Both options are valid because they have happened before and can influence the mentioned drop in the population. Toxins in the food chain, just like the increase of water temperature, are easily proven and found and are mostly human made.
False we are made out of A lot of different Troyes of cells
Answer:
A proton Pump, using ATP, pumps protons outside
A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.
pH decreases;
The gradient becomes sufficient.
H+ moves down electrochemical gradient into the cell; Sucrose moves into the cell.
Explanation:
A proton Pump, using the energy of ATP hydrolysis, pumps protons outside the cell.
A steady proton gradient with a higher concentration of H+ out of the cell is maintained by the proton pump.
The continues outward pumping of protons by the proton pump causes the pH of the extracellular fluid to decrease
At some point the gradient becomes sufficient, and pH reaches a steady slightly acidic level.
H+ moves down its electrochemical gradient into the cell together with Sucrose through the hydrogen ion-sucrose co-transporter.
Bats and birds are unrelated animals, yet they both evolved wings. by acquiring similar traits (i.e., wings) as they adapted to similar environments, these species exhibit convergent evolution through analogy present between the wings. Convergent evolution happens when two distantly related organisms acquire the similar traits in response to the similar habitat or niche.
The difference between a monogenic inheritance and a polygenic inheritance are the amount of alleles they depend on. A monogenic inheritance depends on only one single allele while a polygenic inheritance depends on multiple alleles. Monogenic refers to qualitative traits and polygenic refers to quantitative traits.
