The process of fermentation in winemaking turns grape juice into an alcoholic beverage. During fermentation, yeasts transform sugars present in the juice into ethanol and carbon dioxide (as a by-product).
Answer:
on N overlaps with 1s on H.
Explanation:
Hybridization of central atom generally can be found by finding the hybridization number.Hybridization number is the sum of number of lone pairs and number of sigma bonds.
If hybridization number is 2 then the central atom is sp hybridized.
If it is 3 it is 
hybridized.
If it is 4 it is hybridized and so on.
Here in 
molecule there are 3 sigma bonds and one lone pair(see the figure attached).
Hence hybridization number is 4 and hence it is s
hybridized.
And in case of hydrogen atom the only electron of it resides in the 1s orbital.
Therefore on N overlaps with 1s on H.
Answer:
The Earth rotates on its axis at a constant tilt.
Earths rotation on its axis at a constant tilt provides seasonal changes in the different part of the country. This resulted to the distribution of the heat of the sun from northern hemisphere and to southern hemisphere. Making areas with hot temperature may experience rainy season in a year. This will help production of crops or food supply and water supply available for living organism.
If the Earth's rotation is not tilted, then both the northern hemisphere and southern hemisphere will be covered with thick ice sheet. The equatorial region or near the equatorial region will experience tremendous warm temperature. Making our life on Earth not ideal for living.
Magnetic Field
Earth is protected by the magnetic from the dangerous radiation coming from the heat of the sun.
Water and oxygen
These two elements are essential for living organism in order to survive. The existence of waters proves that Earth temperature is conducive for living.
