Sulphur dioxide reaches the atmosphere, it oxidizes to first form a sulphate ion.

The sulphate ion joins with hydrigen atoms in the air and becomes sulphuric acid. This then falls back down to earth as "acid rain"

Answer:
D.DNA-mRNA-Amino Acid-Protein-Trait
Explanation:
The relationship between DNA and the trait of an organism involves a process called GENE EXPRESSION. DNA is a molecule that contains information needed for the survival of an organism. However, this information must be expressed in order to be used.
The process of gene expression involves two major processes namely: transcription and translation. Transcription involves the synthesis of mRNA from DNA template while translation involves the synthesis of amino acid sequence from mRNA. The amino acid sequence encodes PROTEIN, which determines the TRAIT of an organism.
Based on this explanation, the correct sequence that best represents the relationship between DNA and the traits of an organism is: DNA-mRNA-Amino Acid-Protein-Trait
Answer:
The biological concept of evolution.
Explanation:
The process by which living organisms defy the environment that they habit and shapes every single trait of them. According to evolution every species that has ever existed in this world has suffered modifications by different reasons (mutation, for instance) and environment was the responsible to select the ones that were more suitable to last. The process of evolution can be delusional because it may be necessary millions of years to fulfill its mechanisms, specially in complex organisms like mammals.
<span>Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. (Domesticated) animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as (varieties), cultigens, or cultivars. Two purebred animals of different breeds produce a (crossbreed). Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. </span>
