Answer:
They are more attracted by the oxygen atom than by the hydrogen atom.
Explanation:
The bond between hydrogen and oxygen atoms in a water molecular is polar in nature. This is due to the differences in electronegativity of oxygen and hydrogen. Oxygen is much more electronegative than hydrogen.
The higher electronegativity of oxygen atom means that it attracts the electrons of the bond towards itself. Hence, the electrons of the bond between hydrogen and oxygen atoms in a water molecule are more attracted towards oxygen atom due to its higher electronegativity.
The type of solution researchers should use to cause blood cells to lyse (burst) would be a hypoosmotic solution. It is a solution which has lesser solute concentration in relation with another solution. For instance, a cell of a fish from fresh water would be hypoosmotic to salt water.
Answer:
Chromosomes are made up of DNA(deoxyribosenucleicacid) which is a protein complex called chromatin that is organized into subunits called nucleosomes. The way in which eukaryotes compact and arrange their chromatin also helps regulate gene expression.
