Question

Give reasons
Ventricles have thicker walls than atria
Transport system in plants is slow
Circulation in aquatic organism differs from that of terrestrial
Veins have valves Altria’s do not
During day time water travells in plants faster than during the night time

Answer 1

Explanation:

ventricle pump blood so they have thicker walls

as plants have only xylem and phloem they have slow transport system

to prevent backflow of boold veins have valves while arteries don't

as photosynthesis process takes place in day the and the co2 is given out in night the process of taking water takes place faster in night
