Answer:
it is expected to observe two bands: one band of light density and one band of heavy density
Explanation:
DNA replication is semiconservative because when DNA is replicated both resulting DNA molecules are composed of one original strand and one newly synthesized strand. If DNA replication would be conservative, then the original DNA molecule would serve as a template to produce a new DNA molecule, thereby each cell division would produce one daughter cell with a new DNA molecule and one daughter cell with the original DNA molecule of the parental cell. In this case, the transfer of bacteria-like organisms into a heavy 15N medium would produce two types of DNA cells after replication: cells with original DNA of light density (14N) and cells with new DNA of heavy density (15N), which would be distributed in two bands after centrifugation.
Answer:
Rate and tidal volume
Explanation:
Tidal volume is the volume of air moved in or out of the lungs with each normal breath. A normal tidal volume is around 500 to 600 mL per inspiration and/or 6 to 7 mL per kilogram of body mass. An Emergency Medical Technician (EMT) should assess the respiratory rate (as well as rhythm and quality), having into account that a normal respiratory rate in an adult is 12 to 18 breaths per minute (BPM). Moreover, an appropriate tidal volume is also fundamental in assisting individuals in respiratory distress and arrest.
<u>Answer:</u>
The pathophysiology instructor will emphasize that the cells of the proximal tubule have a fine, villous structure that increases surface area, allowing for active transport processes to occur with fluids.
<u>Explanation:</u>
- The proximal tubule is a part of the nephron and it controls the "pH of the filtrate" by exchanging "hydrogen ions for bicarbonates".
- It also secretes organic acids like creatinine and bases to be mixed with the filtrate, so that it is neutralized.
- Thus it helps in the transportation of the filtrate and is also responsible for absorption and re-absorption of the fluids.
