Answer:
E. They decrease the rate at which Ras hydrolyzes GTP.
Explanation:
Activated Ras has GTP bound to it, this propagates an intracellular signal to the nucleus where cell proliferation is induced. Thereafter proliferation is switched off by the hydrolysis of the bound GTP to GDP.
Therefore decreasing the rate of GTP hydrolysis causes Ras to remain active, ultimately leading to uncontrollable proliferation characteristic of cancer.
Zooflagellate is a free living protozoan with a whip like appendage. It is non-photosynthetic and feed on decaying organic matter. Euglena is a single cell flagellate eurkaryote, which has features of both plant and animal. Two organelles that are present in euglena but which are not present in zooflagellate are chloroplast and photoreceptors.
Answer:
The correct answer is - 19 ATP.
Explanation:
One molecule of dihydroxyacetone phosphate fully oxidizes and generate 19 molecules of ATP by the following stochiometry
Direct ATP- 2
ATP from NADH ( 5X3)= 15
ATP from GTP 1
ATP from FADH2 1 or 1.5
Total 19 or 19.5
Answer:
G=21 %
T= 29 %
A= 29 %
Explanation:
Since C only binds to G, you have the same amount of C and G, so G is 21 %.
100 % minus 42 % ( 21 % C plus 21 % G=) equals 58 %.
So the other 58 % is made of T and A. Since T only binds to A , the half of the extra 58 % is T and the other half is A. Therefore 29 % is T and 29 % is A
The stem of the plant should be cut at least three to four inches above the surface level.
The glass capillary should be tightly fixed with the stem.
The initial water level and the final water level should be carefully noted.
The droplets on the leaves should be observed and conclude that these drops are not from transpiration.
