To hit a overhand, you jump and smack the ball with your palm when the ball goes over the net
To hit a underhand, you put the ball on the undominant hand and you throw it up then you smack it with your palm
the advantages of a underhand is it might not work and may hit the net
advantage of a overhand is, it goes fast and the opponent might not see it coming.
Answer:
Body type
Explanation:
Not an expert on this topic, but this is because everyone's body is different, so that affects what the healthy outcome is. For example, if someone has a body type that is slightly overweight or underweight from birth (from genes and such) they can't help having a different body. So what that means is that their healthy weight might be considered overweight/underweight compared to more "normal" body types.
Answer:
Well, Type one Diabetes is A chronic condition in which the pancreas produces little or no insulin. if you don't know what insulin is a hormone is needed to allow sugar (glucose) to enter cells to produce energy. Different factors, including genetics and some viruses, may contribute to type 1 diabetes. Although type 1 diabetes usually appears during childhood or adolescence, it can develop in adults
Explanation:
the symptoms that could happen are:
- Increased thirst
- Frequent urination
- Bed-wetting in children who previously didn't wet the bed during the night
- Extreme hunger
- Unintended weight loss
- Irritability and other mood changes
- Fatigue and weakness
- Blurred vision
some of these may not happen but if some do talk to a doctor about it
Based on the results of the study shown below, the epidemiologist has reason to worry because the incidence rate increased over four times the previous level as shown below:
- number of HIV cases = 440 persons
- new incidence rate = 2.25 per 1000 persons
<h3>What is prevalence and incidence rate?</h3>
Prevalence rate is the proportion of persons in a population who have a particular disease or attribute at a specified point in time or over a specified period of time.
- Prevalence rate = number of cases/total population × 100%
Incidence rate is the proportion of new cases of a condition observed within a given period of time.
- Incidence rate = number of new cases/population at risk × 1000
- population at risk = total population - previous cases
The number of people who had HIV in January 2012 is calculated as follows:
- number of HIV cases = prevalence rate × total population
number of HIV cases = 2.2% × 20000
number of HIV cases = 440 persons
Incidence rate between February 2012 and January 2013 is calculated as follows:
Incidence rate = 50/(20000 - 440) × 1000
Incidence rate = 2.25 per 1000 persons.
Based on the new incidence rate, the epidemiologist has reason to worry because the incidence rate has increased over four times the previous level.
