The nucleus in a cell is the membrane-bound organelle that contains the DNA for the cell. All eukaryotic cells have a nucleus, while the other cell...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your ...
Transfection is a powerful tool for biological research, and 3D cell culture plays an important role in its advancement. Learn what transfection is, its connection to 3D cell culture, and the innovate strategies for 3D transfection.
Protons have a positive (+1) charge, which balances the negative (-1) charge of the electrons that surround the nuclei of atoms. Protons have a relative mass of 1, which is the same as the relative mass of neutrons. The number of protons in an atom is called the 'Atomic Number' of...
What Is a Cell? Trees in a forest, fish in a river, horseflies on a farm, lemurs in the jungle, reeds in a pond, worms in the soil — all these plants and animals are made of the building blocks we callcells. Like these examples, many living things consist of vast numbers of cel...
‘the bramley is large and green, used mainly for cooking and is quite sharp tasting, while the granny smith is still green but normally much smaller and sweeter'. but these are all adjectives or attributes. what is actually different is the physical makeup of the cell nuclei. "and so ...
The human body is mostly water. Water molecules (H2O) contain hydrogen nuclei (protons), which become aligned in a magnetic field. An MRI scanner applies a very strong magnetic field (about 0.2 to 3 teslas, or roughly a thousand times the strength of a typical fridge magnet), which aligns...
Nuclear fission occurs when a heavy nucleus splits into lighter ones. This is the method used in today’s nuclear power stations to make electricity. Nuclear Fusion Nuclear fusion is what happens when two light nuclei combine and form a new, larger, nucleus. This reaction also releases a lot...
Triple fusion is the fusion of the male gamete with two polar nuclei inside the embryo sac of the angiosperm. This process of fusion takes place inside the embryo sac. When pollen grains fall on the stigma, they germinate and give rise to the pollen tube that passes through the style and...
to the energy released by fission or fusion of atomic nuclei, also known as atomic energy. Nuclear power generation is low-carbon and environmentally friendly, and the earth is rich in nuclear energy, but nuclear waste reprocessing and peaceful use of nuclear energy is still a long way to go...
The model dependence of the concept of "nucleon in nuclei" is emphasized, starting from the example of the ground state of nuclear matter. How to reconcile this model dependence with the necessary model independence of predictions for observables is discussed. As an illustration, the deuteron ...
