Chemical composition is always a property of an ore.
Answer:
A proton gradient is generated by the transport of protons into the thylakoid lumen.
Protons move from the thylakoid lumen to the stroma through ATP synthase, producing ATP.
Explanation:
During photosynthesis, the environment is made acidic inside the lumen i.e. H⁺ are pumped into thylakoid lumen from stroma as a result of which more H⁺ are present in the thylakoid lumen as compared to stroma. It happens during light dependent reaction of photosynthesis. The concentration of H⁺ is already higher in lumen and transfer of more and more H⁺ from stroma increases the concentration of H⁺ even more leading to generation of a potential gradient. These H⁺ subsequently tend to move freely from lumen to stroma via "reverse pumps known as ATP synthase". The reason why these are known as reverse pumps is because pumps usually move particles from lower to higher concentration which is an active movement i.e. not natural so such movement requires energy. Naturally particles move from higher to lower concentration gradient until the concentration becomes equal on both the sides but pumps act opposite of this natural process and move particles from lower to higher concentration and utilize energy to do it. But here H⁺ are moving from higher to lower concentration which occurs naturally so ATP synthase rather than using energy tend to generate energy and this free energy is used to generate ATP from ADP & Pi (inorganic phosphate).
The option that is an example of the "ethical dilemma" of creating and destroying human embryos is option A: Some people..."believe an embryo has the same moral standing as a human being?"
<h3>What moral dilemmas do embryonic stem cells present?</h3>
The infinite differentiation potential of iPSCs, which can be used for human cloning and pose a risk for the creation of human embryos and human-animal chimeras, is the center of the current ethical debates surrounding stem cell-based therapies.
However, due to the fact that it involves the killing of human embryos, hESC research is morally and politically contentious. The controversy over abortion has a strong connection to the issue of when human existence begins in the United States.

Answer:
Adolescent
Explanation:
Globally about 50% of mental health issues and conditions start at the age of 14. Most of them are not detected and treated. One of the most common causes of mental issues is depression among adolescents. The common factors leading to mental distress among adolescents include exploration of sexual identity, exposure to different social behaviours, money and access to technology.
