I heard of a possibilty from my Gr. 8 Science teacher: our eyes will grow larger, our noses will sink into our face as well as our ears, our teeth won't be as sharp, our pinkies and little toes will cease to exist and our lips not as distinguished. We may also have larger brains. I think it was a joke, since his description was close to that of the 'Little Green Men'. What do you guys think?

Explain Abstract:

Bcl-2 family proteins are potent regulators of programmed cell death. Although their intracellular localization to mitochondria and the endoplasmic reticulum has focused research on these organelles, how they function remains unknown. Two members of the Bcl-2 family, Bax and Bak, change intracellular location early in the promotion of apoptosis to concentrate in focal clusters at sites of mitochondrial division. Here we report that in healthy cells Bax or Bak is required for normal fusion of mitochondria into elongated tubules. Bax seems to induce mitochondrial fusion by activating assembly of the large GTPase Mfn2 and changing its ubmitochondrial distribution and membrane mobility—properties that correlate with different GTP-bound states of Mfn2. Our results show that Bax and Bak regulate mitochondrial dynamics in healthy cells and indicate that Bcl-2 family members may also regulate apoptosis through organelle morphogenesis machineries.

This question was on my exam today. I looked it up but still not sure. Oxygen is insoluble in water and plasma is made up of 90% water. Also fibrin is a substance converted from fibrinogen protein. If fibrinogen protein is in plasma, does this mean that fibrin protein is in blood plasma? The question on the exam asked what was NOT in plasma: oxygen, fibrin protein, antibody, or electrolyte?

2.)Achlorhydria is a condition in which the stomach stops producing hydrochloric acid and other secretions. What effect would achlorhydria have on the digestive process? On red blood cell count?3.)In carbon monoxide (CO)poisoning, CO binds to hemoglobin, preventing the uptake of oxygen by hemppglobin. When CO binds to hemoglobin, the oxygen-hemoglobin dissociation curve shifts to the left. What consquences of this shift on the ability of tissues to get oxygen? Explain.4.)You and your physiology instructor are trapped in an overturn ship. To escape, you must swim underwater a long distance. You tell your instructor it would be good to hyperventilate before making the escape attempt. Your instructor calmly replies, "what good would that do, since your pulmonary capillaries are already 100% saturated with oxygen?"what would you do and why?5.)Is the oxygen-hemoglobin dissociation curve in humans who live at high altitides to the left or right of a person who lives at low altitudes? Explain
