Answer:

1. A low- pressure weather system can cause a thunderstorm to develop. 

2.Thunder is caused by lightning. When a lightning bolt travels from the cloud to the ground it creates a channel. Once the light is gone the air collapses back in and creates a sound wave that we hear as thunder.

3. One condition that is necessary for a thunderstorm include warm air and moisture.

4. The dangers of a blizzard include getting lost in the snow and freezing to death.

5. In my opinion, a hurricane would be the most difficult storm to face because hurricanes can severely impact your life due to their damage. For example,winds can damage houses, trees, and any other property. Even if your home is safe, flooding aftermath can occur. When homes are destroyed, people may have to rebuild homes and towns.

Name and describe the phase change that occurs when solid carbon dioxide (dry ice) is placed in an open container at room temper

Valentin [98]

If you put a lump of solid carbon dioxide (dry ice) in a paper cup or
on a paper plate on the kitchen counter, it gets smaller and smaller
and finally it just disappears, but you never see a puddle around it
like you would with regular ice!

Carbon dioxide has no liquid phase when the pressure on it is less than
about 5 times normal atmospheric pressure. So in the kind of pressure
that we like to live in, dry ice goes straight to gas when it melts. That kind
of behavior is called "sublimation", and we say that the dry ice "sublimes".

Every substance has some pressure limit like that. For water, it's 0.006 of
normal atmospheric pressure. At any pressure lower than that, liquid water
can't exist, and an ice cube sublimes ... it melts directly into water vapor
without a puddle.

When blood clots, an enzyme is activated to change a protein from one form into another.

Answer:

Hey mate!!

<h2>Process of blood-clotting</h2>

The mechanism to prevent excessive loss of blood from the body is called blood clotting.

<h3>Steps in blood clotting:</h3>

At the site of cut, damaged cells and platelets release thromboplastin.
This thromboplastin with the help of calcium ions,converts prothrombin into thrombin.
In the presence of calcium ions,thrombin reacts with soluble fibrinogen and converts it into insoluble fibrin.
Fibrin is a solid substance which forms threads and a meshwork at the site of cut.
Blood cells trapped in the network of fibrin.The blood shrinks and squeezes out the rest of plasma in the form of clear liquid.
The solid mass which is left behind is called clot.

Primary producers generally form the smallest trophic level of a pyramid of energy true or false

baherus [9]

False Primary Producers must form the largest base, because if there is a shortage of them, then there will be only a small amount for all others. This i guess can be called the Doppler's effect
('bit of history in here)
