Stephanie growing five
bean seedlings in a lighted area and five bean seedlings in a dark area is the
best experimental procedure if she wants to do an investigation about
the effect of light on the growth of bean seedlings.
Cystic Fibrosis is a genetic disorder passed through a recessive gene. Often this condition is first diagnosed when the patient is a child by using a sweat test. Cystic Fibrosis affects cells that produce mucus, sweat, and digestive juices, causing these fluids to become thick and sticky. This causes a cough, repeated lung infections, the inability to gain weight (developmental issues), and fatty stools. Patients can take a mucus thinner medication which helps temporarily thin the mucus in their airways, allowing them to cough it out of their lungs more easily. Another treatment is using vest therapy. The vibration of the vest against the chest wall helps loosen mucus, creating airflow that will move the mucus away from the airway walls. The patient must then cough periodically during and after the treatment to clear the fluid.
<span>Juana performs the calculation below. 6.05 + 3.156 + 5.0
</span> 1
6.05
+ 3.156
<span><u>+ 5.0 </u>
</span> 14. 206 =>The answer has 5 significant figures.
Here are the three rules on determining how many significant figures are in a number that you must remember:
<span>-Non-zero digits are always significant.
-Any zeros between two significant digits are significant.
<span>-A final zero or trailing zeros in the decimal portion ONLY are significant.</span></span>
Answer:
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
Explanation:
Within the body, bacteria can divide (multiply) and kill host cells by disrupting their normal functioning. Moreover, bacteria secrete toxins that are able to destroy host cells' metabolic machinery. For instance, many bacteria synthesize exoenzymes and interferons that disrupt and destroy host cells. Bacterial toxins can be synthesized internally in order to develop sensitivity through antigenic properties.
