The saphenous veins -- there are two, the great and the small saphenous veins - serve as the principal veins running superficially (near the surface) up the leg.
The great saphenous vein (also called the large saphenous vein) goes from the foot all the way up to the saphenous opening, an oval aperture in the broad fascia of the thigh, a fibrous membrane through which the vein passes.
The small saphenous vein runs behind the outer malleolus (the protuberance on the outside of the ankle joint), comes up the back of the leg and joins the popliteal vein in the space behind the knee (the popliteal space).
The enzyme that is present within the stomach and the lining of the muscular gland, would function optimally in high H+ concentration and would require much HCl needed for an appropriate pH environment to function
This would be pepsin, I believe.
Answer:
b. Many mitochondrial proteins are coded by cellular nuclear DNA.
Explanation:
According to the concept of endosymbiosis, eukaryotic organelles such as mitochondria and chloroplasts arose from symbiotic relationships between larger cells and smaller prokaryotes. These smaller prokaryotes were incorporated and lived within them. According to this concept, mitochondria originated when a larger cell engulfed an aerobic bacteria (most probably the purple bacteria) that lived in it. However, some of the proteins of the mitochondria are encoded by nuclear chromosomes. This dependence of mitochondria on nuclear DNA does not support the concept of endosymbiosis.
Some species cell division produces reproductive cells in sexually reproduce organisms
Answer:
its a tuberculosis because they are acid fast
what it means is that high concentration of acid doesn't make them loose dye and they are still viable and able to retain dye that we added before acid so it appears to us as red or pink
