Uranium-235 is the answer
There are some reasons which could be mentioned:
1)Energy is lost as heat at each feeding level
2)Consumers who feed directly on plants have more energy for themselves than consumers feeding on other consumers. Indeed, energy again is lost in each level.
3)Feeding cattle is not productive, because energy must be transferred from plants to the cattle and then to people.
Answer:
Island finches did not have beaks of the same size and shape
Explanation:
This is the evidence of variation, and therefore proof that the finches were able to survive the selective pressure by adapting their beaks to different feeds. Therefore finches that were able to adapt adjusted their beak shapes to the selecting pressure 'feeds' in the environment, and are naturally selected, and therefore adapted and evolved with time .While those without the surviving beaks lost out.
Thus changes in selection pressure, necessitated corresponding change in the beaks shape for adaption to survive( due to variation, ) and therefore natural selection for evolution
Answer:
The correct answer will be option- Glycolysis.
Explanation:
Gluconeogenesis is a metabolic pathway which synthesizes glucose from non-sugar precursors. This pathway is activated in the low concentration of glucose due to less intake or completely absent to conserve energy.
This pathway is somewhat the reverse of the glycolysis when excess energy is present as a result of glycolysis, gluconeogenesis is inhibited and when no energy is present, gluconeogenesis is activated.
Thus, option- glycolysis is the correct answer.
