1) “Melopsittacus undulatus” (leia-se os dois nomes em itálico), conhecido popularmente como periquito-australiano, pode apresentar plumagem nas cores azul, amarela, branca e verde. Essa característica é condicionada por dois pares de genes, com segregação independente, que têm interação entre si. A cor branca é condicionada por genes homozigotos recessivos. Indivíduos que apresentam em ambos os Ioci pelo menos um dos alelos dominantes são verdes. Quando apresentam um um Ioci com genes recessivos e o outro com, pelo menos, um alelo dominante, são azuis ou amarelo. Do cruzamento de dois indivíduos duplamente heterozigotos, espera-se encontrar:

It is expected to observe individuals exhibiting green, yellow, blue, and white colors in a phenotypic ratio of 9:3:3:1, respectively.

Explanation:

This example is a classic case of a dihybrid cross involving two unlinked genes that differ in the same observed trait. In this case, the genotype double homozygous recessive is white, while the presence of one dominant allele in one of these genes results in individuals with either blue or yellow color. Finally, the presence of two dominant alleles results in individuals with blue color.

Phenotypic and genotypic ratios:

gene 1 two alleles U u

gene 2 two alleles N n

Cross:  

UuNn x UuNn

uunn: white color (1/16)

U_nn: yellow color (3/16)

uuN_: blue color (3/16)

U_N_: green color (9/16)

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

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.
