salamat sir sa reviewer..
ReplyDeletethanks sa reviewer sana po makapasa ako
ReplyDeletethank u po sa reviewer.. God Bless po :)
ReplyDeleteThank you for sharing this reviewer for it helped me a lot. There are some corrections though like for #36, the correct answer is A instead of D. The membrane that surrounds the lungs are called pleura, pericardium is the membrane that surrounds the heart.
ReplyDelete#35 ..no answer it should be phycoerythrin
ReplyDeletei agree
Deletegot 60 out of 100..hmmm i need more review.. thanks for sharing this..
ReplyDelete80/100 hahaha pwede na... mali mali ang mga answer keys
ReplyDeleteI HOPE THIS WOUL
ReplyDeleteD UPLIFT MY RETENTION SIR THANK YOU!!
74/100.Okay na yan, pero balak kong magtop heheh. Andami pong mali sa questions. Yung automatic, ok lang sana kung basehan ang meaning kaso mas mahusay kung autonomic yun.
ReplyDelete55 out of 100... kaya ko 'to, pag-iigihan ko pa. first year pa naman ako ee.. may 3 years pa for harvesing a lot of stuff.. :)
ReplyDelete#63 should be b. thrombocytes. irreguarly shaped cells without nuclei.
ReplyDeleteThe answer on the slowest velocity of blood flow should be CAPILLARIES, NOT VEINS!
ReplyDeleteveins is correct. remember highest pressure is from the heart beating during systole.
Delete35. Pharynx? Really. Are all answers even correct? I stopped checking my answers when I came across this. Some options of some questions aren't sensibly related to one another too, like no.2. Sad if some people passed LET without even noticing this. Poor children of the future.
ReplyDeleteAir, food and liquid all pass through this common passage, the oropharynx. The two passages separate again here, in the hypopharynx. Food and liquid pass backward into the esophagus on their way to the stomach. Air passes forward through the larynx and into the trachea, on its way to the lungs.
DeleteGuys eto pa po free let reviewers sa mga gusto :)
ReplyDeleteLATEST LET REVIEWERS COMPILATION
Kindly update your answer key please. If I had no prior knowledge to some of the questions that have wrong answers, I might think that it is really the right answer and answered it to the examination.
ReplyDelete36.What is the membrane that surrounds the lungs?
ReplyDeleteA. Pleura
B. Meninges
C. Peritoneum
D. Pericardium
The answer is letter A not C. Peritoneum belongs to our abdomen. Mali mali mga answers eh.
yes i agree to this one. .. sa number 36. the answer is pleura not pericardium because the pericardium is the serous membrane that covers the heart not for the lungs
Deletetext nyo na lang ako kung oorder kayo ng reviewers for major or for gen ed and prof ed. sa 0999-9401794. Pede rin pm me sa messenger ko sa fb ko: crisencio m. paner. I assure you very effective mga reviewers ko, napakarami ng nakapasa dahil dito. Da best din nyong gawin ay magpa let coaching sa akin, lalo na kung ilang beses ka ng bumabagsak sa let.
ReplyDeleteThe answer for #13 is A not C. It should be Spontaneous or CONTINUOUS.
