Hich takes places as a result of double fertilization in an angiosperm? double fertilization produces a triploid zygote and diploid endosperm. double fertilization produces a diploid zygote and triploid endosperm. double fertilization produces a triploid zygote and a triploid endosperm.

An ovary in an angiosperm flower contains one ovule, in which the cells divide to produce an egg and two polar nuclei. These egg and polar nuclei are haploid. The pollen grain introduces sperm cells which are also haploid. The two haploid sperm cells are introduced into the pollen tube  and finally reaches to the ovules.  The first sperm cell fuses with the egg and zygote form is diploid in ploidy. The second sperm cell will fuse with the two polar nuclei, and a endosperm form is triploid in ploidy.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
