what effect does the nervous system have on the heart rate? stimulation by sympathetic nerves sets the resting heart rate of the pacemaker cells in the sa node. stimulation by sympathetic nerves causes the pacemaker cells of the av node to depolarize more rapidly than the pacemaker cells of the sa node. stimulation by either the sympathetic or parasympathetic nerves causes pacemaker cells in the sa node to depolarize more slowly. stimulation by parasympathetic nerves causes the heart rate to slow down. the nervous system does not directly affect the heart rate.
The effect nervous system has on the heart rate is
Stimulation with the aid of parasympathetic nerves causes the coronary heart charge to slow down.
the 2 branches of the autonomic (involuntary) worried machine regulate coronary heart price. The parasympathetic apprehensive system and the sympathetic apprehensive gadget (SNS and PNS) (PNS).
To increase heart rate, the sympathetic worried gadget (SNS) produces the catecholamines epinephrine and norepinephrine.
The hormone acetylcholine is released with the aid of the parasympathetic apprehensive gadget (PNS) to reduce the coronary heart fee. Your heart rate may briefly increase due to stress, espresso, and pleasure, whereas it is able to temporarily lower because of meditation or deep, constant respiration.
Any quantity of exercise will enhance your coronary heart fee, a good way to stay up as long as you hold exercising.

scientists suspect that modern horses have different dietary habits than horses that lived long ago. what is the most reliable source that scientists can use to prove that horses have changed over time?
Compare the teeth of modern horses to fossilized teeth from ancient horses.
The sharper points associated with a diet of leaves replaced the cusps of a fruit-eater in the horses' teeth some 33 million years ago, causing a noticeable change. The rain forests were vanished at this point, and the weather had become chilly.
According to Mihlbachler, "the signal we are receiving in the shift in the food of horses is extremely compatible with what we understand about how the environment was changing.
The teeth of certain prehistoric horses, which were most closely linked to contemporary horses, underwent a significant alteration around 18 million years ago.
Their teeth developed a more intricate surface that was more adapted for chewing difficult vegetation, especially grasses, which contain silica particles that can damage teeth. The teeth also started to get longer.

Type A and type B are two categories made by a pair of cardiologists based on various personality traits exhibited by an individual
Who discovered type A and type B personalities?Two cardiologists are credited with developing the type A and type B personality theories. Meyer Friedman and RH Rosenman conducted research on potential coronary disease causes in the 1950s. Friedman and Rosenman created a system for classifying individuals as either type A, type B, or type AB after conducting a nine-year study of approximately 3,000 healthy males between the ages of 35 and 59. (for those who defied easy categorization).
What were their conclusions made by them?They concluded that those with type A personalities are more prone to be preoccupied with status and success. They are frequently compulsive workers who could struggle with impatience and low self-esteem. Additionally, they are more likely to lash out quickly. Unsurprisingly, Friedman and others have identified this personality type that has been linked to an increased risk of heart disease. People with type B personalities are more likely to be tolerant and even-tempered, and they also report higher levels of life satisfaction.

You and your friends are in the food court at the mall drinking soda. You notice that the level of liquid in the straw is higher than the liquid in the cup. What are the twwo water properties
Answer:
Cohesion and capillary action
Explanation:
Cohesion and capillary action are the answers. Cohesion is the attraction of water to water. Capillary action is when water travels up without something helping or propelling it. So, using cohesion, the liquid in the example is attracted to itself and sticks together. Capillary action occurs, making the stuck- together liquid travel up the straw and be higher than the liquid in the cup.

2. Even though it has a much lower temperature, why does a warm pool have more thermal energy (heat)
than a cup of boiling water?
At 0°C and 100°C, respectively, on the Celsius scale, water freezes. A lot more water is present in the swimming pool, though. In spite of the fact that the tea is hotter than the pool's water, the pool has more thermal energy than the tea does.
Thermal energy, expressed in joules or J, is the measure of how much heat a thing has.
Temperature: An object's temperature, expressed in Celsius degrees, refers to how hot or cold it is. However, the swimming pool has a greater thermal energy storage capacity than a cup of coffee since it has more water in it.

How does a prism separate white light into the different colors that compose it?.
The prism separates white light into the different colors that compose it, as white light passes through a prism, shorter wavelengths refract more than longer wavelengths, and the colors separate.
Visible light commonly referred to as white light is made up of several different colors. It is common to see these hues as light travels through a triangular prism. The white light is broken down into its component colors—red, orange, yellow, green, blue, and violet—as it passes through the prism. Dispersion is the division of visible light into various colors.
Each wavelength of light is refracted by a slightly different amount when it travels through a prism due to the angles and planar faces of the object. The most refracted color and one with the highest frequency is violet. Red is refracted the least and has the lowest frequency. White light is spread out and divided into the colors of the spectrum as a result of how differently each hue is refracted, which causes each color to bend at a different angle.

what are the major groups and types of collagen, their functions, and their locations in connective tissues?
Collagen is a protein present most abundantly in the body. Its main function is to provide structure, strength and support throughout the body. There are 5 major types found in different locations like cartilage, bones, etc.
The main component of the body's skin, muscles, bones, tendons, ligaments, and other connective tissues is collagen. Additionally, it is present in blood vessels, organs, and intestinal lining. About 30% of the total protein comes from it. The three primary amino acids in collagen are proline, glycine, and hydroxyproline. These amino acids combine with the right quantity of copper, vitamin C, manganese, and zinc to create triple-helical protein fibrils.
Functions of collagen include:
• Form fibroblasts in the middle skin layer (dermis) which grows new cells.
• Replace dead skin cells.
• Providing a protective covering for organs.
• Giving elasticity, structure and strength to the skin.
• Help in blood clotting.
Based on the assembly of the molecules, cell components and the position of the collagen, there are 28 types of collagen identified.
The major five types of collagen are:
• Type I – is densely packed and makes up 90% of the body’s collagen. It provides structure to the skin, bones, tendons and ligaments.
• Type II – provides joint support and is found in elastic cartilage.
• Type III – muscles, arteries and organs include this type.
• Type IV –layers of the skin include this type.
• Type V – is found in the cornea, some layers of skin, hair and tissue of the placenta.

According to the random lining of homologous chromosomes, one single pair of homologous chromosomes has 2 possible orientations. The number of random alignments in the cell is 2ⁿ. Here, 2ⁿ = 16.
What is the random alignment of homologous chromosomes?The random lining of homologous chromosomes (metaphase 1) is one of the three mechanisms involved in genetic variation, together with Crossing-over and random fertilization.
Gamete formation involves the random and independent segregation of the alleles.
During metaphase I, homologous pairs migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles.
The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells.
During Anaphase I, occurs independent segregation of homologous chromosomes. In this stage, each of the homologous chromosomes migrates forward to the pole they are facing.
Each of the chromosomes has two possibilities for orientation at the plane. They can face one pole or the other, and this random arrangement is what introduces variation into the gametes.
This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair.
The number of different random alignments of the homologous chromosomes equals the number of gametes with different combinations, which is 2ⁿ, where n = number of homologous pairs.
