why is it important for signal conduction in heart to stop for a while in AV node?
to prevent atrium and ventricle from contracting at the same time
to prevent blood too much flowing from atrium to ventricle
to make sure that all valves are open before blood sent out from heart
to make sure there is enough time for atrium to receive blood from veins

Which of the statement is true?
sinks: places where sugar is made
sinks: places where water is made
sinks: places where sugar is delivered to
sinks: places where water is delivered to
The loading of sucrose into sieve tubes is by ________ transport and consequently, requires ___________.
Active; ATP
Passive; energy
Active; ions
Passive;ions
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
Which one is NOT the effect causes by loading of sucrose into sieve tube?
Increase water potential in sieve tube
Decrease the water potential in sieve tube
Water potential in sieve tube is lower than xylem
Water diffuse from xylem into sieve tube by osmosis
What is the best words to describe sugar source and sugar sink
Both are plants organ and act as storage
Sugar sink can be either roots, fruit or mature leaves and sugar source is shoots
Sugar source act as site for sugar production and sugar sink will store sugar
Companion tube carry food from a sugar source to a sugar sink
The mass flow theory is best defined as the idea that
sucrose is transported due to a negative pressure in a source
large volumes of solution are transported from an area of high hydrostatic pressure
water travels from a high to low concentration
sucrose diffuses to all cells equally
Choose the correct order of the chambers through which deoxygenated blood flows in the human heart.
right atrium-----> right ventricle------> aorta
right atrium -----> right ventricle------> pulmonary artery
left atrium------> left ventricle------> aorta
left atrium-------> left ventricle-------> pulmonary artery
The basic transpiration-cohesion-tension mechanism involves..
The entrance of water and ion actively through cell membrane of the root epidermis.
Water flows in, generating positive pressure
The formation of weak bonds between water molecules and between water molecules and vessel walls.
The movement of water into root tissue through stem xylem and leaf xylem, then to the atmosphere

Root pressure which plays a small role in xylem flow is caused by
transpiration of water out of the xylem.
