Answer:
P (actually that randomly selected person has diabetes given as given by the lab) = 0.7725
Explanation:
A probability is a number, between 0 and 1, expressing the precise likelihood of an event happening.
Probability (person actually has diabetes) = 5.9%
P(lab test says that they have diabetes) = 0.0764
P (actually that randomly selected person has diabetes given as given by the lab) = 0.7725
Workings shown in the figure below.
Answer:
B. Open Stomata
C. Transpiration
Explanation:
Even though plants take up a lot of water from their roots, they lose about 95% of it to the atmosphere in the process known as Transpiration.
Transpiration is done for several reasons: it cools the plant down, it enables plants to access the nutrients in the water as the water moves along the plant and it enables gaseous exchange.
The gaseous exchange happens because carbon dioxide comes in from the same holes on the leaf that the water leaves through to the atmosphere, the open stomata.
Answer: The frequency of brown beetles is 0.32.
Explanation: The frequency of A1 allele is 0.8. As p+q=1, or the sum of dominant and recessive frequencies equals 1 or 100%:
1 - 0.8 = 0.2
In Hardy-Weinberg principle,
2pq represents the frequency of heterozygote individuals, so:
genotype A1A2 = 2*0.8*0.2 = 0.32.
Thus, the frequency of brown beetles (A1A2) in the population is 0.32.
