In England, peppered moths have two color forms, light and dark. Dark is a dominant trait. Until about 1850, the majority of

ehidna [41]

Theory of natural selection by Charles Darwin explains the moth appearance in England. The theory of genetics describes this as a mere shift of trait due to environmental factors.

<h3><u>Explanation:</u></h3>

Peppered moths are the moths found in England from a long time ago. The environment before the industrial revolution was pure and pollution free, which led to the growth of the white variety of moths as they were able to camouflage better with the bark of the trees from their hunters. The white trait were the parents, and fertilization between the two recessive traits gave rise to the recessive traits only.

But with the industrial revolution, the pollution increased to a huge extent, leading to deposition of smokes and soot on trees bark where white variety of the white moths got easily recognizable. This led to the black moths which now can camouflage better. Thus the nature selected black variety over white variety for better survival, and the white variety reduced dramatically.

What artery supplies the chin/jaw region of the head with blood?

Ede4ka [16]

The artery that supplies the chin and jaw region of the head with blood is the facial artery which is a branch of the external carotid artery. All blood from the head arises from the common carotid artery wherein it is divided to internal carotid artery (major blood supply of the brain along with the basilar artery on the posterior side) and external carotid artery (major blood supply of the head other than the brain).

The external carotid artery has 8 major branches (from inferior to superior): (1) superior thyroid artery, (2) ascending pharyngeal artery, (3) lingual artery, (4) facial artery, (5) occipital artery, (6) posterior auricular artery, (7) maxillary artery, and (6) superficial temporal artery.

Attached is a simplified photo of the branches of the external carotid artery.
