Answer:
<em>The correct option is C) OH</em>
Explanation:
In the field of chemistry, radicals can be described as atoms, molecules or ions which have at least one unpaired electron.
The formation of a radical occurs when a single covalent bond breaks so that each of the atoms that had been involved in the formation of the covalent bond can have an unpaired electron. Examples of radicals include OH, NH4+ etc.
Other option, like option B, is not true because a molecule of water does not have any unpaired electrons in its valence shell.
Answer:
One
Explanation:
RNA is a single-stranded molecule
Answer:
The correct answer is option 3. "secondary structure".
Explanation:
The secondary structure of polypeptide and proteins refers to the second order of folding, including common structures such as beta sheets, alpha helix, as well as turns and loops. The hydrogen bonds between the oxygen and nitrogen atoms of the peptide bonds are crucial to secondary structures, as these hydrogen bonds form and stabilize the aforementioned common structures.
Answer:
The Temperate Deciduous Forest is a biome that is always changing. It has four seasons: winter, spring, summer, and fall. Constant rainfall and daylight saving hours also contribute.
Explanation:
Temperate deciduous forests get between 30 and 60 inches of precipitation a year, this helps keep the forest lush and green. When it comes to daylight savings in the fall, lack of sunlight can affect photosynthesis and the amount of sun the plant gets. Unlike the amazon forest, the temperate biome goes through all 4 seasons and has plant regeneration in the spring instead of constant vegitation.
Hope this helps :)
Answer:Sandstone and shale are sedimentary rocks. Dynamic geologic forces created Earth's crust, and the crust continues to be shaped by the planet's movement and energy. Today, tectonic activity is responsible for the formation (and destruction) of crustal materials.
