The Proton
Atomic nuclei have two kinds of subatomic particles, which are protons and neutrons.
The centre of an atom is called the nucleus. The nucleus contains protons, which have a positive charge and neutrons which have no charge. Electrons are also subatomic particles but they go around the nucleus so they are not in the centre.
There are 3 kinds of Sub-Atomic particles. These are Proton, Electron, Neutron.
Chromatin is the substance associated with the structure of the nucleus. Chromatin is composed of DNA and proteins, and it is responsible for packaging and organizing the genetic material within the nucleus.
Electrons, which have a negative charge; Neutrons, which have no charge; and Protons, which have a positive charge.
Prokaryotic cells have no nucleus. In the human body, mature erythrocytes (red blood cells) have no nucleus.
One model of the atom has "subatomic particles": electrons, protons, neutrons. The protons and neutrons, according to this model, are made up of three different kinds of quarks each.
both a and b
The two basic kinds of cells are prokaryotic (bacteria) and eukaryotic cells, a eukaryotic cell has a nucleus and organelles, but prokaryotic don't have a nucleus and have ribosomes instead of organelles.
there are absulute location and regritive location
Protons && Neutrons ! Promise (:
