B, proton is positive and it does not represent the symbol
The intensity of light had greater impact on the rate of photosynthesis. It was observed that the jar in which the intensity of light was high, large amount of oxygen was produced as compared to the jar in which the intensity of light was low.
In the process of photosynthesis, oxygen is produced from the carbon dioxide. As the oxygen in the jar increases, the leaf disk rises with in the jar which also signifies the higher oxygen production with higher rate of photosynthesis in presence of high intensity of light.
Answer: 25% of the offsprings will be heterozygous for both traits
Explanation: A cross between BbFf and bbff will yield 16 offsprings with four different possible genotypes: BbFf, Bbff, bbFf, and bbff. Only BbFf is the genotype that is heterozygous for both traits, and there are four offsprings with BbFf genotype.
Therefore the percentage of the offsprings that are heterozygous for both traits is 4/16 x 100 = 25%

The correct answer is a.
Even-aged practices remove larger groups of trees than uneven-aged management practices. Uneven-aged management is termed as the forest management whereby trees of different species are maintained for many sizes and ages to allow continuation of natural regeneration.
