<span>a. What is one adaptation of a mangrove tree species that allows it to survive in its environment?
Answer: </span><span>Two key </span>variations they need are the flexibility<span> to survive in </span>wet<span> and </span>hypoxia<span> (no oxygen) soil, </span>and therefore the<span> ability to tolerate </span>briny<span> waters. Some mangroves </span>take away<span> salt from </span>briny water<span> waters through ultra-filtration in their roots.</span>
Finches recognise individuals of their species based on appearance and songs. More specifically, finches differences in appearance that they can recognise include the body colour, size and shape. Concerning the songs that they sing, they are significant differences between the song that each species sing.
On my work the answer was D ..
Answer:
- Hydrogen ion concentration is lower in the mitochondrial matrix than in the intermembrane space.
- Oxidative phosphorylation relies on the hydrogen ion concentration gradient generated and maintained by the electron transport chain.
- Hydrogen ions enter the mitochondrial matrix via facilitated diffusion.
Explanation:
Oxidative phosphorylation is a metabolic pathway by which Adenosine Triphosphate (ATP) molecules are produced through the transfer of electrons from NADH or FADH2 to molecular oxygen (O2). The hydrogen (H+) ions are pumped from the mitochondrial matrix to the intermembrane space, and this movement of protons generates an electrochemical gradient across the mitochondrial membrane which is used by the ATP synthase to produce ATP. This gradient is generated by the movement of electrons through a series of electron carriers (e.g., cytochrome c and ubiquinone) that are embedded in the inner mitochondrial membrane. The movement of these H+ ions across the semipermeable mitochondrial membrane moving down their electrochemical gradient is named chemiosmosis and is an example of facilitated diffusion.
