Which process contributes to the formation of layers in protoplanets when unstable elements release particles and energy? compaction evaporation radioactive decay collision of space materials

Radioactive decay

Explanation:

Radioactive decay refers to the natural breakdown of unstable elements or nucleus which lead to the release of energy or particles like alpha particles or beta particles.

It result in the formation of layers in protoplanets.

The four different types of radioactive decay are,

Alpha particles

Beta particles

Gamma decay

Positron emissions.

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.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
