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.
The water cycle is also referred to as the hydrologic cycle.
Answer:
1.
3.
4.
Explanation:
In trial A, people have no immunity so there are more chances of infection and in trial C, only 50% of people have immunity so chances of infection are less, so infection will spread faster in trial A than trial C.
If compared, trial C will have less infected people than trial A because people in trial A has no immunity and people in trial C have 50% of immunity, so only fewer people will get infected even after six point of contact.
As percentage of immune people (trial C) is 50, so there are equal chances of immunity and non-immunity. there are three reasons of infection that include source, susceptible person and transmission. source and susceptible person can be the reason of infection in some non-immune people but the transmission reason can vary. s<em>o, there is probability that three nonimmune people lie under transmission reason and are not coming in contact with infected people, medical equipment or environment, that causes infection and those three people are not getting infected.</em>
<em>Hence, the correct options are 1, 3 and 4.</em>
