Answer:
The father
Explanation:
Turner syndrome is a monosony condition resulting from the fusion of normal gamete with a gamete lacking a chromosome. The resulting zygote lacks in one chromosome. In human, Turner syndrome is deleterious in males and only occur in female.
Color blindness is a X-linked recessive trait. A male with XY chromosome will need just a copy of the allele while a normal XX female will need 2 copies (one from each parent). A X-0 female (Turner syndrome) only need a copy of the recessive allele.
Since both parents have normal vision, it means that the father was not affected for the disease and the affected X chromosome must have been from the carrier mother. It thus means that the missing X chromosome is the fault of the father.
<em>Therefore non-disjunction of the XY chromosome must have happened in the father leading to inability to contribute a X chromosome to the daughter.</em>

Answer:
A) CO₂ is converted in photosynthesis to carbohydrates.
Explanation:
Photosynthesis is the process wherein the phototrophs such as green plants fix the atmospheric carbon dioxide into organic nutrients (glucose). The oxygen gas is released as a by-product of the process.
During photosynthesis, the splitting of water is driven by solar energy and electron transport during light reactions produces ATP and NADPH. The ATP and NADPH drive the light-independent reactions of photosynthesis wherein the carbon dioxide gas is fixed into glucose.
For the purpose, the green plants absorb the carbon dioxide present in the air through stomata. The absorption of CO2 for photosynthesis keeps the atmospheric levels of the gas relatively constant.
