Answer:
a sequence of DNA responsible for coding a protein = gene
The complex range of alleles an organism carries for... = genotype
an allele that determines... = dominant gene
the observable characteristics= phenotype
Humans have approximately 24,000 genes, but fruit flies are not far behind, with approximately 14,000 genes.
The rigth answer is D.
The wavefront or wavefront is an equal phase surface of a wave, i.e., these points have the same travel time from the source. The concept is used to describe the propagation of waves such as sound or electromagnetic radiation (light, radio waves, etc.). In a homogeneous and isotropic medium, in which the waves propagate without deformation, two types of particular waves are distinguished according to whether the wavefronts are spheres (spherical wave) or planes (plane wave).
