What are the 4 organic molecules and relate the molecular structure of each? What type of bonds hold the two chains of DNA together in a DNA molecule? A) hydrogen B) polar covalent C) nonpolar covalent D) ionic E) more than one of these ...
Water is polar, meaning its overall charge is unevenly distributed. Hydrogen gets pulled towards the oxygen. Hydrogen is partially positive, so the region on hydrogen is partially positive. (Oxygen is negative) What type of bonds are between the hydrogen and the oxygen in a water molecule?
The purine and pyrimidine bases form hydrogen bonds to keep the two rails of the DNA molecule together. Adenine and thymine form two hydrogen bonds while guanine and cytosine form three. Hydrogen bonds are electrostatic forces between electrically charged parts of a polar molecule rather than chemica...
All lipids are made up of the same atoms: carbon (C), hydrogen (H) and oxygen (O). Lipids contain the same elements that make up carbohydrates but in different proportions. Lipids have a large proportion of carbon and hydrogen bonds and a small proportion of oxygen atoms. Although the st...
Answer and Explanation:1 A carrier molecule is a protein that helps transport a substance or electrons across a barrier. Carrier proteins usually allow the transport of polar... Learn more about this topic: Carrier Proteins | Definition, Functions & Examples ...
Nikki has a master's degree in teaching chemistry and has taught high school chemistry, biology and astronomy. Defining Dipoles and Dipole Moments Dipolesform when the electrons are unevenly shared in the covalent bonds, creating partial positive and negative charges on all atoms involved. The atom...

Biology : What are the charges on the water molecule?Polar Molecule:In some molecules, due to the arrangement of atoms, unequal sharing or distribution of electrons occur between the atoms of the molecule such that one end of the molecule becomes positively charged while the other end of the...
(the hydrophilic part) forms the outer surface of the micelle and is exposed to water. The lipophilic portion of the molecule (which is hydrophobic) is shielded from the water. Anyoils in the mixture are isolatedwithin the interior of the micelle. Hydrogen bonds stabilize the hydrocarbon chains...
