I would say B.
A, umm, don't crash trains, that's bad.
C, Lillian is wondering how fast a train can go, not at what curve will it fall.
D, Lillian isn't wondering about the size of the trains, just the speed.
Answer:
A
Explanation:
Some materials reflect light waves.
Answer;
-23 in males
In humans, 23 in males is the only homologous chromosome pair that isn't the same.
Explanation;
-In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
-Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.
-The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes.
Two major steps are needed to obtain a protein from a gene. Transcription makes it possible to obtain a copy of the gene present on the chromosome, in the form of a messenger RNA (mRNA). Translation is the stage during which this mRNA is read by the ribosome to obtain a protein.
DNA replication is associated with photocopy because replication will give an identical copy of the cell DNA.
Transcription is associated with book printing because in transcription the genetic information will be transferred to another platform (RNA)
Nucleus in a Library since this is where the "book printing" occurs, and where the books (DNA) are
DNA is the book, where all the information are
RNA transcript is the photocopy
Translation is the cooking since it is the protein synthesis
Proteins/polypeptide is the cooking objective, so it is the prepared dish
RNA polymerase is the Xerox machine, it will copy the information in the DNA to RNA transcript
Ribosomes is the cooks, because this is where translation occurs
Activator protein are the bookmarks because it choose wich part of DNA it has to be transcript.
Answer:
All of the options are true for a MRSA infection.
Explanation:
<em>Staphylococcus aureus</em> is one of the most frequent pathogens causing hospital and community infections. <em>S. aureus</em> can become very easy methicillin resistant (called MRSA isolates) and others beta-lactam antibiotics (are the ones widely used to treat infections) and usually can be resistant to other class of antibiotics, become a very strong bacteria making treatment options very limited. MRSA isolates can rapidly transfer the methicillin resistance to other species of S<em>taphylococcus</em> and some other bacteria. Also <em>S. aureus</em> can acquire other antibiotic resistant genes making a deadly bacterium for its strong resistance. It is in search how the bacterium acquire this antibiotics resistance ( and other virulence factors genes) and the mechanism involve to develop new drugs to treat MRSA infections with the hope that can´t develop resistance to this new drugs.
