Answer:
iAiA or iAi = Type A
Explanation:
Blood group in humans is controlled by a gene with multiple alleles. The alleles iA and iB are co-dominant over one another but dominant over allele i. In the blood type:
iAiA or iAi - type A
iBiB or iBi - type B
iAiB - type AB
ii - type O
According to this question, a man and a woman have a child together. The mother's blood type is type O (ii) and the child's blood type is type A (iAi). This means that the father's blood type must be a type A with genotype "iAiA or iAi".
Answer: b. Light independent
Explanation: Photosynthesis is a process where carbohydrtes are formed with energy from the sunlight, in cianobacteria, algae and plants. This process has two steps:
- The first step are light dependent reactions where sunlight excites chlorophyll molecules and electrons are transport through photosystems. In this step, NADPH and oxygen are produced.
- The second step are light independent reactions called Calvin cycle, where CO2 is fixated to form carbohydrates using NADPH as energy source.
