因為arteriole 太高pressure, tissue fluid只可以向lymph vessel 流?

Give examples and explain the importance of negative and positive feedback mechanisms in the human body. (我估)

想問下鼓膜到底屬於外耳定中耳?
2018-04-05 19:46:35
生仔係positive feedback
control blood glucose level係negative feedback
Importance... 諗唔到
應該有2分既

你個腦壞左呀

使乜諗到咁難
純粹因為lymh vessel係個開窿既structure
跟住你有壓力禁到tissue fluid就會將d tissue fluid禁左入去
而d水既壓力就係叫hydrostatic pressure

屬於分隔外中耳既地方

positive feedback out of syllabus估乜春
2018-04-05 20:03:36
唔會咁問,因為佢係隔開外耳同中耳
2018-04-05 20:03:37
希望你係假膠
因為有讀過bio既人應該唔會講咁既野

more raw material for photosynthesis
CO2係high conc就唔會係limiting factor

搵唔翻點解係RNA 既解答 有冇人願意話翻比我知
2018-04-05 20:09:00
oh sor
我諗應該差唔多
2018-04-05 20:10:07
因為mRNA做完translation就會breakdown左 所以係short lived
我記得大概好似係咁

樓主係咪中大醫科生

因為DNA Stable d?
