What part of the cell controls a bacterial cell?
it is DNAor nucleus..The above answer is wrong. Bacteria do not have a nucleus as they are prokayotic, meaning before nucleus. Bacteria also do not have DNA as it is not necassary for their purposes. Instead they have RNA, (Ribonucleaic Acid as opposed to Deoxyribonucleaic Acid). The RNA is single stranded in a circle as opposed to the double stranded DNA of humans. This structure allows the RNA to be quickly translated into protein. So the answer would be RNA that is "free floating" inside the bacteria.The control center of a cell is the nucleus. The DNA has the instructions for the cell which is the control center as well.
Is barium an ionic bond?
No. An ion is a positively or negatively charged atom, or group of atoms due to more or less electrons than necassary. Both barium and sulfate are ions, but together they are a compound, not an ion. Barium Sulfate is a chemical compound made up of two ions, a barium ion and a sulfate ion. A Barium ion is Ba+2, meaning it has two less electrons that a barium atom has. The reason for this is because the barium atom has 56 total electrons. Every atom wants to be ion with a filled valence shell, that is to have the same or similar electronic configuration of a noble gas (the elements in the right most column). The valence shell is the outermost shell of electrons and for barium the other shell is 8 electrons. In order for Barium to do this, it has to somehow lose 2 electrons to become similar to Xenon's electronic configuration. Sulfate, SO4 -2, is also an ion. the -2 means it has aqcuired 2 more electrons from another ion. It got those two electrons from the barium atom, simultaneously making the barium atom a barium ion. Sulfate is called a polyatomic ion, meaning an ion made up of more than 1 atom. When the barium ion gives the sulfate ion two electrons, thus making both electronic configurations "happy" they bond together to make an ionic bond, creating the compound barium sulfate.
How do waves in an earthquake get their names?
The word earthquake is another word for earth shake. The definition of quake means to shake or tremble and during an earthquake the area is continuously shaking until the earthquake has ended. Therefore, scientists believed that earthquake was the perfect name.
