All stars have their own EM radiation, which makes their EM spectrum and from that scientist can know if star is approaching us or going away from us by "Blue shift" and "Red Shift" respectively. By this spectrum, they also can find out anything about star like it's heat, light, temperature etc.
Hope this helps!
If using the trait representations of Gg for green hair, you would end up with two showing the heterozygous genotype of GG, and two showing the homozygous traits of gg.
When a cell divides, each daughter cell must receive its full complement of genetic material in the form of chromosomes containing DNA, or deoxyribonucleic acid. A chromosome is made up of two long strands of DNA and several types of proteins . A DNA strand is composed of a long backbone of sugar and phosphate units . One of our different nucleotide bases -- A, T, C or G -- hang off each sugar unit. The sequence of the bases encodes genetic information. The three steps in the process of DNA replication are initiation, elongation and termination
He discovered deoxyribonucleic acid are DNA in 1953. he was the first to determine its double helix structure.
Explanation:
Water density changes with temperature and salinity. Density is measured as mass (g) per unit of volume (cm³). Water is densest at 3.98°C and is least dense at 0°C (freezing point).
