Answer:
Water molecules are polar and form strong hydrogen bonds.
Explanation:
Properties like high surface tension and boiling point are unique to water due to water's polar molecules. This allows water to form very strong hydrogen bonds and give it some different abilities.
Answer:
Hydrogen Bonds
Explanation:
The arrangement of phospholipid bilayer of plasma membrane is such that ; the polar phospholipid heads point outwards into the watery external environments. This Polar environment is Hydrophilic or water loving, while the water- hating hydrophobic tail region pointed inwards away from the watery medium.
This gives the usual bilayer shape to the plasma membrane,with the tail facing one another and heads outward.
The hydrogen bond is formed as inter molecular forces between the hydrogen atom (positive side)of water molecule and oxygen atom (negative side)of the polar molecules e.g glucose, to form an idea dipole -dipole force interactions,
Polar Compounds, glucose, urea dissolved easily in hyrophilic watery environment to from Hydrogen bonds with water
<u>The correct answer is Hydrogen bond a dipole dipole force</u>
Answer:
See the answer below
Explanation:
A DNase is also known as deoxyribonuclease and it is an enzyme that catalyzes the degradation of deoxyribonucleic acid by cleaving the phosphodiester linkage in their structures. Thus,<em> if the RNA is treated with a DNase before the plants are exposed to it, it will not make any difference. The plants will develop the same types of lesions as if they have been exposed to the mosaic virus.</em>
Unlike DNase, RNase is a ribonuclease, an enzyme that is capable of carrying out catalytic degradation of ribonucleic acids. <em>This means that if the RNA is treated with RNase before the plants are made to be exposed to it, they will not develop the lesions because the RNA would have been degraded by the enzyme.</em>
A protease is an enzyme that degrades the structure of proteins. <em>Treating a RNA with protease will thus have no effect on the structure of the RNA. Exposing the plants to the protease-treated RNA will make no difference. The plants will still come down with the lesions as if they have been exposed to the virus. </em>
