[生物] 有關生物的問題
Asexual reproduction and sexual reproduction differ in all but
which of the following ways?
選項我提有問題的就好了
b)asexual reproduction produce offpring that are genetically identical to
their progeny, whereas sexual rproduction give rise to genetically distinc
offsprings
d)asexual repro requires only mitosis but sexual always involves meiosis
e)asex repro is utilized only by fungi and protists, whereas sex repro
is utilized by plants and animals
答案是e 可是我覺得b才是
而d是覺得有問題但是不知道出在哪
which of the following describe the events of apoptosis
B)it's dna and organelles become fragmented, it dies,and is phagocytized
d)it's dna and organelles are fragmented,the cell shrinks and forms blebs,
and the cell self-digest
答案是d
上面這題我記得是macrophage把細胞吃掉吧
為什麼是self-digest???
有一題也有問題不過用中文問好了
CO2用O18代替 答案說這個O最後會以O2釋出
但是02不是因為在光反應中是撕裂水所造成的
所以這個O應該是跑去葡萄糖或者是RUBP吧
還有一題是問呼吸作用在植物的什麼時和什麼地點發生
答案給在光合細胞是指有在DARK PERIOD但在其他組織是全天
這跟我在高中學的完全不一樣耶 想請教一下為什麼會這樣
一次問這麼多問題真的很抱歉 積太多了= =
禮拜五就要其中考了 希望大大可以幫幫小弟解惑
M(_ _)M 謝謝了

可是我看CAMPBELL上說The cell shrinks and becomes lobed (called "blebbing~)
and the cell's parts are packaged up in vesicles that are engulfed and digested by specialized
scavenger cells, leaving no trace
上面的scavenger cell我查google是巨噬cell...
