In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.
Answer:
DNA
Explanation: Because if you stretch DNA it gets longer.
The balanced equation for the generation of sugar from
sunlight water and CO₂ is
6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
carbon dioxide + water → sugar + oxygen
<span>The process of photosynthesis occurs
when the chlorophyll present in the leaves of plants absorb sunlight to make
food in the presence of carbon dioxide (enters through the stomata of leaves)
and water (absorbed from the roots). As a result of this reaction sugar and
oxygen is formed. After that sugar is converted in to starch and oxygen is released
into air.</span>
