Answer:
B
Explanation:
This H+ ion gradient is referred to as a proton motive force. It is created using energy from the Krebs cycle in the matrix of the mitochondria. As electrons are passed from one protein complex to another, reducing molecules such as NADH and FADH2, the protons are pumped to the intermembrane space of the mitochondria. ATP synthase uses this potential to generate ATP as the H+ ions move downgradient (back to the matrix) through channels in the protein enzyme.
<span>The correct answer for this question is A - Scientists ask testable questions and devise ways in which they can answer those questions through experimentation or observation. The rest of the possible answers for this question only describe some scientists.</span>
Answer:
question 1:
- both the number of species and population density decreases as altitude above sea level increases
question 2:
increase in birth rate => greater number of young organisms
Explanation:
As altitude above sea level increases, O2 density decreases, the amount of UV rays increases and the difference between daytime and nighttime temperature increases
I think this is True.
Hope this helps!
The Calvin cycle of photosynthesis starts when the energy of light is processed to chemical energy within the cells of plants. The ATP molecules created power the Calvin cycle. The Calvin cycle utilizes energy to create carbohydrates from h20 and co2.
