Pediculosis capitis, also known as hair lice, is one of the most common of ectoparasitic infections. This is highly contagious, especially in schools, day care centers, or areas wherein children are in close contact with infected children. In this case, the nurse should examine the heads of the children for small lice or nits on the hair shafts.
Answer: Experiment.
Explanation:
Suppose that we have two related variables, A (independent) and B (dependent)
We could design an experiment where we can manipulate the value of A at will, and we also can observe how the variable B changes.
This is called an experiment, where the objective is to see how the variable B is related to the variable A, and then try to make a model that explains this relationship.
B. Mesopela: the transmissive barrier through which two cell layers interact in the structure of the coral body
<span>They are composed into vesicles. They may also form lysosomes. Vesicles are packages with the main intent of transporting things out of and around the cell. Lysosomes help the cell digest its food. All vesicles are destined to be sent to a specific place inside the cell.</span>
If a dihybrid F1 plant, self-fertilizes, the F2 progeny will have two types of phenotypes. One would be the dominant trait phenotype for both the alleles, which would be possessed by 3/4th of the population.
Other would be recessive trait phenotype for both the alleles, which would be possessed by 1/4th of the population.
One fourth of the population would be true-breeding for the dominant traits.
Half of the population would be heterozygous for both traits and would have dominant phenotype
Rest one-fourth population would be homozygous for both recessive traits
