To discuss:
Haptens and how they become antigenic.
Introduction:
For all living organisms, there is a challenge for surviving by defeating the entire pathogenic organism. The human body kills the pathogen or eliminates the foreign particles by an organized system called the lymphatic system. The lymphatic system or immune system consists of a group of cells or immune cells that inhabit all the organs of the body. The lymphatic system includes lymphatic organs and a group of lymphatic tissues that are involved in the immune system.
An antigen is any substance (molecule) that stimulates an immune response. Free molecules such as toxins, venom, and food substances act as antigens. Other antigens include components of bacterial cell wall and plasma membrane.

- explain the cascade of events (starting with relaxing trade winds) that occurs during El Niño in the eastern Pacific (off the coasts of California/North America and Peru/South America) and which lead to food-chain collapse - start with changes in the physical/oceanographic conditions, andthen systematically describe the cascading effects at each level of the food chain -arrow_forward3) Which statement(s) about the Pacific Decadal Oscillation (PDO) is/are TRUE? CIRCLE ALL THAT APPLY. A. It is a major driver of salmon populations in the Pacific B. It affects sea surface temperatures in the eastern Pacific C. Its cycles typically do not last as long as those of ENSO D. Evidence that it has occurred over many centuries has been gathered from tree ring dataarrow_forward4.arrow_forward

If you add heterotrophic respiration and autotrophic respiration together and then subtract that value from gross primary productivity, then you have a more refined estimate of ecosystem carbon storage than NEE. Differential heating due to the earth's tilt generates the global wind AND oceanic circulation patternsarrow_forward1arrow_forward
