Answer #1

Species diversity of plants is less than the animal diversity because of greater dispersal of the animal species and their higher survival rate. The animals possess the nervous system, which better regulate and coordinate their activities, it plays a key role in escape from the predators. Their adaptive responses ensure their survival in various environmental conditions. So, more number of animal species were evolved than the plants. Plants does not contain the nervous system, they are not mobile, so they respond in a different way towards the environmental stimuli

In the class we have discussed that bacteria can evolve much faster than animals and plants because they grow much faster and have larger population sizes. To put this in a context, do you think it is possible statistically that every single base pair in the E. coli genome has experienced a mutation in a 5 ml E. coli overnight culture? We know that there are ~1010 cells in the 5 ml overnight culture and the mutation rate of E....

The USDA reports that 22% of four-member households spend less than $100 per week on groceries. Suppose a random sample of 300 four-member households is taken. Find the probability that the sample proportion of households who spend less than $100 per week on groceries is between 19% and 29%.
