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.
They use both there really isnt a big difference
Answer:
C. The rate of photosynthesis increases with an increase in carbon dioxide.
Explanation:
Photosynthesis, which is the process by which certain organisms obtain their food from the light provided by the sun, can be inhibited or promoted by certain factors. One of the reactants of the photosynthetic process is carbon dioxide (CO2), hence, an increase in the amount of carbon dioxide, increases the rate of photosynthesis.
According to this question, two areas with equal sunlight and available water are being described to have different levels or amounts of CO2. Area I has a high amount of atmospheric carbon dioxide while Area II has a low amount of atmospheric carbon dioxide. This means that Area 1 will undergo more photosynthetic activity than Area II.
