Answer:
a. longitudinal
Explanation:
A longitudinal study examines a given group over a long period of time, so collecting data from the same group of 30 people over their lifetime certainly fits that definition. It's more like an evolution study.
A cross-sectional compares different groups at the same point in time. So, it's more like a survey.
A microgenetic is much focused in time, providing multiple data sets in a short time to examine rapid evolution of a subject.
An experimental study design will make interactions and experiments with the study group, while this is not the case here apparently, and experimental is usually for a much shorter period than a generation.
Answer:
It reduces strength.
Explanation:
It not desirable to produce concrete mixtures of a higher consistency than normal because the strength of the concrete decreases. Consistency plays an important role in the determination of strength of concrete. Less water than normal quantity in concrete increases the consistency but decreases strength due to incomplete chemical reaction while on the other hand, adding more water would increase water-cement ratio and reduces consistency as well as strength of the concrete so that's why necessary amount of water and cement should be added to get higher strength.
E) the township-and-range survey system was based on a geometric grid pattern......
The three possible ways we could attempt an interpretation of the finding are listed below.
1. Society as a whole has failed its adolescents by not ensuring that they are brought up in healthy homes.
2. Parents have not created healthy homes for their children. Childbearing comes with a set of responsibilities on those who engage in the activity.
3. It is imperative to ensure that adolescents receive adequate love and understanding in healthy homes so that they may behave healthily.
Thus, since one cannot give what she or he does not have, society must ensure that we have healthy homes for the growth of adolescents and the nurturing of healthy habits.
