Somatic cells or body cells have a dipliod or full set of chromosomes. Gametes or sex cells, also called germ cells, have a hapliod number of chromosomes or half the number. Somatic cells are diploid cells, whereas the gametes are haploid cells. Meiosis does not take place during the production of somatic cells, whereas meiosis takes place during gametogenesis (production of gametes) giving rise to haploid cells. Somatic cells do not fuse during sexual reproduction, whereas gametes fuse during sexual reproduction giving rise to a diploid zygote.Somatic cells are found almost everywhere in the body, whereas gametes are restricted to certain parts
The organisms in a pond and the physical factors influencing them best describes an ecosystem.
It can be found in Mid-Altantic Ridge. The alternating magnetic stripes in the basaltic bedrock is an evidence of sea floor spreading. The lines in the basaltic rocks, follow whichever is the magnetic field on Earth during the time of eruption.
Reactions occur when two or more molecules interact and the molecules change. Bonds between atoms are broken and created to form new molecules.
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer huge quantities of carbon into the atmosphere. Extra carbon dioxide is lowering the ocean's pH.
