Explain how the circulatory system is able to transport the blood under high pressure from the heart to the rest of the body
Transport of blood under high pressure is done through the concerted efforts of the heart and arteries.
The circulatory system is the network of the heart, arteries, veins, and capillaries responsible for the movement of blood around the body.Transporting blood under high pressure can be explained in the following steps:
Contraction of the heart ventricles creates blood under high pressureHigh pressured blood is removed from the heart through the arteries. In addition, the arteries are able to contract and expand, thus are elasticThe lumen of the arteries is narrow thus helping in maintaining high pressureAs a result of the above, the high pressure of blood is maintained and transported to the extremities of the body.

Which factor can decrease the rate of a chemical reaction?
A low activation energy
B high pressure
C low temperature
D high concentration of enzyme
(c)Low Temperature of the Reactants can decrease the rate of a chemical reaction.
How temperature effects the rate of a chemical reaction
Chemical reactions typically occur faster at higher temperatures. Food can spoil quickly when left on the kitchen counter. However, the lower temperature inside of a refrigerator slows that process so that the same food remains fresh for days. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.Thus decrease in the temperature of a reaction can help in decreasing the rate of a chemical reaction.Lower the temperature lower the chemical reaction rate.

Which pattern is caused by fire burning upward
Pour patterns
V-pattern
Rundown pattern
Inverted cone
Please only answer if you know
V-pattern caused by fire burning upward. Thus, the correct option is B.
What do V patterns in burn mean?V-Patterns: Because fire burns up in a V-shape, a fire that starts at an outlet next to a wall will leave a char pattern that will help identify the source. A fire that is hotter than usual, such as one aided by an accelerant, may have an extremely narrow V-shape.
The observable or quantifiable physical changes or recognisable shapes produced by a fire effect or combination of fire effects are known as fire patterns, sometimes known as burn patterns. The changes that occur in or on a substance as a result of exposure to fire are known as fire effects.
