After the industrial revolution, the dark colored bark on trees caused which kind of peppered moths to flourish?
the dark colored peppered moth
the light colored peppered moth
both peppered moths
neither peppered moths

Option A, the dark colored peppered moth

Explanation:

During the industrial revolution, the color of bark of the trees became dark. Due to this the predators could easily detect the light colored moths on the dark colored bark of the trees.  

This lead to evolution of light colored moth resulting into dark colored moths through the process of natural selection which made the newly evolved moth population more prominent to the predation attack.  

It became difficult for the predators to trace moth on the tree barks as they became capable of camouflaging against the color of  bark

Hence, option A is correct

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
