Kay [80]3 years ago
5 0

Answer: C. Using coal to generate electricity

Explanation:

Sustainable practice can be define as the practice which ensures the use of resources in a manner so that these resources remain available for the present as well as for the future generations.

C. is the correct option this is because of the fact that coal is the non-renewable resource. The excess use of coal for generation of electricity is likely to limit the concentration of coal available in a region. Hence, the use of coal cannot be considered as sustainable practice.

IrinaK [193]

In the heterozygous state (w +/w), a variegated eye is produced, with white and red patches. The following statements are true in relation to this experiment:

b. When heterochromatin spreading does not reach the new location of the w + allele, the gene will be transcribed, producing red eye patches.

c.  When heterochromatin spreading encompasses the new location of w + allele, the gene is transcribed, producing white eye patches.

d. Even though eye color phenotypic variegation exists within the eye, all cells have the same genotype.

Explanation:

Heterochromatin in droshophila has genes which gets expressed by position effect variegation. In some normally active cells genes are silenced in some due to transposition  of genes which causes change or variegating in phenotype.

This change is due to change in position of the gene in the genome and chromosome but no change in gene.

The variegation in drsophilla melanogaster shows that white gene was not damaged.

The rearrrangement of gene takees place at pericentric heterochromatin.

Heterochromatin is required for maintaining genome integrity and regulating gene expression. When spread in neighboring region it can inactivate the genes present there.

The genes taking part in variegation remains same hence no change in genotype.
