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.
Answer:
The brackish water adaptation is clearly necessary because the aquatic snails need to live in an environment in which the river system has a higher quantity of salt than what land snails can take. I can determine that the environmental factors influenced the inherited adaptations because the second population has a higher salt concentration in their habitat compared to the initial population.
Hey!
8= B : adenine with thymine , guanine with cytosine.
9= False : its not single , *dual* helical structure.
10= Every humans' DNA is different but its as similar as our relatives' DNAs as far as i know so its False.
11 = The two backbones of the DNA molecule consists a deoxyribose sugar ^with 5 carbone^ and a phosphate so the correct answer is B
12= Procaryotes' Genomes are simpler- structured than eukaryotes' so procayotes DNA is 1/1000 of eukaryotes.I couldnt translate the options correctly (im not native sorry) but i think its B according to my knowledge of that XD
13= the amount of adenine, guanine, thymime and cytosine must be same so the correct option is %40as well.
Hope it helps!!!

Atmospheric Fixation. The enormous energy of lightningbreaks nitrogen molecules and enables their atoms to combine with oxygen in the air forming huge nitrogen oxides. These dissolve in rain, forming nitrates, that are carried to the earth.
Answer:
1.Blood pressure in the small capillaries pushes the fluid into a sack called Bowman's capsule. 2. It reabsorbs important nutrients that are in the filtrate. 3. The Loop of Henle descends from the cortex into the medulla and concentrations of salts in the interstitium increases. 4. Salts leave the filtrate using both passive and active diffusion. 5. Waste products ammonia and urea are transported into the filtrate for excretion, while calcium and sodium continue to be reabsorbed and water leaves the nephron. 6. The filtrate empties into collecting ducts, where it combines with filtrate from other nephrons.
