明了 唔該哂

呢兩日都係，學校老師叫我地呢兩日溫翻哂啲let leaning. 但溫完都好似好唔實在錦
淆底一個點

淆底一個點好，搵日去睇下先
諗住留番一份做當最尾溫多次書
dse用inspiratory centre同expiratory centre嘅inhibitory response去解釋breathing action係咪唔得
lm
e1?
epithelial cell?
55
我剩係記左respiratory center nervous output點影響respiratory muscles
同埋chemoreceptor點樣刺激respiratory center
你講嗰啲未聽過

同女朋友床上學bio
我想試下答,睇下有幾多分
1. Deletion at position will lead to a shift in nucleotide upstream;
which leads to a change in mRNA transcribed, the amino acids sequence translated will also be entirely different (i.e. AAG, TGC, GGC..). Production of enzyme I will be impaired as different protein folding lead to significant conformation changes and generation of malfunction proteins.
2. Only the amino acid sequence encoded at nucleotide position 4-6 will differ,
the remaining parts of the nucleotide sequence remains intact;
which will not lead to a significant difference in the entire protein structure.
Hence, the conformation and major enzyme function can be retained.

Can be mitosis/meiosis
想問下 即使條tendon斷咗 muscle係咪都依然可以contract
tendon只係transmit pulling force
muscle contraction係nerve control令到myosin+actin郁 (out-syl)

關我撚事呀 我地呢到個個都同考評局上床學bio呀
