Answer:
XᵇXᵇ
Explanation:
The X chromosome is the female sex chromosome and when you have a pair of X chromosomes (XX), then that would denote that the subject is female. Now when it comes to x-linked traits, for a female to be affected, she would have to have the allele on both chromosomes, or in this case, homozgous for color-blindness. (If it is found only on one, she would be a carrier, but she won't be affected.)
So the answer would be: XᵇXᵇ

I choose to research on artificial photosynthesis.
Explanation:
Artificial photosynthesis can be described as the a process in which the natural process of photosynthesis is bio mimicked. Sunlight, water and sugar are converted into carbohydrates and oxygen in artificial photosynthesis, just like the original process of photosynthesis.
Research in this department can be conducted to make devices which will produce solar fuels. The construction of of enzymes and to serve as microbial biofuel and biohydrogen production also need to be researched.
The Griess test uses chemicals to develop gunpowder residue patterns, particularly around bullet holes.
It is a scientific chemistry test which identifies the proximity of nitrite ion in liquid. One of its most significant applications is obtaining nitrite in drinking water. The test has also been extensively applied for the exposure of trace explosives comprising nitro groups. It is essential to release the nitrate ion from the nuclear explosive before the examination. This is commonly done by alkaline hydrolysis.
