The molecule will enter the cell using a channel protein.
Answer:
50%
Explanation:
Glucose is a simple sugar with a total of 6 carbon atoms in its structure. Pyruvate has a total of three carbon atoms. Two molecules of pyruvate are obtained per glucose by glycolysis. None of the carbon of glucose is released in the form of CO2 during glycolysis. Therefore, the radio-labeled C-1 of glucose will be the component of the carbon skeleton of one of the total of two pyruvate molecules produced during glycolysis. So, 50% of the pyruvate will exhibit radioactivity.
The answer to your question is option b
This is because if the trees are black, and covered with soot due to the pollution, caused by industrialisation, the white moths will be easily seen and constantly hunted by the predator, compared with the black moth population as they camouflage easily. Ultimately, the white moths would be hunted to such an extent that their population would dramatically decrease
