Suppose that the number of newborns (N) in an insect population can be predicted from the number of adult insects (I) according

to the following equation, where r and b are variables related to the rates of population growth: N=rI−bI2. Calculate N if r=1.5, b=0.0015, and I=500. Rounding to the nearest whole number, N equals which of the following?
a) 1880
b) 375
c) 188
d) 749

Answer:

d: 749

Explanation:

From the equation, N = rl - bl2, where N is the number of newborns, l is the number of adult insects, and r and b are variables; with all the components given, N can be calculated by direct substitution.

Since r = 1.5, b = 0.0015, and l = 500, therefore, substitute for r, b, and l to get N such that;

N = 1.5(500) - (0.0015)(500)2

         750 - 1.5

N = 748.5

Rounding to the nearest whole number. N = 749.

<em>The correct answer is d.</em>

Are the counts of blue crabs in Maryland accurate for 1991 and 1999?
kirill [66]
The population of blue crabs will be difficult for the scientists to count because of unreliable ways and natural phenomenon or occurrence that causes the water's temperature to rise. According to climate reports, year 1999 have warmer temperature and this probably caused the blue crabs to be active, but on year 1990 female blue crabs sustained a normal quantity of production of their species. Thus, the estimated count of population of blue crabs is probably more accurate in year 1990 than year 1999 because of the stable production of the female crabs.

Illusion [34]

Answer:

d. Ribosome

f. Cell wall

Explanation:

In humans 80s type of ribosome is present and in bacteria 70s type of ribosome is present. Human cells do not have cell wall while bacterial cells have peptidoglycan cell wall. These differences can be targeted by the potential antibacterial agents.

For example, tetracycline antibiotic inhibits the binding of important molecules to bacterial ribosome which ultimately inhibits the protein synthesis in bacteria. Vancomycin antibiotic on other hand inhibits the cell wall formation in bacteria by inhibiting peptidoglycan synthesis.
