How long should you hold a stretch?A. 0–5 seconds
B. 2–15 seconds
C. 5–10 seconds
D. 10–30 seconds

Answers

Answer 1
Answer: The answer is letter D.

A stretch should be ideally held between 10 to 30 seconds to inhibit proper muscle lengthening and shortening of fibers. Anything shorter than this duration would lead to no benefit of the stretch, while anything longer can lead to injuries. Stretching is an important component in a safe rainting program of an individual that is set to reach a specific fitness goal. There are two types of stretches and these are active stretches (done before a workout) and passive stretches (done after a workout).

Over the counter diet pills typically containa. antidepressants.
b. vitamins.
c. anticoagulants.
d. diuretics.

Answers

Diurectics make the body rid itself of fluid.  So you will see weight loss but it is not real, there is not fat lost.

Final answer:

Over the counter diet pills typically contain active ingredients like fibers, fat burners, and appetite suppressants. Most also contain vitamins to supplement a balanced diet. Diet pills can aid weight loss when used correctly, but they should not be relied upon as a sole solution.

Explanation:

Over the counter diet pills typically contain various active ingredients meant to aid in weight loss. These can include fibers, fat burners, and appetite suppressants. Majority of these pills also contain vitamins to supplement a balanced diet. It's important to note that while diet pills can support weight loss efforts when used correctly, they can't magically melt away pounds. A balanced diet and regular physical activity are vital for healthy weight loss.

Which condition causes plaque to accumulate on the walls of the arteries which makes them thicken and lose elasticity

Answers

The correct answer is Atherosclerosis. What this disease does is create layers of white blood calls and fibrofatty tissue to make the arteries thicken. This also includes things like triglycerides and cholesterol. This increases blood pressure and can sometimes be deadly for people, but it is usually noticed way after it establishes itself.

What is the difference between a tornado and a thunderstorm?

Answers

Answer:

Explanation:

A tornado and a thunderstorm are two different weather phenomena. Here's a summary of the key differences between them:

1) Formation: A thunderstorm is a localized weather system characterized by thunder, lightning, and precipitation. It forms when warm, moist air rises, cools, and condenses into clouds, releasing energy in the form of thunder and lightning. On the other hand, a tornado is a violent and rotating column of air that extends from a cumulonimbus cloud to the ground. Tornadoes typically form within severe thunderstorms.

2) Structure: Thunderstorms are large-scale weather systems with multiple cloud layers, including cumulus, cumulonimbus, and sometimes stratus clouds. They can produce heavy rain, strong winds, hail, and lightning. Tornadoes, on the other hand, are narrow, funnel-shaped columns of air that rotate violently around a central axis. They are typically much smaller in size compared to thunderstorms.

3) Impact: Thunderstorms can produce a range of hazardous weather conditions, including heavy rain, strong winds, lightning strikes, and hail, which can cause property damage, disrupt power supply, and pose risks to human safety. Tornadoes, however, are among the most destructive and dangerous weather phenomena. They can cause significant damage to structures, uproot trees, and generate strong winds known as tornado vortexes that can reach speeds over 300 mph (480 km/h).

4) Duration: Thunderstorms typically last for a few hours, while tornadoes are short-lived and usually last for a matter of minutes. The lifespan of a tornado can vary, with some lasting only a few seconds, while others can persist for more extended periods.

A thunderstorm is a localized weather system that produces thunder, lightning, and precipitation. At the same time, a tornado is a violent and rotating column of air that forms within severe thunderstorms. Thunderstorms are larger in scale and can produce various hazardous weather conditions, whereas tornadoes are smaller and more destructive, characterized by their narrow funnel shape and intense rotational winds.

Final answer:

A thunderstorm is a weather event characterized by lightning, thunder, and precipitation, while a tornado is a violent and destructive rotating column of air associated with thunderstorms. Tornadoes have funnel-shaped clouds and strong winds, while thunderstorms can produce heavy rain, strong winds, and hail.

Explanation:

A thunderstorm and a tornado are both weather phenomena, but they have distinct differences. A thunderstorm is a weather event that is characterized by the presence of lightning, thunder, and precipitation. It is caused by the rapid upward movement of warm, moist air, which leads to the formation of cumulonimbus clouds. Thunderstorms can produce heavy rain, strong winds, hail, and sometimes tornadoes.

On the other hand, a tornado is a specific type of severe weather event that is associated with thunderstorms. It is a violent and destructive rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud. Tornadoes are characterized by their funnel-shaped cloud and strong winds, which can reach speeds of over 200 miles per hour.

While thunderstorms can produce tornadoes, not all thunderstorms do. Tornadoes are relatively rare compared to thunderstorms, and they typically occur in specific regions known as Tornado Alley in the United States. Tornadoes can cause significant damage to structures and pose a threat to human life.
