Answer:
cross-sectional study
Explanation:
A cross-sectional study is an observational research that has to do with data analysis of variables or sane set of variable obtained at a particular point of time (a snap shot)across a sample population. It is also called cross-sectional analysis, transverse study or prevalence study.
In this study type, the variable is said to be constant. It can either be a descriptive (to show the frequency and distribution of the study topic in a particular area) cross-sectional study or an anakytical cross-sectional study (to show the relationship between two related or unrelated variables).
As in this case study, if a significant amount of the population view a particular sport program more than the others, the researcher can conduct further studies to understand the reason behind the variation in populations that viewed a particular sport program – like a longitudinal study.
In a cross-sectional study, to determine the prevalence, multiple parameters are estimated simultaneously – questions, observations, and answers. Prevalence = amount of cases at a certain period in time / population of people at that certain period.
The cross-sectional studies is swift to perform, variblels are retrieve once, help determine different outcomes with the prevalence value too, can be used for descriptive analysis and to promote further research.
Thanks you so much !!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
The process in cell division by which the nucleus divides, typically consisting of four stages, prophase, metaphase, anaphase, and telophase, and normally resulting in two new nuclei, each of which contains a complete copy of the parental chromosomes.
Answer:
A) Decreases;increase
Explanation:
When there are high levels of carbon dioxide in the respiratory system, the blood pH level decreases, causing respiratory rate to increase.
This condition is acidosis because not enough CO2 escapes lungs hence CO2 accumulates and decreases pH of blood, making it more acidic. As blood pH drops (becomes more acidic), the parts of the brain that regulate breathing are stimulated to produce faster and deeper breathing to increase the amount of carbon dioxide exhaled to bring our body to the ideal pH.
