Answer:
a. The operon is under positive control
a.) Loss of enzyme synthesis results from loss of regulatory R gene product which is regulated in the presence of Tis ophane for transcription. Absence of (Tis), transcription is positively controlled by regulatory Rprotein
b.) The proposed model reveals Tis / B complex prevents Tis enzymes from undergoing transcription through the RB operator by binding to the B region
the role of the R protein is
-decrease affinity of Tis / B complex to B region of RB
-bind to the R region on RB
- change the conformation of B region
- yield decreased affinity of Tis / B complex when R gene is lacking preventing transcription in the process
Effects of the RB mutations is that R protein will not bind to Tis / B complex to reduce transcription
<h3><u>Answer;</u></h3>
Differences in heating
The flow of air caused by <u>differences in heating </u>and the Coriolis effect creates distinct wind patterns on Earth's surface.
<h3><u>Explanation</u>;</h3>
- <u>Movement of air or flow of air is caused by pressure or temperature differences and is experienced as wind.</u> When there is a pressure difference between two places, a pressure gradient exists, across which air moves from the region of high pressure to the region of low pressure.
- <em><u>Differences in temperature also causes movement of air or wind know as convection. The air flow caused by temperature difference is observed in the case of sea and land breezes, because of the difference in temperature between the sea and the land.</u></em>
Answer:
During the oxidation of glucose in the liver the malate aspartate shuttle system is used, therefore, two additional ATPs get generated at the step constituting glyceraldehyde-3-phosphate dehydrogenase.
On the other hand, in the brain, a cell uses the glycerol phosphate shuttle system, which generates two less number of ATPs. However, the remaining of the energetics for the number of ATP in both cases are similar.
Thus, the difference is based upon the kind of shuttle system used that leads to the production of 32 ATPs in liver cells and 30 ATPs in the brain cells.
B) Geothermal energy
It is heat within the earth
