Yes. An udder cell was taken from one sheep and injected into an unfertilized cell. These were caused to fuse by the use of electrical pulses. Once fused, the cell was transplanted into a surrogate mother.
an isotope of the element helium is obtained.
Cells don't die after the nucleus is removed. That is how we clone things, we remove the nucleus from an unfertilised egg cell and insert the DNA of the animal we wish to clone.
No, a eukaryotic cell cannot survive without its nucleus. The nucleus contains the genetic material (DNA) and is responsible for controlling the cell's activities, including protein synthesis and regulation. Without the nucleus, the cell cannot reproduce or perform essential functions necessary for survival.
The force that must be overcome to remove an electron from an atom is the electrostatic attraction between the electron and the positively charged nucleus. This force is governed by Coulomb's law and is known as the ionization energy. The amount of energy required to remove an electron depends on the specific atom and its electron configuration.
Helium, number two on the periodic table of elements. Nothing else has two protons, for to remove a proton or add a proton is to change the element.
The amoeba dies
depends on how they did it. Did they remove your ovaries? If not your ovaries will produce more eggs. They can not remove all of them unless they remove your ovaries. Then you will no longer produce eggs.
Valence electrons are further away from the nucleus and experience less attraction to the positively charged protons in the nucleus compared to core electrons. This makes valence electrons easier to remove from an atom. Core electrons are located closer to the nucleus and are more strongly attracted to the nucleus, requiring more energy to remove them from the atom.
What?
The lamb will look like Harry because it has his genetic information (the nucleus taken from Harry) planted inside it. It will not look like Sally because her nucleus has been removed and so it no longer contains any genetic information to do with her.
an isotope of the element helium is obtained.
Yes
It would be more difficult to remove an electron from bromine than from sodium because bromine's valence electron is farther from the nucleus, experiencing weaker attraction compared to sodium's valence electron, which is closer to the nucleus.
Think of it as like trying to lift a heavy stone up out of a conical pit. The nucleus is down at the bottom of the pit. It takes more work (energy) to remove the stones (electrons) that are deeper in the pit (closer to the nucleus). Remember that the lower numbered shells are lower (deeper) in the pit, and you won't go wrong.
The energy required to remove an electron from a gaseous atom is called the ionization energy. This energy depends on factors such as the atomic structure and the strength of the attraction between the nucleus and the electron. The higher the attraction, the higher the ionization energy needed to remove the electron.
Cells don't die after the nucleus is removed. That is how we clone things, we remove the nucleus from an unfertilised egg cell and insert the DNA of the animal we wish to clone.
Cloning is creating an exact genetic copy of something. To clone first take the nucleus from a donor cell, and collect some unfertilized eggs. Remove and replace an egg nucleus with the donor cell nucleus, and put the egg in a womb, for it to be born.
