A children's liquid medicine contains 100 mg of the active ingredient in 5 mL . If a child should receive 150 mg of the active i
wariber [46]

Answer:

The correct answer is 7.5 ml

Explanation:

The medicine contains 100 mg in 5 ml, that means that the concentration of the active ingredient is 100 mg/5 ml= 20 mg/ml

If we divide a concentration (in mg/ml) into a mass (in mg) we obtaine a volume (in mL). Thus, in order to calculate the mililiters of medicine which contain 150 mg of the active, we have to only divide mass (150 mg) into the concentration of active ingredient as follows:

mL = \frac{150 mg}{20 mg/mL}= 7.5 mL

Species a diverged from species b 60,000 years ago. On a particular gene, they have 15 nucleotide differences. How many nucleoti
a_sh-v [17]

The given question says that b species diverged around 60,000 year ago from species a. Since the divergence, they have a nucleotide difference of 15 nucleotide.

We need to find out the nucleotide difference in another 240,000 year, which means a total of 300,000 year since divergence.

The nucleotide difference in 60,000 years = 15 nucleotide.

The nucleotide difference in 1 year =\frac{15}{60,000}  nucleotide.

The nucleotide difference in 300,000 years = \frac{15}{60,000}\times 300,000 nucleotide.

The nucleotide difference in 300,000 years = 75 nucleotide.

Hence, after another 240,000 years or 300,000 years since divergence, the species and species b would show a difference of 75 nucleotide.

In another 240,000 years, there would be 60 nucleotide difference, as 15 of the nucleotide are already different in initial 60,000 years from the total of 75 nucleotide difference in 300,000 years. So, 60 (75-15) nucleotide difference would be observed in next 240,000 years.

How does the structure of the bronchial tree change as the bronchi become smaller?
insens350 [35]

The following structural changes occur as conducting tubes become smaller;

- support structures change. The trachea has more hyaline cartilage than the bronchioles

- epithelium type changes with bronchioles having ciliated columnar cells with the trachea having tall       columnar pseudostratified

- amount of smooth muscle increases as you go lower the respiratory tract
