Explanation:
They both are alike because they both rely on frequencies to determine perception. In hearing, a sounds frequency determines its pitch whereas in TOUCH the frequency of vibrations is used to perceive texture and to sense the environment through hand held tools.
Answer:
a. all purple flowers in the F1 generation.
Explanation:
According to the given information, the allele for purple flower color (lets assume P) is dominant over while the allele of flower color (p). When two pure breeding purple (PP) and white flowered (pp) plants are crossed, the F1 would have all "purple flowered progeny with genotype Pp".
According to the Mendel's law of dominance, the hybrid genotype exhibits the dominant phenotype. Here, the allele "P" is dominant over allele "p". Hence, the genotype "Pp" would exhibit purple flower color and all the F1 progeny would have purple flowers.
The original source of phosphorus in a terrestrial ecosystem is soil microorganisms. soil becomes deficient in phosphorous leading to ecosystem retrogression. phosphorous can be found in our body, it builds strong bones and teeth.
hope it helps!
Answer:
The independent variable is "controlled" or held constant in the control group. A single experiment may include multiple experimental groups, which may all be compared against the control group. The purpose of having a control is to rule out other factors which may influence the results of an experiment.
