Given:
It takes 14.5 hours to produce 200 bushels of wheat on 5 acres of land.
Part (a)
Because 23 acres will hold more wheat than 5 acres, the number of bushels that can be planted on 23 acres is
(23/5)*(200 bushels) = 920 bushels.
Answer: 920 bushels
Part (b)
If the number of workers remains the same, it will take them longer to plant more bushels.
The time required s
(920/200)*(14.5 hours) = 66.7 hours
Answer: 66.7 hours
Answer: The population density of one's current geographic residence.
Explanation:
Daniel Kennedy and Ralph Adolphs, both from the California Institute of Technology, noted in an essay published in the same issue of Nature.
Kennedy and Adolphs noted that city populations might, to a certain extent, be a self-selecting population. "There are wide variations in individuals' preferences for, and ability to cope with, city life: some thrive in New York City; others would happily swap it for a desert island," they wrote in their essay. One key reason for this might be "the perceived degree of control that people have over their daily lives."
Kennedy and Adolphs Also suggested future work focusing on ways of "softening" the urban landscape via better architecture and urban planning.
Even though city dwellers showed differences in their brains, their levels of the stress hormone cortisol was on par with their rural peers.
Social threat, lack of control and subordination are all likely candidates for mediating the stressful effects of city life, and probably account for much of the individual differences."
Dr Daniel Kennedy and Prof Ralph Adolphs, both at the California Institute of Technology, said that there are wide variations in a people's preferences for, and ability to cope with, city life.
Answer:
the value of the dominant allele is roughly 0.02.
Explanation:
The Hardy-Weinberg equation should be used to test whether a population is evolving or not. Since there are two alleles for a given locus, we will call the dominant allele (p) A, and the recessive allele (q) will be called a. Thus, p will be the allele frequency of A and q will be the frequency of a, so we will have p + q = 1 since the sum of these two alleles will equal 100%.
So if 96% of the population of the question is recessive, we can find the value of q, which will be the result of the square root of 0.96 which is approximately 0.98.
From this value, we use the formula (p + 0.98 = 1) to find the value of the dominant allele, which is 0.02.
This means that 0.004% of the population has the AA genotype and 0.016% has the Aa genotype, while 96% have the aa genotype.
