Answer:
Acid deposition-usually referred to simply as acid rain-actually includes two forms of pollution, wet and dry. ... In the wet type of acid deposition, these compounds combine with water vapor in the atmosphere to form highly corrosive sulfuric and nitric acids.
Explanation:
The accumulation of acids or acidic compounds on the surface of the Earth, in lakes or streams, or on objects or vegetation near the Earth's surface, as a result of their separation from the atmosphere. Acid deposition can harm the environment in a variety of ways, as by causing the acidification of lakes and streams, the leaching of minerals and other nutrients from soil, and the inhibition of nitrogen fixation and photosynthesis in plants.♦ The accumulation of acids that fall to the Earth dissolved in water is known as wet deposition. Wet deposition includes all forms of acid precipitation such as acid rain, snow, and fog.♦ The accumulation of acidic particles that settle out of the atmosphere or of acidic gases that are absorbed by plant tissues or other surfaces is known as dry deposition.
Blood type is determined by the alleles coding for the antigen present on cell membranes.
The person with type AB blood has a heterozygous Rh factor.
- Half the gametes have Rh factor (+) and the other half are negative for Rh factor (-)
- Half the gametes have IA and the other half have IB
- The possible gamete combinations are IA+, IA-, IB+, IB-
The person with heterozygous type A blood is negative for Rh factor
- All gametes are negative for Rh factor (-)
- Half the gametes have IA and the other half have IO
- The possible gametes are IA-, IO-
The genotype ratio is 1:1:1:1:1:1:1:1
The phenotype ratio is 2: 2:1:1:1:1.

The thermodynamic barrier that must be overcome before products are formed in spontaneous reaction is activation energy.
The activation energy is the maximum amount of extra energy that is required by a reacting molecules to get converted into product. It is the minimum energy that is required or needed to activate or energize molecules or atoms.
It is needed in the reaction so that reactants can move together and overcome forces of repulsion and start bond breaking.
Reactant is the substance that takes part in and that undergoes change during a reaction.
