Red invasive fire ants (RIFA) are costly because they can cause severe damage in variety of fields like in agricultural crops, in constructed building as well as electrical equipment. They can even kill the tissues of the person they sting by injecting some poison on to the area.
RIFA are the species of ants that are native to South America. They are simply called the fire ants. The species are believed to be spread in the soil carried through the cargo ships that then became spread profusely. Since they can reside at any area they are estimated to cause million dollars of damage every year.

Simply put, it is a physical trait that is expressed across a population, resulting in subtle changes. However, the immediate changes do not primarily affect the offspring. It can likewise be characterized with regards to the Strong Weinberg harmony - "the allele frequencies change assuming any of the rules of Solid Weinberg balance isn't satisfied".
It's also important to remember that the accumulation of changes from the microevolution process can lead to speciation, which serves as a raw material for the macroevolution process.

Beneficial mutations are alterations in DNA sequences that produce changes in the individual, leading to their adaptation and increasing their fitness. In the exposed example, the mutation is beneficial.
What is a mutation?
A mutation is a change or alteration in DNI sequences that introduce new variants.
Many of these mutations are eliminated, but some of them might succeed, be incorporated into each individual, and spread in the population. These mutations are the ones that have been selected by natural selection.
Mutations can be damaging, beneficial, or have no effect on the individual.
When beneficial, mutations produce changes that help the individual adapt to an environment, and increase fitness. These are cases in which mutations are essential to evolution.
In the exposed example, the mutation that causes white fur favors foxes, driving them to a better adaptation to their polar white environment and to their fitness increase.
Foxes with white coats get to camouflage better in the substrate. They can hide from predators and be unnoticed by their prey. These two events increase their survival and reproductive rates.
According to this reasoning, the mutation can be classified as beneficial.

2. explain the mechanisms of cis and trans regulation that allow for normal splicing of eukaryotic pre-mrnas.
RNA splicing puts together the protein-coding regions (exons) and cuts out the intervening, non-coding segments of genes (introns) from pre-mRNA.
The majority of splicing happens between exons on a single RNA transcript, but trans-splicing, in which exons from various pre-mRNAs are ligated together, occasionally happens. The splicing procedure takes place in cellular machines called spliceosomes, which also contain additional proteins and the snRNPs.
The joining of exons from the main RNA in a 5′ to 3′ order is known as cis-splicing. Exon scrambling is the joining of exons from the main RNA in such a way that the 3′ and 5′ exons are placed in front of each other. The linking of exons from several parent RNAs is known as trans-splicing.
regulators of cis and trans-splicing that affect spliceosome activity/binding
RNA patterns called exonic/intronic splicing enhancers/suppressors serve as cis regulators (e.g., ESE)Trans regulators are proteins that bind cis motifs; these proteins compete with tissue-specific regulators and repressive heterogeneous nuclear ribonucleoproteins (hnRNPs) to promote splice site usage.To know more about RNA splicing visit the link:
