What is dromotropic effect?
Dromotropic effect is the effect on conduction of current. It could be positive or negative depending on the final outcome. A negative dromotropic effect would mean decrease in conduction activity of current while positive would mean increase in conduction activity of current.
Why does radiation cause hair loss?
Radiation damages hair follicles, leading to hair loss. The high-energy radiation disrupts the growth and division of cells in the hair follicles, causing them to stop producing hair. This is a common side effect of radiation therapy for cancer treatment.
What if an effect of adaptive radiation?
An effect of adaptive radiation is the diversification of a single ancestral species into a variety of different forms to exploit different ecological niches. This can lead to the evolution of new species with specialized adaptations for specific environments or resources. Adaptive radiation is often associated with rapid speciation and can result in an increase in biodiversity within a relatively short period of time.
The standard unit of radiation related to biologic hazard is?
The standard unit of radiation related to biologic hazard is the Sievert (Sv). It is used to measure the potential biological damage caused by radiation exposure. It takes into account both the type of radiation and its effect on different tissues in the body.
What would be the effect on action potential conduction at a region of axon where the disease had its effect?
The disease may disrupt the normal flow of ions necessary for generating and propagating action potentials, leading to decreased conduction velocity or even blockage of action potentials in that region of the axon. This could result in impaired communication between neurons and affect the overall function of the nervous system in that area.
What form of heat is caused by the greenhouse effect?
There are three types of heat transfers: conduction, convection and radiation. The heat transfer caused by the greenhouse effect is radiation.
What type of heat energy dose a telly give out radiation or convection or conduction?
Radiation, convection and conduction are not different types of energy, but different methods of conveying the energy. The heat energy from a television set will be conveyed mainly through conduction and convection, ie the casing will heat up through conduction and the air above the televison will become heated through convection. There will be heat transmitted by radiation, but this will quickly encounter air molecules which will then add to the convection effect.
What form of heat transfer is caused by the greenhouse effect?
There are three types of heat transfers: conduction, convection and radiation. The heat transfer caused by the greenhouse effect is radiation.
Which two methods of heat transfer are possible with liquids which of the two has greater effect?
The two methods of heat transfer possible with liquids are conduction and convection. Convection generally has a greater effect on heat transfer in liquids compared to conduction, as it involves the movement of the liquid itself, helping to distribute heat more efficiently.
What keeps the temperature from getting too high in hot places?
In hot places, heat is typically dissipated through processes like evaporation, convection, and radiation. Sweating cools the body via evaporation, while breezes provide a cooling effect through convection. Radiation also plays a role, as heat is emitted from the body and surrounding objects.
What are the ways which heat can be transferred?
There is a special mechanism that controls heat transfer.
How does the air around a thermometer effect the thermometers temperature?
Conduction and radiation. Heat always flows from the hotter of two objects into the colder - until their temperatures are the same.
Explain two ways that earths atmosphere gets heated?
by convection and conduction
What is the temperatures and the climate?
temperature has high effect on temperature as bcz of breezes
What are 2 ways the earths atmosphere get heated?
The Earth's atmosphere is heated through solar radiation, where sunlight is absorbed by the Earth's surface and then re-radiated as heat into the atmosphere. Atmospheric heating also occurs through the greenhouse effect, where certain gases trap heat in the atmosphere by preventing it from escaping into space.
How does a thermos flask reduce heat loss by radiation?
Vaccum between thermos walls does NOT prevent radiation, however the other forms of heat transfer(convection and conduction) are more or less eliminated. Radiation effect of heat transfer may be reduced by applying a layer of reflective material inside the bootles - to reflect the emmision back inwards.
Explain the three mechanism of heat transfer in Earth atmosphere?
Green house gas absorbs the radiation that would actually be emitted into space. This raises the earth's temperature. Clouds, absorption through the surface of the earth, earth's magnetic field changes, etc., relate to heat transfer in the earth-atmosphere system.
