Answer:
biologie is klote, net zoals je nu doodgaat
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.
The answer is: Carnivores
Organisms at the third trophic level are secondary consumers. These secondary consumers prey on the primary consumers which are animals that eat plants or herbivores. Secondary consumers are best described as carnivores because they don't eat plants. They only eat animals that consume plants like cows and chicken.
Answer:
Cells help our body in many ways. if we didnt have cells out bodys would not function. Cells actually provide structure for the body and take in nutrients from food. They then convert those nutrients into energy, and carry out specialized functions.
