<span>These tests are listed in order of increasing rigor. The PAR-Q is a written assessment that predicts one's readiness for exercise. The other three require the help of a health professional to complete. Medical screenings and medical evaluations are both performed by a doctor, but the medical evaluation is more in-depth. Finally, the exercise stress test is designed to test the response of the body while exercising vigorously. This test is usually only used when a problem is suspected that could endanger the participant's life. (This is the word-for-word answer, so make sure you reword this before you answer the question.)</span>
a. A translation stop codon is added at the 3' end of the pre-mRNA.
c. A poly-A tail (50-250 adenine nucleotides) is added to the 3' end of the pre-mRNA.
d. Coding sequences called exons are spliced out by ribosomes.
Explanation:
In eukaryotes, during protein synthesis, the RNA must exit nucleus through the pores on the nuclear membrane and enter into the cytoplasm to undergo translation.
The exit processes of mRNA are: the 5’ capping, 3’ Poly-A tail, and pre-mRNA splicing.
The 5’capping is the initial step with addition of 7-methylguanosine cap to the 5’ end of the mRNA by phosphate linkage. This process protects the mRNA from degrading and helps to initiate translation processes.
The 3’ Poly-A tail step is the cleaving of pre-mRNA and addition of addition of around 200 A nucleotides or the 3’poly (A) tail to the mRNA by the poly (A) polymerase enzyme protein complex. This prevents pre-mRNA degradation, facilitates movement of mRNA to the cytoplasm, and initiates translation.
Pre-mRNA splicing is done to remove the introns from the mRNA because they are not part of function protein coding. The exons which take part in protein coding sequence are spliced once the introns are excised.
Finally, the resultant mRNA will exit the nucleus and enter the cytoplasm to undergo translation

Answer:
According to rational-emotive behavior therapists, the source of much unhappiness is: <u>d. system of inappropriate beliefs.</u>
Explanation:
This type of therapy explains unhapiness by the beliefs a person has. It also states that a change in the belifs would change the sense of how a person feels. A inappropiate sytem of beliefs would be the responable for unhapiness, and so this therapy works with changing the irrational or not producitve beliefs.
Answer:
