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:
It indicates that core histone genes were present in the last common ancestor of yeasts, plants, and animals
Explanation:
Histones are highly basic proteins that can strongly interact with DNA, which is packaged into nucleosomes, the basic structural and functional unit of chromatin. Each nucleosome is composed of approximately 147 base pairs of DNA wrapped around a core of eight histone proteins (two copies of four types of histones H3, H4, H2A, H2B). These core histones are evolutionarily conserved across eukaryotic kingdoms in terms of sequence and structure. Therefore, DNA-packaging into nucleosomes is considered a constraint for the evolution of core histones. Moreover, the presence of conserved core histones in eukaryotic kingdoms (e.g., yeast, plant, and animal kingdoms) is strong evidence that histone-mediated DNA packaging was presumably present in the last common ancestor of eukaryotic genomes.
This is more of a personal question about how well you know yourself, no one can answer this for you.
The correct answer in this question is option A. Biochemical analysis uses similarities in DNA sequences as evidence for evolutionary relationships. Scientists believed that two species with almost the same protein structure are more likely to have a closer relationship. DNA hybridization and gene sequencing are two types of analysis that can be used.
