Answer:
Selection Bias
Explanation:
Hope it helps!
If lost individuals are more or less likely to be exposed than those successfully traced, the study results may suffer from selection bias. Selection bias occurs when the study sample is not representative of the population, and certain individuals or groups are overrepresented or underrepresented in the sample.
What can happen in case of such results ?In this case, the results of the study may be biased because the lost individuals are not represented in the sample or are represented differently than those who were successfully traced. This can lead to inaccurate conclusions and affect the validity of the study.
Selection bias can occur in various types of studies, including observational studies and clinical trials. For example, in an observational study, researchers may recruit study participants from a particular clinic or hospital, which may not represent the general population.
Similarly, in a clinical trial, patients who agree to participate may have different characteristics or health status than those who decline to participate, which can affect the generalizability of the study results.
To reduce the risk of selection bias, researchers can use random sampling techniques to select study participants and ensure that the study sample is representative of the population of interest. In clinical trials, randomization can also help to balance the characteristics of participants in the treatment and control groups, which can reduce the risk of bias.
In addition to selection bias, there are other types of bias that can affect the validity of study results, including measurement bias, confounding bias, and publication bias. Researchers should be aware of these potential sources of bias and take steps to minimize their impact on study results.

What sequence of exercises should you follow when training all major muscle groups in a workout?.
When training major muscle groups in a workout, large muscle exercises (squats) should be done first, followed by smaller muscle exercises (shoulder press). Single-joint exercises should be done after multiple-joint exercises.
What are muscles?
The human body has more than 600 muscles. Some muscles help the body move, lift or sit still. Others may help in digestion of food, breathing or sight.
Muscles are actually soft tissues. Different jobs are occupied by different types of muscles. Maintaining a healthy lifestyle helps keep the muscles strong and work like they should.
Some muscles we control voluntarily, with the help of the nervous system, whereas some muscles are involuntary. Muscles are of different types. They are as follows:
Skeletal: smooth muscles work with the bones, tendons and ligaments. Skeletal muscles are attached to bones by tendons all over the body. They support the weight of the body and help in movement. These are also voluntary muscles.
Cardiac: Cardiac muscles line the walls of the heart. These are involuntary muscles. Cardiac muscles help the heart pump blood that travels through the cardiovascular system
Smooth: Smooth muscles line the insides of organs like the bladder, stomach and intestines. These muscles are also involuntary. They play an important role in many body systems such as the female reproductive system, male reproductive system, urinary system and respiratory system.

True or False: During a strength training exercise, the agonist muscle contracts and the antagonist muscle stretches to allow the contraction.
An eccentric contraction causes a muscle to lengthen while it is still producing force; as a result, resistance is greater than the force produced. Contractions that are eccentric can be forced or voluntary.
When a force applied to a muscle exceeds the momentary force produced by the muscle itself, an eccentric (lengthening) muscular contraction happens, forcing the muscle-tendon system to lengthen while being forced to contract.

why is it important to know diabetes type 2
HURRY
I" M ON A TEST.
It is important to know whether someone has diabetes type 1 or type 2 because the two types of diabetes are caused by different factors and require different treatments. Diabetes type 1 is an autoimmune disorder in which the body's immune system attacks and destroys the cells that produce insulin, a hormone that regulates blood sugar levels. This type of diabetes typically develops in childhood or adolescence, and requires lifelong treatment with insulin injections.
On the other hand, diabetes type 2 is a metabolic disorder that is caused by a combination of factors, including genetics, obesity, and inactivity. In diabetes type 2, the body's cells become resistant to insulin, or the pancreas does not produce enough insulin to keep blood sugar levels within a normal range. This type of diabetes typically develops in adults, and can often be managed with lifestyle changes, such as exercise and a healthy diet, along with medication.
Knowing which type of diabetes someone has is important because the treatment and management of the two types of diabetes are different. For example, someone with diabetes type 1 will need to take insulin injections for the rest of their life, whereas someone with diabetes type 2 may be able to manage their condition with lifestyle changes and medication. Proper diagnosis and treatment of diabetes is important for maintaining good health and preventing complications.
The average number of calories in a 1. 5-ounce chocolate bar is 225. Suppose that the distribution of calories is approximately normal with a standard deviation of 10. Find the probability that a randomly selected chocolate bar will have less than 200 calories.
According to the normal distribution, there is a 0.3023 = 30.23% chance that a chocolate bar chosen at random will have between 200 and 220 calories.
Normal Distribution Equation
In a normal distribution with mean and standard deviation, the z-score of a measure X is given by:
[tex]Z = X-u/[/tex]σ
It measures how many standard deviations the measure is from the mean.
After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
In this problem:
Mean of 225 calories, thus.
The standard deviation of 10 calories, thus.
The probability that a chocolate bar will have between 200 and 220 calories is the p-value of Z when X = 220 subtracted by the p-value of Z when X = 200, thus:
X = 220:
[tex]Z=X-u/[/tex]σ
[tex]Z = 220-225/10\\Z = -2.5[/tex]
[tex]Z = -2.5[/tex] has a p-value of 0.3085.
X = 200:
[tex]Z = X-u/[/tex]σ
[tex]Z = 200-225/10\\ Z = -2.5\\Z = -2.5[/tex]has a p-value of 0.0062.
0.3085 - 0.0062 = 0.3023.
0.3023 = 30.23% probability that a randomly selected chocolate bar will have between 200 and 220 calories.

What is hunger?
Hunger is characterized as a state in which a person lacks the physical or financial means to consume enough food to sustainably meet basic nutritional demands. The term "hunger" in the context of hunger relief refers to more than just the universal want for food that all people experience, also known as an appetite. When malnutrition is prevalent and people are beginning to starve to death due to a lack of access to enough nourishing food, the most severe type of hunger results in the declaration of famine.When there is hunger or persistent undernourishment "few calories are consumed than the minimum amount of nutritional energy needed (MDER). The minimal desirable energy expenditure (MDER) is the amount of energy required to maintain a weight that is minimally acceptable for one's height." Due to differences in climatic and cultural conditions, the FAO uses various MDER levels for various nations. The typical strategy is to utilize a yearly "balance sheet," comparing the predicted annual total caloric intake to the minimal dietary energy requirement. Hunger is distinguished by the FAO standards from malnutrition and food insecurity.Therefore, option a is the correct answer
