網頁Cells perform a huge number of different roles within your body. For example, epithelial cells protect the outside surface of the body as part of the skin and cover the organs and body cavities within. Bone cells build up bones to provide support for the body. Cells of the immune system fight invading bacteria. 網頁They include greater red blood cell volume and increased concentration of hemoglobin, the oxygen-carrying protein that is the main component of red blood cells. These changes allow somewhat higher levels of oxygen to circulate in the …

網頁In Summary: Expression of Genes. Gene regulation is the process of controlling which genes in a cell’s DNA are expressed (used to make a functional product such as a protein). Different cells in a multicellular organism may express very different sets of genes, even though they contain the same DNA. The set of genes expressed in a cell ...
網頁The two gametes (sperm and ovum) contain 23 chromosomes (n) each and when the sperm fertilizes the egg (ovum), the zygote now has a total of 46 chromosomes and becomes diploid (2n). This zygote then goes through many stages of the replication cycle to create more and more cells called somatic cells or body cells. diamond arcade building cubao網頁This is evidenced by human plasma calcium, which is one of the most closely regulated physiological variables in the human body.
