Respuesta:
B. pastoreo excesivo de animales de granja
Porque son lugares secos.
Explicación:
Las políticas e infraestructuras que promueven la agricultura en las tierras de pastoreo que no pueden mantener sistemas viables de cultivo, contribuyen a la desertificación. La mayoría de las áreas de tierras secas (el 65%) son tierras de pastoreo que son más adecuadas para el pastoreo sostenible que para el cultivo.

Answer:
75% of their offsprings will be red birds, and 25% will be with birds, this is the phenotype.
The genotype will be BB, Bb, and bb.
Explanation:
he information that we have is that B is the dominant allele for red feathers in a bird, and b is the recessive allele for white feathers in a bird.
If we cross two heterozygous birds that means that both progenitors are Bb, if we draw a Punnet Square we can see that 75% of the offsprings will be red birds, and 25% will be white birds, this is the phenotype, which is what we can physically see of the genes.
The genotypes will be BB, Bb, and bb, these are the different combinations of genes that can happen, and that explains why a bird is red or white, which is due to the dominance of one allele over the other.
