Answer: exosphere
Explanation: Exosphere. This is the outermost layer of the atmosphere. It extends from the top of the thermosphere to 6,200 miles (10,000 km ) above the earth. In this layer, atoms and molecules escape into space and satellites orbit the earth.
Chinese hamster ovary cell production of recombinant tissue‐type plasminogen activator (t‐PA) was increased by amplification of cotransfected dihydrofolate reeducates cDNA using stepwise adaptation to increasing methotrexate (MTX) concentrations. The highest producing clones were isolated at 5 μM MTX and yielded 26,000 U/106 cells/day t‐PA (43 μg/106 cells/day). Above 25 μM MTX, cell specific t‐PA production rates became increasingly variable and the cDNA copynumbers decreased. No apparent correlation between the cell specific t‐PA production rate and the growth rate was observed upon sub cloning of the amplified cells. When MTX selection was removed, the t‐PA production rate decreased up to tenfold within 40 days; this was accompanied by an up to 60% drop in cDNA copynumber. Subclones isolated after 108 days of culture in the absence of MTX were, on average, sixfold more stable than their parental cells. In culture without MTX, the maximum stable t‐PA production rate obtained (over 250 days) was 7000 ± 750 U/106cells/day (∼12 μg/106 cells/day), approximately threefold lower than the maximum unstable levels of production reached under selective pressure. Taken together, these results define a wide range of the highest t‐PA expression rates obtained under MTX selection, for which stable expression without selection has not been reported
<h2>G
lycolysis</h2>
Explanation:
(a) glycolysis is Right Answer.
- Through <em>respiration</em> the cell takes <em>energy from oxygen and glucose, </em>making <em>water and carbon dioxide all the while.</em> <em>Carbon dioxide, then again, is a waste item, and leaves the body through the lungs</em>.
- At the point when you inhale out, you're really removing carbon dioxide.
- Cellular respiration utilizes energy in glucose to make ATP.
- High-impact ("oxygen-utilizing") breath happens in <em>three phases such as glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is part into two atoms of pyruvate. </em>
- <em>It is a first metabolic pathway of respiration to produce energy and.it make the ATP.the pyruvate</em>
