The specialized lymph capillaries located in the small intestine? An antigen in any substance that the body regards as foreign. Lymphocytes are specialized red blood cells that attack specific microorganisms. B cell are most effective against viruses and bacteria that are circulating in the blood.
Answer:
All organisms depend on the production of energy, in order to function. Most of them make use of glucose as the main material for extracting the necessary energy to survive. However, some of these organisms will use, or not need to use, oxygen, in conjunction with glucose, in order to be able to generte ATP, the molecule that is responsible for powering up a living organisms´ cellular activities. In order to achieve this formation of ATP, then, all organisms will need at least glucose present, and most, will require also the presence of oxygen, to generate ATP. The two mechanisms by which ATP is produced, then, are: aerobic and anaerobic respiration.
In similarities, these two processes have several. First, the two require a substrate to work with, which is glucose, or a source that can yield glucose molecules. The second is that both mechanisms are used to provide ATP to living organisms, and three, they both are ways to acquire energy.
However, there are also differences. The most important being that aerobic respiration requires not just glucose, but also oxygen, in order to produce ATP, while anaerobic respiration just needs glucose. The second most important is that anaerobic respiration yields much less ATP molecules than aerobic respiration. And the third difference is that while from the chemical reaction in aerobic respiration an organism gets water and carbon dioxide, the second reaction in anaerobic respiration yields lactic acid and also ethanol (fermentation).
Answer:
1. George O’Malley (Season 5, Episode 24)
The world collectively gasped when George was revealed to be on the other side of the elevator doors, dressed in his Army uniform, ready to guide Izzie (Katherine Heigl) to the afterlife. This intense Season 5 ending was the audience’s first time witnessing the death of a main circle doctor, forever raising the stakes to come. From Callie recognizing the freckle, to John Doe tracing “007” into Meredith’s palm, each moment created goosebumps. The underdog of the interns didn’t deserve to go out being dragged under a bus, but it’s only fitting that he did it to save someone else’s life.
2. Denny Duquette (Season 2, Episode 27)
Love makes people do crazy things; but, unfortunately cutting L-Vad wires, breaking the law, and Izzie almost losing her job couldn’t save Denny Duquette from death. Isabel and Denny’s love story was the first flame that could’ve shone brighter than Meredith and Derek’s. It’s largely why the death of Denny was so heartbreakingly tragic. Although Izzie seemed to move on, Denny’s ghostly cameo in Season 5 made it clear the love story was always doomed.
