Reaction time, speed, and power are the most important skill-related fitness components that every sprinter must excel at during the race.
Strength is defined as the ability to generate force (lifting heavy weights) speed: the ability to move quickly (sprinting) Endurance is the ability to withstand fatigue (running a marathon) Flexibility is the ability to achieve a wide range of motion at the joints (doing a split) Power is defined as the ability to exert maximum muscular contraction in an explosive burst of movements. Strength and speed are the two components of power. (For example, jumping or a sprint start) Aerobic endurance is also known as cardiovascular endurance. Marathon runners and distance cyclists need a high level of aerobic endurance to be able to work for an extended period of time during a race.

Answer:
The correct answer is D. resting phase
Explanation:
Diastole is the resting phase when relaxation of heart muscles takes after contraction(systole). In this phase blood from veins and coronary sinus comes into the auricles and ventricles because of the pressure in the heart is less than veins and opening of A-V valve.
When both auricles and ventricles are relaxed it is called joint diastole. Joint diastole is called complete cardiac diastole and is 0.4 sec long. After the joint diastole auricular systole occurs in which auricles are contracted and ventricles are still relaxed called ventricular diastole.
After the end of auricular systole ventricles contraction starts and auricular relaxation occurs called auricular diastole.
A primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak
<h3>What is antigenic drift?</h3>
Antigenic drift is a phenomenon that causes small changes or mutations in the genes of influenza viruses leading to changes in their surface proteins of the virus, which are HA (hemagglutinin) and NA (neuraminidase).
For this reason, new influenza vaccines are produced yearly to alter the effects that may emerge as a result.
Thus, a primary reason for needing a new vaccine for influenza each year is that there could be mutation of surface proteins leading to a new outbreak

It is very reasonable for the nurse to believe that this individual taking clopidogrel, has a background of coronary artery disease.
What is the function of the clopidogrel drug?
- It is an antiplatelet drug. It stops platelets, a kind of blood cell, from congregating and creating a potentially harmful blood clot.
- If one has a higher risk of developing blood clots, using clopidogrel can help.
- Clopidogrel has been shown to reduce the risk of myocardial infarction, stroke, and vascular mortality in people with atherosclerosis and in those who have had coronary stents implanted.
- ITP, CVA, and hemophilia are not suggested conditions to be treated with it.
When not to use clopidogrel?
For some folks, clopidogrel is not a good choice. In order to ensure that this medication is safe for you, let your doctor know if you:
- possess an ulcer in the stomach or have had ulcers in the past
- have experienced brain bleeding (a brain hemorrhage)
- having a bleeding condition, such as hemophilia

Answer:
<u>Ethanol prevents toxicity by competing with Ethylene glycol for metabolism by alcohol dehydrogenase.</u>
Explanation:
Ethylene glycol is an organic compound usually used in antifreeze solutions, solvents and cleaners.
It is abused during self-destruction and accidental intakes.
<u>In the body, ethylene glycol is acted upon by alcohol dehydrogenase and is converted into glycolate and oxalate.</u>
Glycolate and oxalate are both nephrotoxic/ kidney damaging substances. Oxalate precipitates calcium oxalate stones in the kidney. Ethylene glycol poisoning also causes high anion gap metabolic acidosis.
In order to prevent ethylene glycol poisoning, the patient is infused with ethanol, ethanol <u>prevents toxicity by competing with Ethylene glycol for metabolism by alcohol dehydrogenase.</u> In this way, ethylene glycol is not metabolized and the formation of nephrotoxic substances is prevented. Alcohol dehydrogenase instead reacts with ethanol to form acetaldehyde.
