Answer:
Control group: volunteer stationary bike riders in a pollution-free chamber
Experimental group: volunteer stationary bike riders in a chamber filled with air pollutants common to Los Angeles
Independent variable: exposure to air pollution
Dependent variable: The heart rates (physical fitness) of the volunteer riders.
Explanation:
In a scientific experiment, data is compared between the control group and experimental group to ascertain the effect of the independent variable on the dependent variable. A control group is the group in an experiment that is not treated with the independent variable i.e. the independent variable is controlled while the experimental group is the group that is treated with an independent variable.
N.B: The independent variable is the variable controlled by the experimenter in order to influence the dependent variable (measurable outcome).
In this experiment, the independent variable is the AIR POLLUTION the volunteer riders are exposed to while the dependent variable is the PHYSICAL FITNESS/ HEART RATES of the volunteer riders, which is dependent on the exposure to air pollution (independent variable).
The control group in this experiment is the volunteer riders placed in a POLLUTION-FREE CHAMBER where the independent variable cannot influence or have any effect on the measurable variable (dependent). The experimental group is the volunteer riders placed in a CHAMBER FILLED WITH AIR POLLUTANTS. The independent variable (air pollution) has been changed in the experimental group.
When planting vegetables it is very important to know the climate of the area, its usual patterns, and how will that affect the growth and development of the crops. The soil quality too is very important, as it is the basis for the development of the root-stock of the crops.
If we have a temperate type of climate, than we have four different seasons, meaning different weather patterns throughout the year. We can take onions, radish, and peppers as vegetables of choice. The onions can be planted in mid-autumn, as they will need more moisture, and they are resilient to low temperatures, thus will not have problems in the winter, and in the spring they will already have the basis so will grow quickly and be larger. The radish can be planet in late winter or early spring, in a period when there is more precipitation. It is not a vegetable that likes high temperatures, so with its quick development, it will be able to develop the tuber by late spring. The peppers can not sustain low temperatures, so they should be planted in late spring. They also like warm weather and lot of water, so it will be needed to water them a lot in the hot and dry period. They will manage to develop and produce the vegetables by the end of the summer, thus not getting damaged by the cold nights in the autumn.
Answer:
The answer to the question is C
Explanation:
It is used for all I and II and III
Methylphenidate refers to a CNS stimulant mainly used in the treatment of ADHD (attention deficit hyperactivity disorder) in children between the age of 6 to 12, adults up to the age of 65, and adolescents. It can also be used in the treatment of narcolepsy.
However, the application of the drug may also bring some side-effects with it. Some of the common side-effects related to medicine are decreased appetite, headache, hallucinations, sweating, fever, dizziness, increased heart rate, weight loss, and others.
In the given case, due to the application of the drug, the child is having hallucinations. Thus, in the given case, the nurse should recommend the client to report the manifestations as quick as possible, and discontinue the use of medicine.
