In a marine ecosystem, a large already existing population of purple-colored sea urchins increases as the starfish eats other colors is a type of directional selection.
<h3>What is directional selection?</h3>
Directional selection is the type of natural selection in which an extreme phenotype is favored and has its frequency increased in the population. It is the type of selection that causes changes more quickly than the others, being the type most used in artificial selections.
With this information, we can conclude that in a marine ecosystem, a large already existing population of purple-colored sea urchins increases as the starfish eats other colors is a type of directional selection.
The purple coloured sea urchins increases as starfish eats other colours, this type of selection represents Disruptive selection.
<h3>What is Disruptive selection?</h3>
Disruptive selection is also called diversifying selection, describes changes in population in which extreme values for a trait that are favored over intermediate values.
So we can conclude that purple coloured sea urchins increases as starfish eats other colours, this type of selection represents Disruptive selection.
The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream.
The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.
so correct option is D) The lac operon will function normally.
