I'm not sure if I will answer the question you asked, as I many have interpreted it incorrectly. In natural selection, there must be variance in the gene pool, the total frequency of alleles in a population. Now, one of the organisms may have a gene that somehow helps them survive from the selective force much better compared to the others. If this does happen, over time the gene pool will narrow down to become just the genes of that organism that survived better in the first place because the rest would be taken care of by the selective force. So, the alleles and trait come from the first organisms that had the advantage over the others of its species.
Answer: In animal and human studies, allulose has been found to lower blood sugar levels, increase insulin sensitivity and help protect the insulin-producing pancreatic beta cells.
H is grana, i is ATP, J is Calvin cycle, A is sugar, e is electron transport chain, c is Krebs cycle,
Answer: increases water permeability in certain portions of the kidney tubules.
Explanation:
The proximal convoluted tubule is the site in nephron where selective reabsorption of water and electrolytes like sodium and potassium ions occurs. From there water and other substances are reabsorbed and reenter into the circulation. This cause an increase in blood pressure and blood volume. Only the cells of the proximal convoluted tubule are permeable for this reabsorption process and they are stimulated by a hormone named as aldosterone.
