All galaxies have a dense core of stars. Spiral galaxies, however, have arms that are often visible. There are two kinds of spiral galaxies: barred, where there appears to be a line running from arm to arm through the core, and <span>ordinary, where there is no bar. @Badbunnyhunny</span>

Kay [80]
A. The variables in the problem include the miles traveled, the cost to rent the car and the cost per mile traveled in the car. 
b. The rate of change in the problem is the amount of payment that is expected per mile traveled.
c.The y-intercept is the total cost of the miles traveled without including the deposit.
d. A straight-line function will work for this problem, where y = mx + c.
m = $0.15, c = $25 and x = total miles traveled. 
e. y = ($0.15)(1200) + $25
       = $180 + $25 
       = $205

maxonik [38]

The right answers are:

A-present in eukaryotic genomes ==> Both exons and introns

B-generally absent from bacterial genomes ==> Introns

C-part of the final mRNA strand ==> Exons

D-code for an amino acid sequence ==> Exons

E-removed from initial mRNA strand prior to translation ==> Introns

F-present in the DNA used as the template for transcription ==> Both exons and introns

In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.
