Answer:DNA is the hereditary molecule that determines hair color in humans, However, the DNA molecule itself is colorless
Explanation:
Answer:
An absorption spectrum illustrates the spectrum of light or electromagnetic radiation absorbed by the plant. This relies upon the molecular and cellular build-up of the plant. An action spectrum illustrates the spectrum of electromagnetic radiation most efficient for photosynthesis.
The action spectrum of photosynthesis monitors the absorption spectrum of chlorophyll. The absorption spectrum suggests that how much of each wavelength chlorophyll will captivate, while the action potential can indicate to us about the wavelengths that are most operative for photosynthesis.
Answer:
The options are incomplete, however, the question can still be answered based on general understanding. The possible gametes are:
GK, Gk, gK and gk
Explanation:
This question involved two different genes coding for leaf color and stem length respectively. In the first gene, the allele for green color is 'G' while the allele for yellow color is 'g'. In the second gene, the allele for long stem is 'K' while the allele for short stem is 'k'.
According to this question, a scientist is preparing a Punnett square for a dihybrid cross of a plant with a genotype GgKk. Based on Mendel's law of SEGREGATION, this plant with genotype: GgKk will undergo meiosis where the alleles of each gene will separate into possible gametes as follows:
GK, Gk, gK and gk
Note that, only one allele of each gene is present in each gamete.
Nitrogen-fixing bacteria fix atmospheric nitrogen to ammonia, which can then be taken up by plants.
- The process is called biological nitrogen fixation.
- Rhizobium, Azotobacter, cyanobacteria are some examples of nitrogen-fixing bacteria, which may be free-living or symbiotic.
