Answer:
The correct answer is B. DNA helicase first unwinds the double helix around the +1 site.
Explanation:
The helicase is an enzyme that specifically breaks the hydrogen bonds of the bases in the transcription process. As E. Coli is a prokaryote, then, the transcription only occurs in one point of the circular DNA. The promoter region indicates where the DNA polymerase has to start replicating and the Topoisomerase unwinds the parts of the DNA that are being excessively twisted because of the separation of the two strands.
Answer:
The correct answer is D. The seventh cranial nerve is the facial nerve.
Explanation:
The facial nerve is a mixed cranial nerve, that is, it contains both sensory and motor fibers, present in mammals including humans in which it forms the seventh cranial nerve. Being a cranial nerve, it emits two fibers, one that runs on the right side of the face and the contralateral on the left. It starts of the brain stem, just between the brainstem and the medulla and controls the facial expression muscles, as well as the taste in the previous two thirds of the tongue. It also supplies parasympathetic preganglionic innervation to various nerve nodes in the head and neck.
Answer:
The correct hypothesis would be - C) Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades.
Explanation:
Burmese pythons are the invasive species in this new region as they originally found in South Africa, and also one of the largest snakes so they lack natural predators in this new setting or region.
These snakes depend on both types of food which means they are omnivorous and eat both herbivore and carnivores prey.
Thus, the correct answer is - Burmese pythons lack natural predators and can utilize a wide variety of food sources in the Everglades.
