Are SA citizens vaccinated against yellow fever? give two reason for your answer.
Brut [27]
South African people are vaccinated with Yellow fever. First, SA is strict in the implementation proof of vaccination in travelers coming in the country. The vaccination card must show vaccination at least ten days prior to travel. This is to prevent reintroduction of the disease to SA people. Second, In the list of Center for Disease Control, South Africa is not included in the countries with an endemic Yellow fever which means that the disease is wiped out if not controlled through vaccination.

The diagram shows the process of meiosis. How many divisions are required to decrease chromosome numbers and produce gametes?
Tresset [83]

The right answer is 2 divisions.

Meiosis follows the replication of DNA from a reproductive cell (male or female). It allows the passage of a so-called diploid mother cell to 2n chromosome homologous chromosomes to 4 single-chromosome haploid daughter cells. For that it must pass by two successive divisions, the first division is reductionelle generating two diploid cells with n chromosomes. the second division is equational giving 4 haploid cells to n chromosomes from the two preceding cells.
