Describe some of the effects that dilated blood vessels will have on blood pressure.
grin007 [14]
Since pressure is force per unit area, blood pressure could be thought as the force exerted by the blood to the surface area of your blood vessels. When your blood vessels dilate, it means that they expanded. The result would be faster flow of blood. When this happens, the force of the blood is not any more concentrated on your blood vessels because there is more room available. 

Think of a faucet where tap water flows. When you stopper the faucet with your finger, you feel the force of the water. The pressure builds up as manifested by the sound your faucet makes. But when you release your finger, the water rushes through and flows faster. The pressure is released. Therefore, when your blood vessels are dilated, your blood pressure decreases.

In most cases, the two major climatic factors affecting the distribution of organisms in terrestrial ecosystems are _____. In mo
Anna35 [415]

Answer:

Water and temperature

Explanation:

Water and temperature are the two most important factors that regulate the distribution of organisms in terrestrial habitats. Water is required for survival by living beings. The availability of water is limited in many habitats such as desert habitats. In such land habitats with water scarcity, the organisms adapted to withstand the limited water availability are found.

Likewise, temperature also affects the distribution of organisms in terrestrial habitats. The presence of temperature conditions below and above the tolerance range of the organisms restricts their geographical distribution. Temperature regulates the enzyme kinetics. Metabolic pathways are catalyzed by enzymes that function under optimal temperature conditions only. Water serves as a medium for metabolic reactions and also regulates body temperature.
