A. Simplicity

B. Flexibility

C. Data quality

D. Acceptability

E. Sensitivity

F. Predictive value positive

G. Representativeness

H. Timeliness

I. Stability

Sensitivity, Predictive value positive, representativeness and timeliness.

Explanation:

In order to detect outbreaks and thus group people based on greatest risks, it is mandatory for a surveillance system to be sensitive and thus detect a reasonable amount of cases in the community alongside changes in severity of cases over a period of time. It is also expected that there is high predictability and be representative of cases in the community capable of describing the occurrence of disease by person, time ad place. It should also be timely in its execution, without any delays, as this will allow investigation and control measures to commence quickly.

the answer is "meiosis ii in the mother".

the procedure of meiosis includes two divisions of the hereditary material. the main division is known as the decrease division – or meiosis i – on the grounds that it lessens the quantity of chromosomes from 46 chromosomes or 2n to 23 chromosomes or (n depicts a solitary chromosome set). in people, the decrease division results in two sperm cells each with 23 chromosomes or an egg cell with 23 chromosomes and one disposed of polar body. the second division – or meiosis ii – is called equational division. the two sperm cells split again creating four sperm cells, each with 23 or n chromosomes. in oogenesis, the egg cell and polar body partition to shape the ovum and two extra polar bodies. along these lines, the posterity are guaranteed to get one portion of the chromosomes from the mother and one half from the dad.
