The process that happens in the given statement above is the chemical evolution. The chemical evolution allows cells to generate where as when time prolongs or goes on, complex molecules are being created in which they came from simple molecules. They are being created because of the reactions that occur chemically, generating or evolving them as time goes by.
Answer:
Histone
Explanation:
Histones are the proteins that package the DNA in eukaryotes. DNA winds around a core of eight histones creating an structure called nucleosome that determines genome organization. Nucleosomes group and ungroup in an orderly manner allowing gene trasncription or silencing, respectively.
Single celled organisms such as amoebas, especially those that live in fresh water, continually gain water from their surrounding environment by osmosis. This water is pumped into a contractile vacuole which fills with fluid and periodically fuses with the cell membrane, releasing its contents to the exterior. Thus the amount of water actively transported out of the cell is equal to the amount of water entering the cell due to osmosis and there are no variations in the tonicity of the cell. This is homeostasis at a simple level. Without the contractile vacuole, the amoeba would continue to absorb water until its cytoplasmic contents were diluted to such an extent that metabolism no longer occurred and it would die.
Producing plastics benefits the economy by employing workers and it helps the economy of every state by spending billions of dollars on shipping plastic products.
Hope this helps! Have a good day.
Haploid and diploid chromosomes are two types of chromosomes present in cells. Then, both have differences with regard to the number of chromosomes. Of course, the number of chromosomes in the cell content.
Chromosomes are double helix structures, which then accommodate the DNA and proteins present in the cell. In other words, chromosomes are strands of DNA chains containing the genes in living organisms. Then as a container for DNA and cell protein.
Furthermore, it will help in packing DNA. There is a long homologous chromosome with a centromere position and the staining pattern is the same as the gene in the appropriate location characteristics.
