<h3><u>Answer;</u></h3>
D) frequently, and sometimes rapidly
<h3><u>Explanation;</u></h3>
- The hypothesis that the Grants have been testing was about the natural selection shaping the beaks of different bird populations.
- <em><u>The Grants documented that natural selection takes place in the wild finch population frequently, and sometimes rapidly.
</u></em>
- The Grants' work showed that variation within a species increases the likelihood of the species' adapting to and surviving environmental change.
This is B; false.
Europe is not located in the tropics. In fact, no European countries lie in the tropical region. Europe is located in the temperate climate zone.
Answer:
ATP and NADPH
Explanation:
The photosynthetic process carried out by plants involves two distinct stages: the light-dependent stage and the Light-independent stage. The light-dependent stage occurs in the thylakoid membrane of the CHLOROPLAST and it involves a series of chemical reactions that results in the formation of an energy storage molecule (ATP) and reduced electron carrier (NADPH).
These molecules enters the Calvin cycle or light-independent stage. The chemical energy of ATP and reducing ability of NADPH are used to phosphorylate and reduce a 3-carbon compound (PGA) in the Calvin cycle. These two molecules (NADPH and ATP) are important to keep the Calvin cycle in place. Hence, the Calvin cycle is dependent on the light reaction and this two molecules link the two stages.
