Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground.
Answer:
Explanation:
1- the purpose of blood flow-circulatory system- is to convey Oxygenated blood, oxygen bonded with haemoglobin in the RBC with Nutrients - and distributed these through the arteries and capillaries away from the heart, to reach the cells and tissues, and transported the wastes of theses cells and tissues , with C02 through the veins back to the heart and the kidney.
2. During diastole,deoxygented blood from the inferior and superior vena cavae entering the R.atrium, passes through the tricuspid valve into the Right Ventricle. Simultaneously, oxygenated blood returning through the pulmonary veins enters the left Atrium,emptied through the bicuspid valve into the Left.Ventricle.
During systole, the two ventricles contracts. The Right ventricle contracts, the pressure of the blood forces the tricuspid valve to close,and therefore de -oxygenated blood pushes the pulmonary valves to open and blood passes through the pulmonary artery to reach the lungs where exchanges of oxygen with carbon dioxide occurs.The blood is now oxygenated and returns to the left atrium via pulmonary veins.
Simultaneously, the left ventricle contracts,the oxygenated blood it contains forced the bicuspid valve to close so that blood is forced through the aortic valve to empty into the aorta into the systemic circulation,branches of the carotid artery supplies the heart from the aorta.
The Whole cycle continues.

Bariatric surgery works to establish a new set-point by altering body weight and establishing weight loss results.</span>
Answer:
The correct answer is option A, that is, cotransport proteins.
Explanation:
The variable that possesses the tendency to mediate energy based on chemical potential is termed as an electrochemical gradient. The electrochemical gradient is differentiated into two parts, that is, electrical gradient and chemical gradient. Both these forms of gradient take place over the surface of a membrane.
The movement of the majority of the ions takes place by the phenomenon of electrochemical gradients, of which some are found on the surface of the membrane and function as electrogenic pumps. While the gradients of some of the ions are mostly accounted for by the co-transport proteins, as these proteins take part in the movement of ions or molecules through a plasma membrane that involves concentration gradient based on the kind of molecules and movement.
