Answer:
lizard tails with vivid blue reflectance evolved in communities with either weasel or snake predators, which can both detect blue wavelengths. However, lizard tail UV reflectance was much higher in populations with only snake predators, perhaps because snakes can detect UV, yet weasels cannot. Finally, a cryptic brown tail evolved on islands where birds are the primary lizard predator. Because birds have keen visual acuity, a brown, camouflaged tail may be more advantageous.
Explanation:
Insulin is a hormone made by the pancreas that allows your body to use. After you eat food and your blood sugar level rises, cells in your pancreas (known as beta cells) are signaled to release insulin into your bloodstream. Insulin then attaches to and signals cells to absorb sugar from the bloodstream.
I believe (B) is the best option due that it mentions the reason causing natural selection with limited supplies competition increases making it more likely for the strongest individuals to survive
Answer:
Deletion in a nearby gene, chromosome breakage, and translocation of the gene to a heterochromatic location.
Explanation:
Transposable components (TEs), also known as "jumping genes," are DNA sequences that moves starting with one area on the genome then onto the next, in some cases making or reversing mutation and changing the cell's hereditary character and genome size.
At the point when the transposon is extracted from the original site, it may remove a portion of the gene sections alongside it. This prompts the presence of a serious phenotype. Transposable components can likewise cause chromosome breakage. On the off chance that the whole gene is moved alongside the transposon to a heterochromatic location, the gene gets silenced
