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 by parasympathetic nerves causes the heart rate to slow down.

The two branches of the autonomic (involuntary) nervous system regulate heart rate. The parasympathetic nervous system and the sympathetic nervous system (SNS and PNS) (PNS). To increase heart rate, the sympathetic nervous system (SNS) produces the catecholamines epinephrine and norepinephrine. The hormone acetylcholine is released by the parasympathetic nervous system (PNS) to reduce the heart rate. Your heart rate may briefly increase due to stress, coffee, and excitement, whereas it may temporarily decrease due to meditation or deep, steady breathing. Any amount of exercise will raise your heart rate, which will stay up as long as you keep exercising.

What are potential impacts on society and the environment of using a genetic approach to improving food productivity? Do you thi
Lilit [14]

Answer:

- Society: the use of genetic improving techniques may have a positive impact through crop improvement of traits of agronomic importance such as, for example, resistance to biotic and abiotic stresses.

- Environment: the development of genetically modified crops conferring resistance to pesticides may have a negative effect on wildlife species  (both plants and animals) and humans living in such agroecosystems.

Explanation:

In crops, genetic improvement technologies can be defined as the techniques associated with the development of better crop varieties, i.e., varieties that have higher grain yield, produce more biofuel, higher fiber content, etc. Genetic improvement techniques include, among others, selective breeding and genetically modified organisms. In crops, genetic improvement techniques have the potential to reduce hunger in the world. However, it is important to note that genetic engineering may be associated with the horizontal transference of genes and the development of genetically modified organisms (GMO), which may have harmful effects on wildlife species and humans, thereby GMO crops must be carefully assessed before their release into the field.

Which characteristics can be used to classify the tree as a gymnosperm rather than “any other type of seed” plant?
erica [24]
1. Naked Seeds, Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination. Pine cones are one example. For ease you might think of the gymnosperms as conifers, such as yew and Scots pine.
