The first sound of heart, "lub" produced when
Atrioventricular valves open, semilunar valves open
Atrioventricular valves open, semilunar valves close
Atrioventricular valves close, semilunar valves open

During Atrial diastole & Ventricular systole phase, pressure between atria and ventricles?
Pressure in atria are greater than ventricles
Equal pressure in atria and ventricles
Pressure in ventricles are greater than atria
During Atrial & Ventricular diastole phase, what happen between vena cava, right atrium & right ventricles?
Pressure in vena cava is greater than in atrium and pressure in atrium is greater than ventricles, hence blood flow from vena cava into the right atrium and into the right ventricles by passive transport.
Pressure in vena cava is lower than in atrium and pressure in atrium is lower than ventricles, hence blood flow from vena cava into the right atrium and into the right ventricles by passive transport.
Pressure in vena cava is greater than in atrium and pressure in atrium is lower than ventricles, hence blood flow from vena cava into the right atrium and into the right ventricles by passive transport.
Pressure in vena cava is greater than in atrium and pressure in atrium is greater than ventricles, hence blood flow from vena cava into the right atrium and into the right ventricles by active transport.

Passive; energy
Active; ions
Passive;ions
What is the important of companion cell between source and sieve tube?
Provide glucose for active transport
Provide ATP for active transport
Provide ATP for passive transport
Provide glucose for passive transport
Loading of sucrose actively in the sieve tube will causes
Water pressure in sieve tube decrease
Accumulation of sucrose in sieve tube and water potential remain unchanged
Sucrose dissolved in water and lowered the water potential in sieve tube
Sucrose converted into dissolved glucose which lowered the water potential in sieve tube
