Answer:
The Nucleus...
it perform many activities and stores DNA in a cell.
Answer:
The answer is below
Explanation:
The density of an object is its mass per unit of volume. Dense objects feel very heavy for their size, while for objects with low density they are very light for their size.
Density is the ratio of mass to volume; it is given by:
Density (D) = mass (m) / volume (V)
An object sinks in water if the density of the object is greater than the density of water. While an objects floats on water if the density of the object is les than the density of water
<span>A bond between two atoms in which the shared electron or electrons are equally likely to be found near each atom is called a non Polar Covalent Bond.
Explanation:
As we know atoms react in order to gain stability. Now, the bonding is done by several ways. Among these ways one is the mutual sharing of electrons between two atoms. Neither one completely accepts nor donate the electron instead they share it equally. If this sharing is purely equal then the bond formed is non polar in nature (like bonds between similar atoms), on the other hand if this sharing is not equal then one atom will get partial positive (less electron density) and other will get partial negative (more electron density) charge like in HCl.</span>
In his proposed model of the atom, J.J. Thomson imagined the atom contained<u><em> electrons and space filled with wispy positive charge </em></u> .
I hope this helps you and have a great day!! :)
