Answer:
Because of the angle of the Earth relative to the sun. The higher the sun is in the sky, the higher the UV radiation level.
Explanation:
So, the lattitudes toward the poles that receive sunlight are at an oblique angle, with that being said, the amount of radiation is spread to a larger area than the equator.
double stranded molecule does not describe the structure of RNA. Most RNA are single stranded with partial double stranded regions. RNA has basic component as the DNA that is have four nitrogenous base, contain phosphate group and have 5 carbon sugar.
Answer: The oxygen content at the source of the streams or rivers is higher as compared to the mouth of the river. Consequently, the organisms which require more oxygen tend to find at the source of the rivers whereas the organisms which require less oxygen tend to find at the mouth of the river.
Explanation:
Answer:
Of the five ocean basins, the Atlantic Ocean is the saltiest. On average, there is a distinct decrease of salinity near the equator and at both poles, although for different reasons. Near the equator, the tropics receive the most rain on a consistent basis.
Helium, with two protons, will have two electrons. In the chemical classroom, the proton count will always be equivalent to an atom's atomic number. This value will not change unless the nucleus decays or is bombarded (nuclear physics). Figure \(\PageIndex{1}\): The periodic table of the elements.
