<span>If a nurse notices that an accident victim cannot clench his teeth, there is a good chance that his trigeminal nerve has been affected. This nerve is located inside the brain and its primary purpose is to transmit sensations from a person's face to the brain. Damage to this nerve could cause the patient to be unable to clench their teeth.</span>
Answer: The answer is Anthocerophyta
Explanation: Anthocerophyta are widespread and occur in the temperate & tropical zones. The species of plants in this phylum have horn-shaped sporophytes which are known as "flower horn". As in other bryophytes, the sporophyte of this phylum remains attached to its parent gametophyte throughout its life, but unlike these other plants, the sporophyte continues to grow throughout its life; this happens as a group of cells at the base of the horn divide repeatedly. They also possess stomates, which exchange gases between the plant and the air.
The mitochondrial genome evolution in Anthocerophyta is closer to that of seed plants but not as dynamic.
Answer:
The effect might be due to the gene expression.
Explanation:
The effect might be due to the variation in the gene expression in the organism. In this way, the variety of the genetic pool is likely to result in a diversity of the gene pool or genome. Because of the mutation and the environmental factors, there is likely to be a slight variation of the species. This results in a slight difference in the phenotypic expression.
