flowers suffer from severe herbivory and are more likely to die.
- Bees prefer to pollinate pink over white flowers → selective pressure favoring the pink genotypes → Plants with pink flowers produce more seeds than plants with white flowers.
When the researcher removes all slugs from the study population, he/she eliminates the selective pressure against the pink genotype, leaving only the force acting in favor of the genotypes. So plants with pink flowers will produce more seeds that will originate more plants with pink flowers. As there is no predator over these plants, they will keep reproducing and growing pink flowers. Over time, the frequency of the pink genotype will increase, while the frequency of the white genotype will decrease.
Answer:
Mutation
Explanation:
the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. a distinct form resulting from a change in the structure of a gene.
