Answer: Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
It's impossible for it to be summer and winter in the same hemisphere because the southern and northern hemispheres have their seasons inverted. For example; when it is summer in the US it is winter in Australia.
Hope this helps :)
Answer:
D. Different functional groups and different physical and chemical properties
Explanation:
A functional group is an atom or group of atoms within a molecule that determines the chemical and physical properties of the compounds it appears in.
The functional group of an alcohol is the -OH group while that of an ether is an oxygen atom bonded to two alkyl or aryl groups, R-O-R'.
Based on the above;
Option A is wrong because they have different functional groups, hence different properties
Option B is wrong because they don't have same functional group even though their properties are different
Option C is wrong because they have different properties even though they have different functional groups
Option D is correct because they have different functional groups and different properties.
Explanation:
A synthesis reaction: It is defined as a kind of reaction where one and more than one reactant attached and creates an individual product.
The formation of the water is an example of a synthesis reaction because here more than one reactants combine and create a single product (water). Water formation occurs when 2 hydrogens and an oxygen share electrons through covalent bonds.
2H + O ----> H2O.
As sunlight heats Venus' surface, the surface radiates infrared energy that is kept from escaping the planet by dense carbon dioxide atmosphere. This is called the greenhouse effect.
