cobra

眼镜蛇；（澳）头颅英释中释na poisonous African or Asian snake that can spread the skin of its neck to make itself look bigger

1 cobra venom,眼镜蛇毒

1 A set of changes in the mongoose’s receptor makes it resemble the cobra’s own resistant receptor..猫鼬受体的一系列变化使得它们类似于眼镜蛇自己的抗毒液性受体。

2 Sometimes an attacking mongoose is bitten, but it has another line of defense against the venom — its acetylcholine receptor has also evolved so that the cobra neurotoxin cannot bind to it..有时猫鼬也会被咬到，但它还有除了反应之外的第二种防御毒液的方式——它的乙酰胆碱受体同样进化到了不怕眼镜蛇神经毒素的地步。

3 However, when cornered, these snakes will raise their heads, sometimes with a third of their body off the ground, spread their cobra-like neck-flap, open their black mouths and hiss..但是，当被逼到角落时，这些蛇就会抬起头部，有时会有三分之一脱离地面，舒展开它们眼镜蛇般的脖颈，打开黑色的嘴发出嘶嘶的声音。
