Photochemical smog results from automobile pollutants reacting with ultraviolet light from the sun. <span>Nitrogen oxides released from the automobile are introduced into the atmosphere reacts with sunlight to produce singular oxygen atoms. Oxygen atoms then combine with molecular oxygen to produce ozone which is one of the components of photochemical smog.</span>
In the light reactions, H2O goes in, and O2 goes out.
Percentage of human sperm cells carry an X chromosome is C 50%
The haploid number of the chromosomes should be 32.
Diploid number means that they have the complete sets of chromosomes in their cells, these cells are usually found in somatic (body) cells and different organisms have a different number. For example, a human somatic cell has 46 chromosomes, such as a muscle cell, or a skin cell etc.
Meanwhile, haploid number means that the number of chromosomes in the cell only have half of the chromosome number than that of the diploid cells. These haploid cells are usually found in gametes of sexually reproducing organisms, such as human, we have 23 chromosomes in our sex cells. This is important because we have to make sure the chromosome number of offsprings are not doubled, as during sexual reproduction, male and female gametes fuse together to form a zygote.
Therefore, to calculate the haploid number of a cell, we can divide the diploid number by 2, which is 64/2, and the answer would be 32.
