Developing countries share a number of common characteristics.’ Firstly, give an account of these common characteristics. Secondly, discuss any one characteristic in a country of your choice and analyse how this condition poses a challenge to the country. Your essay should be split equally between these two parts (50)
Samples of size 25 are selected from a population with a mean of 40 and a standard deviation of 7.5. What is the mean of the sampling distribution of sample means?
of 10 genes studied in yeast, 7 are found to form a network of metabolic interactions. If this set of 7 genes was chosen arbitrarily from the 10 that were studied, how many different sets would be possible? Show your calculation and the reasoning.a
Human colour vision is “produced” by the nervous system based on how three different cone receptors interact with photons of light in the eye. These three different types of cones interact with photons of different frequency light, as indicated in the following chart:
Cone Type Range of Light Frequency Detected
S 6.00-7.49 x 1014 s-1
M 4.76-6.62 x 1014 s-1
L 4.28-6.00 x 1014 s-1
What wavelength ranges (and corresponding colours) do the three types of cones
detect?
Implement the following functions. The functions return a real number:
(a) Function Celsius returns the Celsius equivalent of a Fahrenheit temperature ((32°F − 32) ×
5/9 = 0°C).
(b) Function Fahrenheit returns the Fahrenheit equivalent of a Celsius temperature.
((0°C × 9/5) + 32 = 32°F)
In main call both functions and ask user to input value of temperature and print its equivalent.
