A hydrogen bond is formed when a positively polarized hydrogen atom in one molecule is attracted to a highly electronegative atom in another molecule. In the example of water molecules, the negatively charged oxygen atom in one water molecule attracts the positively charged hydrogen atom in another water molecule. Oxygen atoms tend to steal electrons away from the hydrogen atoms within molecules. When this occurs within a water molecule, the electron loss creates a hydrogen atom with a partial positive charge, which is then attracted to a negatively charged oxygen atom in another water molecule.
The hydrogen bonds that form between water molecules cause them to stick together. This gives water a high boiling point temperature because a greater degree of heat energy is required to break the intermolecular hydrogen bonds. Many organic substances that are required to sustain life, such as nucleic acids and proteins, contain hydrogen bonds. Although these bonds are weaker than the internal ionic or covalent bonds existing between the atoms within molecules, the accumulated strength of hydrogen bonds within living organisms is highly significant and plays an important role in maintaining stability.
The characteristics that makes golden eagles successful hunters is their good eyesight and their large wingspans.
<h3>The characteristics of a golden eagle:</h3>
The golden eagle is one of the most widespread eagle in the world.
That is because they are able to adapt in almost every type of climate, especially open areas with vegetation.
Some of the characteristics that makes them successful hunters is the good eyesight and large wingspans they possess.
Taking the vision of human beings for example, what looks sharp and clear to us at 5 feet is just as clear to a golden eagle from 20 feet away.
Also, their large wingspans helps then fly long distance in search of preys.
Therefore, the characteristics that makes golden eagles successful hunters is their good eyesight and their large wingspans.

C ecological efficiency is the answer
Answer:
D)clues about the past climate of Earth
Explanation:
The fossil record certainly has gaps, mostly because the conditions required to create fossils have been rare ever since life began on Earth. A very small percentage of animals that have lived and died ever became fossils. Thus, many pieces of the puzzle are missing; some will never be found.
Answer:
The answer should be the third option. 'All animals are multicellular heterotrophs'
Explanation:
