Fossilization
“Fossilization is released”
1. May be due to a mutation in the allele coding for white colour, which results in an allele coding for yellow colour in the flowers.
2. The original white flower that was isolated may have been heterozygous, Ww, where W codes for the white pigment in flowers, and W is dominant to w. The crossing of Ww × Ww will give offspring with genotypes of WW, Ww, Ww, ww, genotypic ratio of 1:2:1, and phenotypic ratio of 3 white :1 yellow. The offspring with the yellow flowers has a genotype of ww, homozygous recessive.
Hope this helps! :)
Answer:
33
Explanation:
because proton number is always equal to atomic number
Answer: .OH, O2-, H2O2
Explanation:
Reactive oxygen species (ROS) are chemically reactive and unstable species containing oxygen. ROS are formed when oxygen is partially reduced, thus they are all radicals with very high reactivity, attacking membrane proteins such as ion channels etc
Examples include peroxides (H2O2), superoxide (O2-), hydroxyl radical (.OH)
It is generally followed by cytokinesis which divides the cytoplasm and cell membrane
