A positive correlation exists when two variables move in the same direction as one another. A basic example of positive correlation is height and weight—taller people tend to be heavier, and vice versa. In some cases, positive correlation exists because one variable influences the other.
In statistics, a positive correlation shows that changes in one variable will relate to the same type of changes in a second variable. The data is usually displayed in a scatterplot, which shows the linear relationship between variables in a positive correlation graph.
Answer:
The answer is A: Epithelial tissue.
Explanation:
The epithelial tissue is the tissue that is mostly exposed to the external environment. The epidermis is the outermost layer of the skin, it is a type of epithelial tissue, covering large spaces of the body. It consists mostly of dense accumulations of cells attached to each other that allow them to communicate with each other.
Answer:
C) pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis is highly selective.
Explanation:
The difference between pinocytosis and receptor-mediated endocytosis is that, pinocytosis is nonselective in the molecules it brings into the cell, whereas receptor-mediated endocytosis is highly selective.
Answer: The best resource to develop a differential diagnosis is the physical examination and the medical history.
Explanation:
Possessing knowledge of different diseases, shows its applicability when performing the physical examination, which allows you to recognize the semiology studied in the patient and when observing it, be inclined to different diagnoses, I discard the other possibilities because, diseases may not require for its diagnosis Know the vital signs or the reading of capnography or a cardiac monitor, that although they are very useful, the diagnosis must be based on the clinic, currently these become aids, not being essential if the clinical suspicions or needs are not recognized of the patient, technology provides many resources, but the clinical history since antiquity is the basis for the study of a disease, without it the main data that inclines us to different diagnostic probabilities would not be known.
The effects of exergaming on pain, postural control, technology acceptance and flow experience in older people with chronic musculoskeletal pain: a randomized controlled trial.
In this study, it was studied how exergaming affected postural control and discomfort in older individuals with chronic musculoskeletal pain. Technology acceptability, flow experience, perceived physical exertion, mental effort, and heart rate were secondary outcomes.
<h3>How was this study carried out?</h3>
Fifty-four older adults (age: 71 ± 5 years) with chronic musculoskeletal pain were randomized into 2 groups.
The first group was provided with exergaming training by the Interactive Rehabilitation and Exercise System. And the 2nd group was given basic gym-based exercise. And their pain was measured after a span of 6 weeks.
<h3>What result did they get?</h3>
Afterward, when the pain survey was done, the 1st group showed significant reductions in pain intensity as compared to the 2nd group. The 2nd group rather showed significant improvements in the ML SD range over time.
