Answer:
C. Coupled reactions establish an electrochemical gradient across a membrane.
Explanation:
- During cellular respiration in mitochondria, and during photosynthesis in chloroplasts, the electron transport chain requires a proton gradient to pump protons across the membrane by active transport.
- Protons flow back across the membrane by facilitated diffusion through ATP synthase, which utilizes them to phosphorylate ADP to ATP.
- This process of ATP synthesis by harnessing the elctrochemicaal gradient geenrated by the diffusion of protons across the biological membrane through ATP synthase is called chemiosmosis.
Answer:
The nasal cavity and its mucous have two primary purposes in the process of breathing: Role as a Passage for Inhaled Air: During inhalation, air enters through the nostrils and passes via the nasal cavity into the pharynx and larynx, the next sections in the respiratory tract, to eventually reach the lungs.
Explanation:
Hippos likely evolved from a group of anthracotheres about 15 million years ago, the first whales evolved over 50 million years ago, and the ancestor of both these groups was terrestrial. These first whales, such as Pakicetus, were typical land animals. They had long skulls and large carnivorous teeth. Hope I’ve helped ;)
