A. The electronB. The nucleusC. The neutronD. The proton 相关知识点: 试题来源: 解析 B. The nucleus 原子的中心被称为原子核。原子核由带正电的质子和不带电的中子组成,电子则在原子核周围运动。因此,正确答案是 B. The nucleus。反馈 收藏 ...
A proton is a subatomic particle found in the nucleus of atoms that differs from the other subatomic particles (called neutrons) in the nucleus of most atoms because each proton has a positive charge of +1 (as opposed to neutrons, which have no charge).

(d) Immunoblots of proteins located in nucleus (PARP1), ER (Calnexin), Golgi (GM130), mitochondria (NDUFS3), and cytoplasm (PSPH and tubulin) in cytosolic and organellar fractions. Cytochrome c is used as a control for intact organelles (mitochondria). Data are shown as mean ± s.d....
They onlyappearn labs.All elements have a similar structure. They have a nucleus. This is the element'score Inside the nucleus are protons and neutrons. Elements have differentnumbers ofthem. For example, hydrogen has 1 proton and 0 neutrons Heiumhas 2 protons and 2 neutrons Oxygen has 8 ...
