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>
They are most related to damselflies.
The sweet pea plants having a diploid 2n chromosome number of 14 produces F1 offspring with 14 chromosomes by the process of fusion of gametes each having n number of chromosomes.
<h3>What are diploid organisms?</h3>
Diploid organisms are organisms having two copies of each chromosome or 2n number of chromosomes
Diploid organisms undergo meiosis to produce haploid cells having n chromosomes.
Two haploid cells from each parent combine to produce offspring with 2n number of chromosomes.
Therefore, the sweet pea plants having a diploid 2n chromosome number of 14 produces F1 offspring with 14 chromosomes by the process of fusion of gametes with n number of chromosomes.
