Answer:
(i) An allele is a variant of a gene, can either be short or tall.
Dominant = the tall allele that "trumps" the short allele. if a dominant and recessive allele is present (heterozygous) then the dominant phenotype will be shown.
(ii) David's eyes are Brown
(iii) Sarah's eyes are blue
(iv) David - B, b
Sarah - b, b
(v) Possible genotypes include Bb and bb. These give the phenotypes of brown eyes or blue eyes.
(vi) The chance for blue eyes is 50% (or 1:1 ratio)
The correct answer is - A. Photosynthesis.
Through the process of photosynthesis, the plants manage to use the sunlight, and combining it with the nutrients that they have got through their root system, they manage to produce glucose. Then they use the glucose by converting it to energy, which is crucial for their survival and proper growth, especially for their fruits, vegetables, seeds, spores.
This process is only able to occur with enough sunlight at disposal for the plant, and even if there's very small amount of nutrients gathered from the soil or water, the plants are still able to perform this process.
They say that is the individual who is a person who once lived but is now dead and studied genetics know as Gregor Mendel
