Which phrase describes convection?

a transfer of heat between two objects that are touching

b transfer of heat by the actual movement of warmed matter

c the process in which energy is released by molecules breaking apart

D the process in which energy is emitted by one object, transmitted through space, and absorbed by another

b transfer of heat by the actual movement of warmed matter is the correct answer,

Explanation:

Convection: It is a type of heat transfer by the movement of a warm matter.

Convention only occurs in gases and liquids because it includes liquids and gases that are moving physically.

natural convection and forced convection are types of convection,

Examples of convection

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
