Answer:
Facilitated diffusion
Explanation:
Oxidative phosphorylation, involving the Electron transport chain and Chemiosmosis is the third stage of cellular respiration. The main purpose of the ETC is to build an electrochemical (electrical and concentration) gradient across the inner mitochondrial membrane. It does this by using energy to pump protons (H+ ions) from the matrix to the inter-membrane space of the mitochondria.
Facilitated diffusion, also known as passive transport through channels, is a form of facilitated transport involving a passive movement of molecules along their concentration gradient, through channels called membrane proteins.
During Chemiosmosis of Oxidative phosphorylation, protons (H+) flow back down their concentration gradient (from inter-membrane space to matrix) due to the chemiosmotic gradient that has been formed in ETC. However, hydrogen ions (H+) cannot pass through the inner mitochondrial membrane except through an enzyme (protein) found in the inner mitochondrial membrane called ATP synthase. This protein acts as a machine powered by the force of the H+ diffusing through it, down an electrochemical gradient. This movement of H+ via ATP synthase further catalyzes the conversion of ADP to ATP.
It is an example of facilitated diffusion because H+ ions are diffusing across the inner mitochondrial membrane (from inter-membrane space to matrix) via a protein channel or membrane protein called ATP synthase.
The movement of H+ through the ATP synthase is best described as an example of chemiosmosis, which involves the movement of ions across a membrane through a specialized protein channel to generate ATP.
The movement of H+ through the ATP synthase is best described as an example of chemiosmosis. Chemiosmosis is the movement of ions across a membrane down their electrochemical gradient through a specialized protein channel like the ATP synthase. This process generates ATP, the energy currency of the cell.

Answer:
Answered below
Explanation:
Birds and mammals have a double circulatory system and a four-chambered heart which separates the oxygenated blood and the deoxygenated blood from each other in the heart. This system of circulation is necessary to serve the high energy needs of the mammals and birds.
In this system, deoxygenated blood from the body passes through the superior and inferior Vena Cava into the right atrium. From the right atrium it flows into the right ventricle. From the right ventricle, it is then pumped into the pulmonary artery to be carried to the lungs. In the lungs, the deoxygenated blood is oxygenated and returned to the heart through the pulmonary veins.
Oxygenated blood enters the left atrium from the lungs through the pulmonary veins. It then moves into the left ventricle. In the left ventricle, it is then pumped into the aorta. The aorta is a large vessel that runs the length of the vertebral column, branching off to be circulate blood in the body system.
Answer:
The correct answer is minority influence.
Explanation:
According to the concept of minority influence, the smaller groups will affect the individuals on the basis of their opinions and perspectives on the topics, which are not witnessed by many. They develop a perception, which is not common and majorly are from their observations of the things, which are required to get better in the humanity and community.
The two factors would be "Temperature, and nearness to bodies of water".
The Northern Hemisphere is tilted toward the sun.
Locations in the Northern Hemisphere experience 12 hours of daylight and 12 hours of darkness.
Locations in the Southern Hemisphere experience long days and short nights
