In biochemistry, aligand is a substance that forms a complex with a biomolecule to serve abiological purpose. In protein-ligandbinding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein.
Receptor mediated endocytosis is an endocytotic mechanism in which specific molecules are ingested into the cell. The specificity results from a receptor-ligand interaction. Receptors on the plasma membrane of the target tissue will specifically bind to ligands on the outside of the cell. An endocytotic process occurs and the ligand is ingested.
A very well studied example of receptor mediated endocytosis involves the metabolism of cholesterol.
Umm where is the questions ?
The Correct answer is option B. Professional.
The professional association works for the interest of the individuals working in a particular field.The AMA or American Medical Association is a professional body, which works for the interests and the advocacy of the physicians or the medical professionals.
The AMA publishes the peer reviewed research papers. It also advocates for the interest of the physicians. All the physicians and the resident physicians can apply for the membership of the AMA, medical students can also apply for it.
Well, I know logically that both life and environment change over time. So I think the answer would be C, studying fossils shows us that both life and environments change over time. Hope this helps.
Answer:
A specialized cell means that even though they are similar, cells differ in size, shape or function depending on their role in our bodies. Each type of cell is modified to work in the way our bodies need it to. Specialized cell group together to form tissues.
