Answer:
i think its something to do with circle of life or stages of growth
Explanation:
<span>DNA exists in a coiled form in order for it to take up a smaller volume in the cell so that is why the first thing is that it needs to be unwound by topoisomerase. Then each piece is made up of two strands that must be separated as they need to be copied separately, so next the helicase unzips the DNA. DNA polymerase needs to have something to build off so because DNA can be synthesized, the Primase needs to make an RNA "primer". DNA is then synthesized but because it cannot synthesize the whole chromosome in one piece, after DNA synthesis, the ligase must glue the shorter pieces together to make the entire chromosome.
Correct Order
1. Topoisomerase unwinds the coiled DNA
2. Helicase unzips DNA to separate strands
3. Primase lays down short RNA strands
4. Polymerase synthesizes new DNA strands
5. The new strands are glued using ligase</span>
Answer:
The oxygen dissociation curve represents the percentage saturation of Hb with oxygen at different partial pressure of oxygen. The different partial pressures gives sigmoid shapes to the curve. When this curves shifts to right, it indicates low affinity or binding of oxygen by the Hb. it also indicates the unloading or releases of Oxygen by Hb molecules at condition of low pressure. e,g in the muscles during strenuous exercise.However, when the curve shifts to the left, this indicate high affinity for oxygen, great binding, at high partial pressure of oxygen.e,g in the lungs to take oxygen and releases CO2.
Therefore in this scenario, the statement -. <u>During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right.</u> is correct. because oxygen is needed by the muscles therefore ,oxygen should be less binded by Hb, decrease affinity and easily unloaded to muscles.
<u>The statement </u>This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 into hemoglobin in the lungs is wrong.
As explained above the rightwards shift indicated low affinity of Hb for oxygen(unloading)and favours unloading at the muscles because during strenuous exercise the partial pressure of oxygen is very low(but that of CO2 high) in the muscles which favours low oxygen molecules binding by Hb, and easy release to respiring cells.
Explanation:
That is false. Ecology is the study of relations of organisms to one another and to their physical surroundings. Cell biology is the study of cells and their functions.
Answer:
The correct answer is - acidic conditions wouldn't trigger a change in the color of Alizarin yellow.
Explanation:
The growth of E. coli generally occurs at neutral pH, however, its growth is normal at acidic conditions as well. The change in the growth of E. coli is not able to detect by alizarin.
The phenol red turns yellow in the presence of an acid, and the change in pH in an alkaline environment can be detected by the red color of phenol red. Growth of E.coli will grow in pH of 10-12 . But, very slowly. The color change in alizarin is also apparent at pH 10.2 to 12 only.
