Answer :
Choice A i think
1. A forensic pathologist would most likely perform a forensic autospy. Forensic pathologists focus on cause of death by examining a bod or corpse. They perform postmortem examinations.
2. Insect activity will begin immediately if a body is left in the open. That is why insect activity can help investigations with determining certain things such as time of death, where the person died and the like.
3. A light meal will digest in about 1-2 hours. Digestion rates can give useful information about when a person had died. Medium meals take about 3-4 hours to digest and heavier meals take about 6 hours.
4. Indicative acts are actions or behaviors that may or may not have taken place before someone dies. Indicative is suggestive, so it may or may have happened. When you say indicative acts you are referring to what may have happened (or may not) based on certain circumstances, observations or evidence.
Answer:
Chi-square analysis cannot be used to check for significant difference in the number of knee injuries among four sports.
Explanation:
The chi-square analysis is a statistical procedure that is used to test association between measured variables or goodness of fits of a set of measured variables to expected outcomes.
<em>In the case of testing for significant difference, chi-square analysis cannot be used as testing for significant difference in two or more means requires using t-test, analysis of variance, or any other relevant statistical procedure.</em>
To compare number of knee injuries reported among four sports for significant difference, the most suitable statistical procedure would be analysis of variance.

Answer: Heart Rate
Explanation:
When you are running in a race, one feedback mechanism that happens as you increase exercise and muscle activity is that, your heart rate also increases. Your heart rate increases because it needs to sustain the body's need of more energy to be supplied to the different parts of the body during an activity.
Answer:
Physiological reactions to stress in the alarm stage include: <em>increased heart rate and blood pressure, dilated pupils, rapid and shallow breath, and increased cortisol levels.</em>
Explanation:
Hans Seyle, a medical doctor proposed a model called the General Adaptation Syndrome (GAS) to explain the effects and stages of coping with the stress. The GAS model has three stages, known as:
1. Alarm stage
2. Resistance stage
3. Exhaustion stage
The <em>alarm</em> stage is the first stage of responding to stress. During this stage, the fight-or-flight response is activated when an individual is experiencing stress. This stage involves the following physiological reactions:
1. Increased heart rate
2. Increased blood pressure
3. Dilated pupils
4. Rapid and shallow breath
5. Increased cortisol levels
