In recent years, there have been outbreaks of diseases like Zika, Ebola, and Swine Flu. Given what you know about biological causes of diseases, describe what you think the characteristics of the next big outbreak will be. Will it be caused by a multicellular parasite a protist bacteria virus or prion? Will it be airborne, food borne, waterborne, or vector borne? Explain each of your answers.

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project

a=c and then d= c because of the band so you get ac/dc and you add them together you get sound waves

we solve the problem using the hardy-wineberg equation.

let us start with the homozygous recessive proportion of individuals with sickle cell anaemia,

we have the proportion as q² = 0.25.

∴ q = 0.5 (frequency of hbs in population)

further,

solving for the frequency of normal cell by using the fact that,

p + q = 1

∴ p = 1 - 0.5 = 1 - 0.5 = 0.5

now we can calculate 2pq in p² + 2pq + q², which is the frequency for heterozygous carriers of sickle cell anaemia,

∴ 2pq = 2 x 0.5 x 0.5 = 0.5

and the homozygous normal cell individuals proportion is given by the expression,

∴ p² = 0.5² = 0.25

hence, the carriers for sickle cell anaemia are in proportion, 0.5, or 50%.
