Can you see the nucleus under a compound microscope?
http://www.fidelitysystems.com/Unlinked_DNA.html contains a photo of DNA obtained via an electronic microscope. Note added by another user: This is NOT a photo of DNA under a compound microscope. This is DNA under a scanning electron microscope.
Where are each of the subatomic particles found?
There are something like several hundred subatomic particles. Most are only found under very special circumstances, such as the extreme conditions created in a particle accelerator. Here are some special cases:* The proton and neutron are found in the nucleus of the atom. * The electron is found surrounding the nucleus of the atom. * The quarks are found inside protons and neutrons (and other particles). * Gluons hold the quarks together.
Does a nucleus undergo cellular respiration?
No,nucleus do not under go respiration.Organell is the mitochondria.
Is electron an example of a lepton?
Yes. In physics, electrons are defined under the classification of leptons. Yes. Leptons are a class of elementary particles that interact with each other by the weak interaction. The electron is one of these particles.
How does radioactive decay transmute elements?
A radioactive element has unstable atomic nuclei. These nuclei will decay according to the decay scheme for that given element under inspection. Depending on the type of decay, an alpha particle (a helium-4 nucleus), or a beta particle (an electron or a positron, depending) may be ejected from the nucleus. This will result in nuclear transformation. With each decay, a "new" nuclear configuration will appear, and these nuclei will, if they are also unstable, undergo further radioactive decay along what is called a decay chain. With continued decay, the atoms will change and reach the end of the chain, and this will be signaled by the appearance of a stable atomic nucleus.
What do we mean when we say a nucleus has undergone an electron capture process?
You will recall that electrons orbit the nucleus of an atom (or in quantum mechanical terms, they surround the nucleus as a cloud). Under some circumstances, one of those orbiting electrons can fall into the nucleus, where it will react with a proton and convert it into a neutron. This is an electron capture process.

Can really be an electron seen under microscope?
only under an electron microscope wiki it

What are the charges on the nucleus and on the electron of an atom?
The charge on an electron and proton is 1.602 * 10^-19 Coulombs. Neutrons have no charge. The electron is considered to be a negative charge and the proton positive. The nucleus of an atom is made up of protons and neutrons so it will always be positive. However, the total charge depends on the atom. If you look at the periodic table of elements, the number of protons in an atom increases as you go left to right and up to down. The number of protons the atom has is the same as the number you see the element listed under. I.e. Hydrogen has 1, helium has 2, lithium 3, beryllium 4...etc. So if you wanted the charge on the helium nucleus, it would be 2*(1.602*10^-19).
Under what condition is heat transferred from one object to another?
Heat normally flows from a warm object to a cool object

Does a basophil have a nucleus?
Yes Basophils contain large cytoplasmic granules which obscure the cell nucleus under the microscope.The nucleus usually has 2 lobes.
What is the same as the number of protons in its nucleus?
The number of protons in an atomic nucleus can change by several different mechanisms. Let's look at each one and see what happens.In an atom with "too many" protons in its nucleus, that unstable atom can undergo what is called beta decay. There are two types of beta decay, and the one that could happen here goes by the name beta plus decay. In beta plus decay, a proton in the nucleus of that unstable atom transforms into a neutron. A positron and an antineutrino will be ejected from the nucleus, and the number of protons will have gone down by one. If you guessed that nuclear transmutation has just occurred where one element has transformed into another one, you'd be correct.In some other unstable atoms with "too many" protons in the nucleus, that nucleus could under an electron capture event. In electron capture, the nucleus "pulls in" a nearby electron from one of the inner shells of the atom, and that electron "combines" with a proton to become a neutron. Again, the number of protons in the nucleus goes down by one, and nuclear transmutation has occurred.Lastly, it is possible to bombard atomic nuclei with particles and "knock" protons out of a nucleus that is "hit" by the bombarding particles. There are a few different activities that are carried out in nuclear physics labs to do this, but we'll leave it here for now. Just keep in mind that beta plus decay and electron capture are the two primary methods that unstable nuclei undergo when they change the number of protons they have.
