Effectus [21]

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.

Other than phosphocreatine breakdown, the fastest way to resupply atp to a muscle is:_______
lesya [120]

Other than phosphocreatine breakdown, the fastest way to resupply atp to a muscle is:_______

anaerobic glycolysis.

What is phosphocreatine breakdown?

Adenosine triphosphate, sometimes known as ATP, is used by the body's muscles to drive contractions. One molecule of ATP is digested into ADP, adenosine diphosphate, and an inorganic phosphate when it is used in the contraction process.

The requirement to regenerate ATP is critical because the muscles' finite supply of ATP is consumed during muscle activity very quickly. The molecule creatine phosphate is one method by which this ATP supply is renewed (or phosphocreatine).

Creatine phosphate converts a high-energy phosphate to ADP during the ATP regeneration process. ATP and creatine are the reactions byproducts. Intake of meat and internal manufacture by the liver and kidneys are the two main ways to get creatine phosphate.

Which of the following statements correctly describes the difference between the leading and the lagging strands of DNA during D
Mrrafil [7]

The answer is; A & C

The lagging strand is replicated in fragments called Okazaki fragments, each initiated by a primer. The fragments are later joined into one strand by DNA ligase. Replication occurs by adding nucleotides to the 3’ end of a preceding nucleotide. Because the lagging strand is antiparallel to the leading strand, the replication of the lagging strand is in the opposite direction as the replication fork direction. This is why the lagging strand is replicated in fragments because replication is being carried out by a single DNA polymerase (moving in the direction of the replication fork) per replication fork.

<span>Potatoes are also known as tubers and they commonly make up most of the carbohydrate needs that the body can get from food. It is made up of parenchyma tissue that makes the plant have the ability of cloning and low metabolic activity. They are commonly used for experimentation as a “model tissue” because of these characteristics. <span>
