One example of a common day Saurischia, or more accurately a currently living direct descendent of this group, is the chicken.
As far as the Saurischia go, they represent a large group of dinosaur species. The fact is that long ago, <em><u>all non-avian members of this group went </u></em><em><u>extinct</u></em><em><u>.</u></em> The remaining members were avians, a word currently associated with birds. This in part provides an explanation for the fact that most of these remaining Saurischia later evolved into many of the common-day birds we see in the modern world.
Therefore, to give the most popular and clear example of what we can consider as a <u>member of the </u><u>Saurischia</u><u> that is still alive today</u>, we can use the common chicken. The chicken is a direct descendent of the dinosaurs and is <u>the animal that genetically is the closest in relation to </u><u>dinosaurs</u><u>. </u>

Answer:
cleavage of MIC at the cell surface by a protease
Explanation:
The immune system refers to a complex network of cells and proteins that function to eliminate potentially tumorigenic cells on a daily basis. However, cancer cells show mechanisms in order to escape immune responses. MHC class I chain-related proteins A and B (MICA and MICB) are expressed in normal and tumorigenic cells where they act as ligands of the NKG2D receptor. The expression level of these proteins (MICA and MICB) is finely regulated by the activity of metalloproteinases (i.e., by protease-mediated cleavage), but this mechanism is altered in cancer cells. Recently, drug therapies that stimulate NKG2D mediated tumor destruction by reducing the cleavage of MICA and MICB from the surface of cancer cells have been developed.
<span>7. Extra sugar into the blood to provide enough food source. It can also trigger the hormone adrenaline which gives energy.
8. Bone marrow increases the white blood cell count which overall increases the chance of countering infections
9. The parasympathetic nervous system is responsible for keeping the body at a relaxed state . I.e. it would reduce the heart rate if it is too high. The parasympathetic nervous system is affected by a stresser causing it to become inactive until the stressor has gone
10. increased blood pressure can develop into chronic stress.
11.If you have chronic stress lasting more than a month there is a high probability you will catch an infection.
12. Our sympathetic nervous system controls stress by changing our body state i.e. higher heart rate.
13. Renin is an enzyme that is secreted into the body by the liver which is used to restore liver stress levels.
14. Glucocorticoids is a series of hormones/drugs that are used to treat any inflammatory conditions especially in the brain, liver and kidney
15. The immune system is made up of more than a trillion white blood cells all coded to help deal with different types of pathogens.
16. Its a type of hormone produced by the thymus gland which is heavily used in the immune response to fight off infections.
17.a large cell that is found in the damaged tissue which helps fight off infection
18. It is a type of lymphocyte responsible for the production of antibodies. it can be found all over the body
