<span>Which storm is likely to cause quick destruction along a narrow path?
</span>
<span>A.tornado
B.hurricane
C.thunderstorm

Your answer would be a A.Tornado


</span>
<span>Which clouds are best associated with a thunderstorm?
A.high cumulonimbus
B.towering funnel clouds
C.swirling clouds with a calm center</span>
Thunderstorms occur in association with a type of cloud known as a cumulonimbus. So, <span>A.high cumulonimbus


 </span>
<span>Which statement best describes the formation of a hurricane?
A.Air pressure differences over the ocean cause fast, spinning winds.
B.An updraft of warm, moist air builds a cumulonimbus cloud.
C.A downdraft of air meets spinning updrafts.
</span>
Hurricanes begin as tropical storms over the warm moist waters of the Atlantic and Pacific Oceans near the equator. As the moisture evaporates it rises until enormous amounts of heated moist air are twisted high in the atmosphere.
<span>A.Air pressure differences over the ocean cause fast, spinning winds.

</span>
<span>How are hurricanes and thunderstorms similar?
A.Both cover an area as large as 650 km.
B.Both involve the formation of large cumulonimbus clouds.
C.Both form when warm air rises, then cools quickly to form clouds.</span>

Hurrica<span>nes  and thunderstorms are both convective storms fueled by warm, moist air. </span><span>C.Both form when warm air rises, then cools quickly to form clouds.

</span><span>Is this statement true or false?
Hurricanes are classified by three stages in which updrafts of air billow up, updrafts and downdrafts swirl the wind up and down, then downdrafts cause clouds to come apart.
A.True
B.False

This would be true

</span>
<span>Which severe weather condition forms over warm, tropical areas?

A. tornado
B. hurricane
C. thunderstorm
</span>
Thunderstorms result from the rapid upward movement of warm, moist air. They can occur inside warm, moist air masses and at fronts. As the warm, moist air moves upward, it cools, condenses, and forms cumulonimbus clouds that can reach heights of over 12.45 miles.

Hurricanes develop in warm, tropical regions where the water is at least 80 degrees Fahrenheit  The storms also require moist air and converging equatorial winds.

A tornado can form where winds blow at different speeds causing rotation which can tighten and speed into a funnel cloud if caught in the flow of air moving into the storm. Rain and hail can cause the funnel to bend downward.

<span>B. hurricane is your answer


Hope it helped :)

Which of the following is NOT true regarding the sounds associated with the heart? Select one: a. The "lub-dub" sound originates
Valentin [98]

Answer:

B) The "lub-dub" sound originates from blood turbulence through the heart.

Explanation:

The systole and diastole in the heart produce the lub and dub sound in the heart.

The systole represents the contraction of both left and right ventricles and pumps the blood to the body and the right ventricle to the lungs. This involves the opening and closing of the valves. The closing of the atrioventricular valves produces lub sound.

At the end of the systole or ventricular contraction or when the blood has been pumped to the aorta and the pulmonary valves then the semilunar valves present in the aorta and pulmonary closes. This produces a sound dub.

Therefore,lub dub is associated with the physical contraction of the heart but not the turbulence of the blood.

Thus, the selected option is the correct answer.

<h2>Issues with animal research in bred</h2>

Explanation:

  • Since all animals are reared and brought up in a similar domain, they may contrast from animals reproduced in an alternate settlement Animal activist may think that its unscrupulous to utilize animals in look into Working with animals requires IRB conventions that protect the prosperity of the animals, making it difficult to play out certain examinations on them.
  • Scientific researchers keep up that despite the fact that animal research, (as some other models in vitro or on the other hand human), doesn't generally convey ideal outcomes for human pertinence, it's still – in blend with important non-creature techniques - the essential method to do research to comprehend living systems and to give the most ideal affirmation of the impacts of new medicines preceding the primary clinical preliminaries in people.
  • Clinical preliminaries are not ready to give results with 100% precision because of the huge inconstancy of the human population. The medicines improvement process including in silico, in vitro, pre-clinical (animals) and clinical (human) stages diminish the hazard for the Human population as a whole.
