Answer:

Capillaries are the blood vessels with the smallest diameter and those closest to the surface of the skin. The blood that circulates through them is therefore closer to the outside air than the blood in the rest of our blood vessels. As the capillary dilates, a greater amount of blood is exposed to the air, which allows it to cool down and our body temperature to be maintained.

Explanation:

Blood is a solution where solutes and cells are found and that participates in homeostatic mechanisms such as the control of body temperature, helping to regulate respectively the preservation and elimination of heat. Blood vessels are the routes of the cardiovascular system, which are responsible for being a means of transport for blood with and without oxygen that reaches all tissues and returns to the heart. In very hot weather, surface thermoreceptors signal the brain that something needs to be done to dissipate heat. For this reason, a vasodilation process is activated, which allows blood to flow to the outermost layers of the skin. This promotes a heat exchange with the environment, which helps the individual to lower their body temperature. Cold causes a decrease in blood flow by reducing the size of the vessel (arteries or veins) through which blood and other substances circulate. By reducing the size of the vessel, the substances that circulate in the blood are also reduced. The heat causes an increase in the size of the blood vessels, which generates greater transport of nutrients through the blood.

What main criterion determines major divisions in tje geologic time scale?
bagirrra123 [75]

Answer:

A) Times of major climate change

Explanation:

The geological time scale is based on major changes in Earth's climate history. This is because of the reason that climate governs the geological processes on Earth. In geology, we study the ages with the help of stratigraphical data where sediment deposition and the fossils it is hosting are the keys to understand the environmental conditions at that particular time. These conditions didn't change significantly unless the climate was changed. An example is the extinction of dinosaurs during K/T boundary event (mass extinction). The most likely reason is the hitting of a meteorite on Earth that changed the climate of Earth in a short period making it least favorable for many organisms to survive.

On the other hand, the occurrence of huge events cannot be used to establish a geological time scale because sometimes, the changes happen more slowly.

Similarly, shifts in the Earth orbits are cyclic however geological time scale doesn't reflect cyclic changes. The same climate can establish in different ages but these events are not used not as a criterion to establish a geological time scale.

In the end, the time span of humans on Earth is very small when compared with the overall geological time scale. Humans record exists from Pleistocene (2,580,000 to 11,700 years ago) to today whereas geological time scale starts in the Archean Eon (4.0 billion to 2.5 billion years ago).
