It's important because it helps you measure things. The prefixes are telling you the distance or meters, etc.
Answer:
When the sympathetic and parasympathetic systems are in balance, the tendency is to rest often and easily allowing for renewal and healing to the body. The balance between the two systems is a key step toward greater health and wellness!
Explanation:
Can you provide more specific details? I’m not even sure what this question is about.
The answer is 3:1.
If we imagine that plant has two alleles for the
trait, we can dominant allele represent with P represents and recessive allele with p. To get purebred monohybrid in the first generation, parents must be a dominant homozygote (PP) and a recessive hetero<span>zygote (pp):
Parental generation: PP x pp
The first generation: Pp Pp Pp Pp
Pp represents a heterozygote.
If we cross these heterozygotes:
The first generation: Pp x Pp
The second generation: PP Pp Pp pp
If dominant allele determines the phenotype, there will be 3 plants (one PP and two Pp) with one phenotype and only 1 plant </span><span>(pp)</span> with another phenotype and vice versa.
Answer:
directional selection
Explanation:
The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. <em>Biston betularia</em>, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.
