Read questions carefully.guys any last minutes tips plz
Answer is D right?
Thanks27:
waterlogged soil -> lack of oxygen -> aerobic respiration decrease -> less ATP is synthesis -> less ions is actively transport into the the root hair cell -> root pressure decrease
30: D because the blood is moving from the left atrium(LA) to the right atrium(RA), the volume of blood of RA increase. Since pulmonary artery is connected to RA, so the blood pressure in pulmonary artery increase (more volume of blood in RA). On the other hand, LA has less volume of blood, so the blood pressure in aorta decrease. The blood originally from the LA is oxygenated blood. So the % oxygenation of blood in pulmonary artery will increase (as oxygenated blood flows from LA to RA to pulmonary artery)
according to the question, it says the blood usually moves from LA to RAThanks
But for q30 whY can't we say that blood will move from RA to LA and every thing is the other way around?
