Hello. Your question is incomplete, which makes it difficult to answer, but we can consider that the girl's experiment went wrong because she used a DNA sequence that only corresponds to introns that are not capable of encoding amino acids. Therefore, you could explain to the girl that her experiment did not work, because the introns do not encode amino acids, which prevents the clones from developing proteins that are essential for their survival, since the amino acids are the protein-building molecules .
Introns are important for the control of gene expression, but they cannot encode any amino acid, without which the organism cannot survive.
Answer:
Meristematic tissue.
Explanation:
Meristematic tissue contains stem cells which can differentiate into permanent cells. This tissue is at all continuous growth points in a plant, at the apical buds ( where leaves and flowers form) and at the ends of roots.
- dermal tissue is in animals - this refers to the tissues associated with skin
- vascular tissue refers to the xylem and phloem of a plant- no growth occurs here.
- Permanent tissue is tissue which has already differentiated and grown. This is the final form.
The action potential has three main stages: depolarization, repolarization, and hyperpolarization. Depolarization is caused when positively charged sodium ions rush into a neuron with the opening of voltage-gated sodium channels.
